For the first two thirds of the 20th century, Algeria's high fertility rate caused its population to grow rapidly. However, about a decade after independence from France in 1962, the total fertility rate fell dramatically from 7 children per woman in the 1970s to about 2.4 in 2000, slowing Algeria's population growth rate by the late 1980s. The lower fertility rate was mainly the result of women's rising age at first marriage (virtually all Algerian children being born in wedlock) and to a lesser extent the wider use of contraceptives. Later marriages and a preference for smaller families are attributed to increases in women's education and participation in the labor market; higher unemployment; and a shortage of housing forcing multiple generations to live together. The average woman's age at first marriage increased from about 19 in the mid-1950s to 24 in the mid-1970s to 30.5 in the late 1990s.

Algeria's fertility rate experienced an unexpected upturn in the early 2000s, as the average woman's age at first marriage dropped slightly. The reversal in fertility could represent a temporary fluctuation in marriage age or, less likely, a decrease in the steady rate of contraceptive use.

Thousands of Algerian peasants - mainly Berber men from the Kabylia region - faced with land dispossession and economic hardship under French rule migrated temporarily to France to work in manufacturing and mining during the first half of the 20th century. This movement accelerated during World War I, when Algerians filled in for French factory workers or served as soldiers. In the years following independence, low-skilled Algerian workers and Algerians who had supported the French (known as Harkis) emigrated en masse to France. Tighter French immigration rules and Algiers' decision to cease managing labor migration to France in the 1970s limited legal emigration largely to family reunification.

Not until Algeria's civil war in the 1990s did the country again experience substantial outmigration. Many Algerians legally entered Tunisia without visas claiming to be tourists and then stayed as workers. Other Algerians headed to Europe seeking asylum, although France imposed restrictions. Sub-Saharan African migrants came to Algeria after its civil war to work in agriculture and mining. In the 2000s, a wave of educated Algerians went abroad seeking skilled jobs in a wider range of destinations, increasing their presence in North America and Spain. At the same time, legal foreign workers principally from China and Egypt came to work in Algeria's construction and oil sectors. Illegal migrants from sub-Saharan Africa, particularly Malians, Nigeriens, and Gambians, continue to come to Algeria in search of work or to use it as a stepping stone to Libya and Europe.

Since 1975, Algeria also has been the main recipient of Sahrawi refugees from the ongoing conflict in Western Sahara. More than 1000,000 Sahrawis are estimated to be living in five refugee camps in southwestern Algeria near Tindouf.

More than a decade after the end of Angola's 27-year civil war, the country still faces a variety of socioeconomic problems, including poverty, high maternal and child mortality, and illiteracy. Despite the country's rapid post-war economic growth based on oil production, about 40 percent of Angolans live below the poverty line and unemployment is widespread, especially among the large young-adult population. Only about 70% of the population is literate, and the rate drops to around 60% for women. The youthful population - about 45% are under the age of 15 - is expected to continue growing rapidly with a fertility rate of more than 5 children per woman and a low rate of contraceptive use. Fewer than half of women deliver their babies with the assistance of trained health care personnel, which contributes to Angola's high maternal mortality rate.

Of the estimated 550,000 Angolans who fled their homeland during its civil war, most have returned home since 2002. In 2012, the UN assessed that conditions in Angola had been stable for several years and invoked a cessation of refugee status for Angolans. Following the cessation clause, some of those still in exile returned home voluntarily through UN repatriation programs, and others integrated into host countries.

Argentina's population continues to grow but at a slower rate because of its steadily declining birth rate. Argentina's fertility decline began earlier than in the rest of Latin America, occurring most rapidly between the early 20th century and the 1950s, and then becoming more gradual. Life expectancy has been improving, most notably among the young and the poor. While the population under age 15 is shrinking, the youth cohort - ages 15-24 - is the largest in Argentina's history and will continue to bolster the working-age population. If this large working-age population is well-educated and gainfully employed, Argentina is likely to experience an economic boost and possibly higher per capita savings and investment. Although literacy and primary school enrollment are nearly universal, grade repetition is problematic and secondary school completion is low. Both of these issues vary widely by region and socioeconomic group.

Argentina has been primarily a country of immigration for most of its history, welcoming European immigrants (often providing needed low-skilled labor) after its independence in the 19th century and attracting especially large numbers from Spain and Italy. More than 7 million European immigrants are estimated to have arrived in Argentina between 1880 and 1930, when it adopted a more restrictive immigration policy. European immigration also began to wane in the 1930s because of the global depression. The inflow rebounded temporarily following WWII and resumed its decline in the 1950s when Argentina's military dictators tightened immigration rules and European economies rebounded. Regional migration increased, however, supplying low-skilled workers escaping economic and political instability in their home countries. As of 2015, immigrants made up almost 5% of Argentina's population, the largest share in South America. Migration from neighboring countries accounted for approximately 80% of Argentina's immigrant population in 2015.

The first waves of highly skilled Argentine emigrant workers headed mainly to the United States and Spain in the 1960s and 1970s, driven by economic decline and repressive military dictatorships. The 2008 European economic crisis drove the return migration of some Argentinean and other Latin American nationals, as well as the immigration of Europeans to South America, where Argentina was a key recipient. In 2015, Argentina received the highest number of legal migrants in Latin America and the Caribbean. The majority of its migrant inflow came from Paraguay and Bolivia.

Migration continues to transform Belize's population. About 16% of Belizeans live abroad, while immigrants constitute approximately 15% of Belize's population. Belizeans seeking job and educational opportunities have preferred to emigrate to the United States rather than former colonizer Great Britain because of the United States' closer proximity and stronger trade ties with Belize. Belizeans also emigrate to Canada, Mexico, and English-speaking Caribbean countries. The emigration of a large share of Creoles (Afro-Belizeans) and the influx of Central American immigrants, mainly Guatemalans, Salvadorans, and Hondurans, has changed Belize's ethnic composition. Mestizos have become the largest ethnic group, and Belize now has more native Spanish speakers than English or Creole speakers, despite English being the official language. In addition, Central American immigrants are establishing new communities in rural areas, which contrasts with the urbanization trend seen in neighboring countries. Recently, Chinese, European, and North American immigrants have become more frequent.

Immigration accounts for an increasing share of Belize's population growth rate, which is steadily falling due to fertility decline. Belize's declining birth rate and its increased life expectancy are creating an aging population. As the elderly population grows and nuclear families replace extended households, Belize's government will be challenged to balance a rising demand for pensions, social services, and healthcare for its senior citizens with the need to reduce poverty and social inequality and to improve sanitation.

Benin has a youthful age structure – almost 65% of the population is under the age of 25 – which is bolstered by high fertility and population growth rates. Benin’s total fertility has been falling over time but remains high, declining from almost 7 children per women in 1990 to 4.8 in 2016. Benin’s low contraceptive use and high unmet need for contraception contribute to the sustained high fertility rate. Although the majority of Beninese women use skilled health care personnel for antenatal care and delivery, the high rate of maternal mortality indicates the need for more access to high quality obstetric care.

Poverty, unemployment, increased living costs, and dwindling resources increasingly drive the Beninese to migrate. An estimated 4.4 million, more than 40%, of Beninese live abroad. Virtually all Beninese emigrants move to West African countries, particularly Nigeria and Cote d’Ivoire. Of the less than 1% of Beninese emigrants who settle in Europe, the vast majority live in France, Benin’s former colonial ruler.

With about 40% of the population living below the poverty line, many desperate parents resort to sending their children to work in wealthy households as domestic servants (a common practice known as vidomegon), mines, quarries, or agriculture domestically or in Nigeria and other neighboring countries, often under brutal conditions. Unlike in other West African countries, where rural people move to the coast, farmers from Benin’s densely populated southern and northwestern regions move to the historically sparsely populated central region to pursue agriculture. Immigrants from West African countries came to Benin in increasing numbers between 1992 and 2002 because of its political stability and porous borders.

Bolivia ranks at or near the bottom among Latin American countries in several areas of health and development, including poverty, education, fertility, malnutrition, mortality, and life expectancy. On the positive side, more children are being vaccinated and more pregnant women are getting prenatal care and having skilled health practitioners attend their births.

Bolivia’s income inequality is the highest in Latin America and one of the highest in the world. Public education is of poor quality, and educational opportunities are among the most unevenly distributed in Latin America, with girls and indigenous and rural children less likely to be literate or to complete primary school. The lack of access to education and family planning services helps to sustain Bolivia’s high fertility rate—approximately three children per woman. Bolivia’s lack of clean water and basic sanitation, especially in rural areas, contributes to health problems.

Between 7% and 16% of Bolivia’s population lives abroad (estimates vary in part because of illegal migration). Emigrants primarily seek jobs and better wages in Argentina (the principal destination), the US, and Spain. In recent years, more restrictive immigration policies in Europe and the US have increased the flow of Bolivian emigrants to neighboring countries. Fewer Bolivians migrated to Brazil in 2015 and 2016 because of its recession; increasing numbers have been going to Chile, mainly to work as miners.

Botswana has experienced one of the most rapid declines in fertility in sub-Saharan Africa. The total fertility rate has fallen from more than 5 children per woman in the mid 1980s to approximately 2.4 in 2013. The fertility reduction has been attributed to a host of factors, including higher educational attainment among women, greater participation of women in the workforce, increased contraceptive use, later first births, and a strong national family planning program. Botswana was making significant progress in several health indicators, including life expectancy and infant and child mortality rates, until being devastated by the HIV/AIDs epidemic in the 1990s.

Today Botswana has the third highest HIV/AIDS prevalence rate in the world at approximately 22%, however comprehensive and effective treatment programs have reduced HIV/AIDS-related deaths. The combination of declining fertility and increasing mortality rates because of HIV/AIDS is slowing the population aging process, with a narrowing of the youngest age groups and little expansion of the oldest age groups. Nevertheless, having the bulk of its population (about 60%) of working age will only yield economic benefits if the labor force is healthy, educated, and productively employed.

Batswana have been working as contract miners in South Africa since the 19th century. Although Botswana’s economy improved shortly after independence in 1966 with the discovery of diamonds and other minerals, its lingering high poverty rate and lack of job opportunities continued to push workers to seek mining work in southern African countries. In the early 1970s, about a third of Botswana’s male labor force worked in South Africa (lesser numbers went to Namibia and Zimbabwe). Not until the 1980s and 1990s, when South African mining companies had reduced their recruitment of foreign workers and Botswana’s economic prospects had improved, were Batswana increasingly able to find job opportunities at home.

Most Batswana prefer life in their home country and choose cross-border migration on a temporary basis only for work, shopping, visiting family, or tourism. Since the 1970s, Botswana has pursued an open migration policy enabling it to recruit thousands of foreign workers to fill skilled labor shortages. In the late 1990s, Botswana’s prosperity and political stability attracted not only skilled workers but small numbers of refugees from neighboring Angola, Namibia, and Zimbabwe.

Brazil's rapid fertility decline since the 1960s is the main factor behind the country's slowing population growth rate, aging population, and fast-paced demographic transition. Brasilia has not taken full advantage of its large working-age population to develop its human capital and strengthen its social and economic institutions but is funding a study abroad program to bring advanced skills back to the country. The current favorable age structure will begin to shift around 2025, with the labor force shrinking and the elderly starting to compose an increasing share of the total population. Well-funded public pensions have nearly wiped out poverty among the elderly, and Bolsa Familia and other social programs have lifted tens of millions out of poverty. More than half of Brazil's population is considered middle class, but poverty and income inequality levels remain high; the Northeast, North, and Center-West, women, and black, mixed race, and indigenous populations are disproportionately affected. Disparities in opportunities foster social exclusion and contribute to Brazil's high crime rate, particularly violent crime in cities and favelas (slums).

Brazil has traditionally been a net recipient of immigrants, with its southeast being the prime destination. After the importation of African slaves was outlawed in the mid-19th century, Brazil sought Europeans (Italians, Portuguese, Spaniards, and Germans) and later Asians (Japanese) to work in agriculture, especially coffee cultivation. Recent immigrants come mainly from Argentina, Chile, and Andean countries (many are unskilled illegal migrants) or are returning Brazilian nationals. Since Brazil's economic downturn in the 1980s, emigration to the United States, Europe, and Japan has been rising but is negligible relative to Brazil's total population. The majority of these emigrants are well-educated and middle-class. Fewer Brazilian peasants are emigrating to neighboring countries to take up agricultural work.

Burkina Faso has a young age structure – the result of declining mortality combined with steady high fertility – and continues to experience rapid population growth, which is putting increasing pressure on the country’s limited arable land. More than 65% of the population is under the age of 25, and the population is growing at 3% annually. Mortality rates, especially those of infants and children, have decreased because of improved health care, hygiene, and sanitation, but women continue to have an average of almost 6 children. Even if fertility were substantially reduced, today’s large cohort entering their reproductive years would sustain high population growth for the foreseeable future. Only about a third of the population is literate and unemployment is widespread, dampening the economic prospects of Burkina Faso’s large working-age population.

Migration has traditionally been a way of life for Burkinabe, with seasonal migration being replaced by stints of up to two years abroad. Cote d’Ivoire remains the top destination, although it has experienced periods of internal conflict. Under French colonization, Burkina Faso became a main labor source for agricultural and factory work in Cote d’Ivoire. Burkinabe also migrated to Ghana, Mali, and Senegal for work between the world wars. Burkina Faso attracts migrants from Cote d’Ivoire, Ghana, and Mali, who often share common ethnic backgrounds with the Burkinabe. Despite its food shortages and high poverty rate, Burkina Faso has become a destination for refugees in recent years and hosts about 33,500 Malians as of May 2017.

Burundi is a densely populated country with a high population growth rate, factors that combined with land scarcity and poverty place a large share of its population at risk of food insecurity. About 90% of the population relies on subsistence agriculture. Subdivision of land to sons, and redistribution to returning refugees, results in smaller, overworked, and less productive plots. Food shortages, poverty, and a lack of clean water contribute to a 60% chronic malnutrition rate among children. A lack of reproductive health services has prevented a significant reduction in Burundi’s maternal mortality and fertility rates, which are both among the world’s highest. With two-thirds of its population under the age of 25 and a birth rate of about 6 children per woman, Burundi’s population will continue to expand rapidly for decades to come, putting additional strain on a poor country.

Historically, migration flows into and out of Burundi have consisted overwhelmingly of refugees from violent conflicts. In the last decade, more than a half million Burundian refugees returned home from neighboring countries, mainly Tanzania. Reintegrating the returnees has been problematic due to their prolonged time in exile, land scarcity, poor infrastructure, poverty, and unemployment. Repatriates and existing residents (including internally displaced persons) compete for limited land and other resources. To further complicate matters, international aid organizations reduced their assistance because they no longer classified Burundi as a post-conflict country. Conditions have deteriorated since renewed violence erupted in April 2015, causing another outpouring of refugees. In addition to refugee out-migration, Burundi has hosted thousands of refugees from neighboring countries, mostly from the Democratic Republic of the Congo and lesser numbers from Rwanda.

Cabo Verde’s population descends from its first permanent inhabitants in the late 15th-century – a preponderance of West African slaves, a small share of Portuguese colonists, and even fewer Italians, Spaniards, and Portuguese Jews. Over the centuries, the country’s overall population size has fluctuated significantly, as recurring periods of famine and epidemics have caused high death tolls and emigration.

Labor migration historically reduced Cabo Verde’s population growth and still provides a key source of income through remittances. Expatriates probably outnumber Cabo Verde’s resident population, with most families having a member abroad. Cabo Verdeans have settled in the US, Europe, Africa, and South America. The largest diaspora community in New Bedford, Massachusetts, dating to the early 1800s, is a byproduct of the transatlantic whaling industry. Cabo Verdean men fleeing poverty at home joined the crews of US whaling ships that stopped in the islands. Many settled in New Bedford and stayed in the whaling or shipping trade, worked in the textile or cranberry industries, or operated their own transatlantic packet ships that transported compatriots to the US. Increased Cabo Verdean emigration to the US coincided with the gradual and eventually complete abolition of slavery in the archipelago in 1878.

During the same period, Portuguese authorities coerced Cabo Verdeans to go to Sao Tome and Principe and other Portuguese colonies in Africa to work as indentured laborers on plantations. In the 1920s, when the US implemented immigration quotas, Cabo Verdean emigration shifted toward Portugal, West Africa (Senegal), and South America (Argentina). Growing numbers of Cabo Verdean labor migrants headed to Western Europe in the 1960s and 1970s. They filled unskilled jobs in Portugal, as many Portuguese sought out work opportunities in the more prosperous economies of northwest Europe. Cabo Verdeans eventually expanded their emigration to the Netherlands, where they worked in the shipping industry. Migration to the US resumed under relaxed migration laws. Cabo Verdean women also began migrating to southern Europe to become domestic workers, a trend that continues today and has shifted the gender balance of Cabo Verdean emigration.

Emigration has declined in more recent decades due to the adoption of more restrictive migration policies in destination countries. Reduced emigration along with a large youth population, decreased mortality rates, and increased life expectancies, has boosted population growth, putting further pressure on domestic employment and resources. In addition, Cabo Verde has attracted increasing numbers of migrants in recent decades, consisting primarily of people from West Africa, Portuguese-speaking African countries, Portugal, and China. Since the 1990s, some West African migrants have used Cabo Verde as a stepping stone for illegal migration to Europe.

Cameroon has a large youth population, with more than 60% of the populace under the age of 25. Fertility is falling but remains at a high level, especially among poor, rural, and uneducated women, in part because of inadequate access to contraception. Life expectancy remains low at about 55 years due to the prevalence of HIV and AIDs and an elevated maternal mortality rate, which has remained high since 1990. Cameroon, particularly the northern region, is vulnerable to food insecurity largely because of government mismanagement, corruption, high production costs, inadequate infrastructure, and natural disasters. Despite economic growth in some regions, poverty is on the rise, and is most prevalent in rural areas, which are especially affected by a shortage of jobs, declining incomes, poor school and health care infrastructure, and a lack of clean water and sanitation. Underinvestment in social safety nets and ineffective public financial management also contribute to Cameroon’s high rate of poverty.

International migration has been driven by unemployment (including fewer government jobs), poverty, the search for educational opportunities, and corruption. The US and Europe are preferred destinations, but, with tighter immigration restrictions in these countries, young Cameroonians are increasingly turning to neighboring states, such as Gabon and Nigeria, South Africa, other parts of Africa, and the Near and Far East. Cameroon’s limited resources make it dependent on UN support to host more than 320,000 refugees and asylum seekers as of September 2017. These refugees and asylum seekers are primarily from the Central African Republic and more recently Nigeria.

The Central African Republic’s (CAR) humanitarian crisis has worsened since a coup in March 2013. CAR’s high mortality rate and low life expectancy are attributed to elevated rates of preventable and treatable diseases (including malaria and malnutrition), an inadequate health care system, precarious food security, and armed conflict. Some of the worst mortality rates are in western CAR’s diamond mining region, which is impoverished because of government attempts to control the diamond trade and the fall in industrial diamond prices. To make matters worse, the government and international donors have reduced health funding in recent years. The CAR’s weak educational system and low literacy rate have also suffered as a result of the country’s ongoing conflict. Schools are closed, qualified teachers are scarce, infrastructure, funding, and supplies are lacking and subject to looting, and many students and teachers are displaced by violence.

Rampant poverty, human rights violations, unemployment, poor infrastructure, and a lack of security and stability have led to forced displacement internally and externally. Since the political crisis that resulted in CAR’s March 2013 coup began in December 2012, approximately 370,000 people have fled to Chad, the Democratic Republic of the Congo (DRC), and other neighboring countries, while more than an estimated 600,000 are displaced internally as of October 2017. The UN has urged countries to refrain from repatriating CAR refugees amid the heightened lawlessness.

Despite the start of oil production in 2003, 40% of Chad’s population lives below the poverty line. The population will continue to grow rapidly because of the country’s very high fertility rate and large youth cohort – more than 65% of the populace is under the age of 25 – although the mortality rate is high and life expectancy is low. Chad has the world’s third highest maternal mortality rate. Among the primary risk factors are poverty, anemia, rural habitation, high fertility, poor education, and a lack of access to family planning and obstetric care. Impoverished, uneducated adolescents living in rural areas are most affected. To improve women’s reproductive health and reduce fertility, Chad will need to increase women’s educational attainment, job participation, and knowledge of and access to family planning. Only about a quarter of women are literate, less than 5% use contraceptives, and more than 40% undergo genital cutting.

As of October 2017, more than 320,000 refugees from Sudan and more than 75,000 from the Central African Republic strain Chad’s limited resources and create tensions in host communities. Thousands of new refugees fled to Chad in 2013 to escape worsening violence in the Darfur region of Sudan. The large refugee populations are hesitant to return to their home countries because of continued instability. Chad was relatively stable in 2012 in comparison to other states in the region, but past fighting between government forces and opposition groups and inter-communal violence have left nearly 60,000 of its citizens displaced in the eastern part of the country.

Chile is in the advanced stages of demographic transition and is becoming an aging society - with fertility below replacement level, low mortality rates, and life expectancy on par with developed countries. Nevertheless, with its dependency ratio nearing its low point, Chile could benefit from its favorable age structure. It will need to keep its large working-age population productively employed, while preparing to provide for the needs of its growing proportion of elderly people, especially as women - the traditional caregivers - increasingly enter the workforce. Over the last two decades, Chile has made great strides in reducing its poverty rate, which is now lower than most Latin American countries. However, its severe income inequality ranks as the worst among members of the Organization for Economic Cooperation and Development. Unequal access to quality education perpetuates this uneven income distribution.

Chile has historically been a country of emigration but has slowly become more attractive to immigrants since transitioning to democracy in 1990 and improving its economic stability (other regional destinations have concurrently experienced deteriorating economic and political conditions). Most of Chile's small but growing foreign-born population consists of transplants from other Latin American countries, especially Peru.

Colombia is in the midst of a demographic transition resulting from steady declines in its fertility, mortality, and population growth rates. The birth rate has fallen from more than 6 children per woman in the 1960s to just above replacement level today as a result of increased literacy, family planning services, and urbanization. However, income inequality is among the worst in the world, and more than a third of the population lives below the poverty line.

Colombia experiences significant legal and illegal economic emigration and refugee outflows. Large-scale labor emigration dates to the 1960s; the United States and, until recently, Venezuela have been the main host countries. Emigration to Spain picked up in the 1990s because of its economic growth, but this flow has since diminished because of Spain’s ailing economy and high unemployment. Colombia has been the largest source of Latin American refugees in Latin America, nearly 400,000 of whom live primarily in Venezuela and Ecuador. Venezuela’s political and economic crisis since 2015, however, has created a reverse flow, consisting largely of Colombians returning home.

Forced displacement continues to be prevalent because of violence among guerrillas, paramilitary groups, and Colombian security forces. Afro-Colombian and indigenous populations are disproportionately affected. Even with the Colombian Government’s December 2016 peace agreement with the Revolutionary Armed Forces of Colombia (FARC), the risk of displacement remains as other rebel groups fill the void left by the FARC. Between 1985 and September 2017, nearly 7.6 million persons have been internally displaced, the highest total in the world. These estimates may undercount actual numbers because many internally displaced persons are not registered. Historically, Colombia also has one of the world’s highest levels of forced disappearances. About 30,000 cases have been recorded over the last four decades—although the number is likely to be much higher—including human rights activists, trade unionists, Afro-Colombians, indigenous people, and farmers in rural conflict zones.

Because of political violence and economic problems, Colombia received limited numbers of immigrants during the 19th and 20th centuries, mostly from the Middle East, Europe, and Japan. More recently, growth in the oil, mining, and manufacturing sectors has attracted increased labor migration; the primary source countries are Venezuela, the US, Mexico, and Argentina. Colombia has also become a transit area for illegal migrants from Africa, Asia, and the Caribbean -- especially Haiti and Cuba -- who are en route to the US or Canada.

Comoros’ population is a melange of Arabs, Persians, Indonesians, Africans, and Indians, and the much smaller number of Europeans that settled on the islands between the 8th and 19th centuries, when they served as a regional trade hub. The Arab and Persian influence is most evident in the islands’ overwhelmingly Muslim majority – about 98% of Comorans are Sunni Muslims. The country is densely populated, averaging nearly 350 people per square mile, although this varies widely among the islands, with Anjouan being the most densely populated.

Given the large share of land dedicated to agriculture and Comoros’ growing population, habitable land is becoming increasingly crowded. The combination of increasing population pressure on limited land and resources, widespread poverty, and poor job prospects motivates thousands of Comorans each year to attempt to illegally migrate using small fishing boats to the neighboring island of Mayotte, which is a French territory. The majority of legal Comoran migration to France came after Comoros’ independence from France in 1975, with the flow peaking in the mid-1980s.

At least 150,000 to 200,000 people of Comoran citizenship or descent live abroad, mainly in France, where they have gone seeking a better quality of life, job opportunities, higher education (Comoros has no universities), advanced health care, and to finance elaborate traditional wedding ceremonies (aada). Remittances from the diaspora are an economic mainstay, in 2013 representing approximately 25% of Comoros’ GDP and significantly more than the value of its exports of goods and services (only 15% of GDP). Grand Comore, Comoros’ most populous island, is both the primary source of emigrants and the main recipient of remittances. Most remittances are spent on private consumption, but this often goes toward luxury goods and the aada and does not contribute to economic development or poverty reduction. Although the majority of the diaspora is now French-born with more distant ties to Comoros, it is unclear whether they will sustain the current level of remittances.

Despite a wealth of fertile soil, hydroelectric power potential, and mineral resources, the Democratic Republic of the Congo (DRC) struggles with many socioeconomic problems, including high infant and maternal mortality rates, malnutrition, poor vaccination coverage, lack of access to improved water sources and sanitation, and frequent and early fertility. Ongoing conflict, mismanagement of resources, and a lack of investment have resulted in food insecurity; almost 30 percent of children under the age of 5 are malnourished. The overall coverage of basic public services – education, health, sanitation, and potable water – is very limited and piecemeal, with substantial regional and rural/urban disparities. Fertility remains high at almost 5 children per woman and is likely to remain high because of the low use of contraception and the cultural preference for larger families.

The DRC is a source and host country for refugees. Between 2012 and 2014, more than 119,000 Congolese refugees returned from the Republic of Congo to the relative stability of northwest DRC, but more than 540,000 Congolese refugees remained abroad as of year-end 2015. In addition, an estimated 3.9 million Congolese were internally displaced as of October 2017, the vast majority fleeing violence between rebel group and Congolese armed forces. Thousands of refugees have come to the DRC from neighboring countries, including Rwanda, the Central African Republic, and Burundi.

Costa Rica's political stability, high standard of living, and well-developed social benefits system set it apart from its Central American neighbors. Through the government's sustained social spending - almost 20% of GDP annually - Costa Rica has made tremendous progress toward achieving its goal of providing universal access to education, healthcare, clean water, sanitation, and electricity. Since the 1970s, expansion of these services has led to a rapid decline in infant mortality, an increase in life expectancy at birth, and a sharp decrease in the birth rate. The average number of children born per women has fallen from about 7 in the 1960s to 3.5 in the early 1980s to below replacement level today. Costa Rica's poverty rate is lower than in most Latin American countries, but it has stalled at around 20% for almost two decades.

Costa Rica is a popular regional immigration destination because of its job opportunities and social programs. Almost 9% of the population is foreign-born, with Nicaraguans comprising nearly three-quarters of the foreign population. Many Nicaraguans who perform unskilled seasonal labor enter Costa Rica illegally or overstay their visas, which continues to be a source of tension. Less than 3% of Costa Rica's population lives abroad. The overwhelming majority of expatriates have settled in the United States after completing a university degree or in order to work in a highly skilled field.

Cote d’Ivoire’s population is likely to continue growing for the foreseeable future because almost 60% of the populace is younger than 25, the total fertility rate is holding steady at about 3.5 children per woman, and contraceptive use is under 20%. The country will need to improve education, health care, and gender equality in order to turn its large and growing youth cohort into human capital. Even prior to 2010 unrest that shuttered schools for months, access to education was poor, especially for women. As of 2015, only 53% of men and 33% of women were literate. The lack of educational attainment contributes to Cote d’Ivoire’s high rates of unskilled labor, adolescent pregnancy, and HIV/AIDS prevalence.

Following its independence in 1960, Cote d’Ivoire’s stability and the blossoming of its labor-intensive cocoa and coffee industries in the southwest made it an attractive destination for migrants from other parts of the country and its neighbors, particularly Burkina Faso. The HOUPHOUET-BOIGNY administration continued the French colonial policy of encouraging labor immigration by offering liberal land ownership laws. Foreigners from West Africa, Europe (mainly France), and Lebanon composed about 25% of the population by 1998.

Ongoing economic decline since the 1980s and the power struggle after HOUPHOUET-BOIGNY’s death in 1993 ushered in the politics of "Ivoirite," institutionalizing an Ivoirian identity that further marginalized northern Ivoirians and scapegoated immigrants. The hostile Muslim north-Christian south divide snowballed into a 2002 civil war, pushing tens of thousands of foreign migrants, Liberian refugees, and Ivoirians to flee to war-torn Liberia or other regional countries and more than a million people to be internally displaced. Subsequently, violence following the contested 2010 presidential election prompted some 250,000 people to seek refuge in Liberia and other neighboring countries and again internally displaced as many as a million people. By July 2012, the majority had returned home, but ongoing inter-communal tension and armed conflict continue to force people from their homes.

Djibouti is a poor, predominantly urban country, characterized by high rates of illiteracy, unemployment, and childhood malnutrition. More than 75% of the population lives in cities and towns (predominantly in the capital, Djibouti). The rural population subsists primarily on nomadic herding. Prone to droughts and floods, the country has few natural resources and must import more than 80% of its food from neighboring countries or Europe. Health care, particularly outside the capital, is limited by poor infrastructure, shortages of equipment and supplies, and a lack of qualified personnel. More than a third of health care recipients are migrants because the services are still better than those available in their neighboring home countries. The nearly universal practice of female genital cutting reflects Djibouti’s lack of gender equality and is a major contributor to obstetrical complications and its high rates of maternal and infant mortality. A 1995 law prohibiting the practice has never been enforced.

Because of its political stability and its strategic location at the confluence of East Africa and the Gulf States along the Gulf of Aden and the Red Sea, Djibouti is a key transit point for migrants and asylum seekers heading for the Gulf States and beyond. Each year some hundred thousand people, mainly Ethiopians and some Somalis, journey through Djibouti, usually to the port of Obock, to attempt a dangerous sea crossing to Yemen. However, with the escalation of the ongoing Yemen conflict, Yemenis began fleeing to Djibouti in March 2015, with almost 20,000 arriving by August 2017. Most Yemenis remain unregistered and head for Djibouti City rather than seeking asylum at one of Djibouti’s three spartan refugee camps. Djibouti has been hosting refugees and asylum seekers, predominantly Somalis and lesser numbers of Ethiopians and Eritreans, at camps for 20 years, despite lacking potable water, food shortages, and unemployment.

Ecuador's high poverty and income inequality most affect indigenous, mixed race, and rural populations. The government has increased its social spending to ameliorate these problems, but critics question the efficiency and implementation of its national development plan. Nevertheless, the conditional cash transfer program, which requires participants' children to attend school and have medical check-ups, has helped improve educational attainment and healthcare among poor children. Ecuador is stalled at above replacement level fertility and the population most likely will keep growing rather than stabilize.

An estimated 2 to 3 million Ecuadorians live abroad, but increased unemployment in key receiving countries - Spain, the United States, and Italy - is slowing emigration and increasing the likelihood of returnees to Ecuador. The first large-scale emigration of Ecuadorians occurred between 1980 and 2000, when an economic crisis drove Ecuadorians from southern provinces to New York City, where they had trade contacts. A second, nationwide wave of emigration in the late 1990s was caused by another economic downturn, political instability, and a currency crisis. Spain was the logical destination because of its shared language and the wide availability of low-skilled, informal jobs at a time when increased border surveillance made illegal migration to the US difficult. Ecuador has a small but growing immigrant population and is Latin America's top recipient of refugees; 98% are neighboring Colombians fleeing violence in their country.

Egypt is the most populous country in the Arab world and the third most populous country in Africa, behind Nigeria and Ethiopia. Most of the country is desert, so about 95% of the population is concentrated in a narrow strip of fertile land along the Nile River, which represents only about 5% of Egypt’s land area. Egypt’s rapid population growth – 46% between 1994 and 2014 – stresses limited natural resources, jobs, housing, sanitation, education, and health care.

Although the country’s total fertility rate (TFR) fell from roughly 5.5 children per woman in 1980 to just over 3 in the late 1990s, largely as a result of state-sponsored family planning programs, the population growth rate dropped more modestly because of decreased mortality rates and longer life expectancies. During the last decade, Egypt’s TFR decline stalled for several years and then reversed, reaching 3.6 in 2011, and has plateaued the last few years. Contraceptive use has held steady at about 60%, while preferences for larger families and early marriage may have strengthened in the wake of the recent 2011 revolution. The large cohort of women of or nearing childbearing age will sustain high population growth for the foreseeable future (an effect called population momentum).

Nevertheless, post-MUBARAK governments have not made curbing population growth a priority. To increase contraceptive use and to prevent further overpopulation will require greater government commitment and substantial social change, including encouraging smaller families and better educating and empowering women. Currently, literacy, educational attainment, and labor force participation rates are much lower for women than men. In addition, the prevalence of violence against women, the lack of female political representation, and the perpetuation of the nearly universal practice of female genital cutting continue to keep women from playing a more significant role in Egypt’s public sphere.

Population pressure, poverty, high unemployment, and the fragmentation of inherited land holdings have historically motivated Egyptians, primarily young men, to migrate internally from rural and smaller urban areas in the Nile Delta region and the poorer rural south to Cairo, Alexandria, and other urban centers in the north, while a much smaller number migrated to the Red Sea and Sinai areas. Waves of forced internal migration also resulted from the 1967 Arab-Israeli War and the floods caused by the completion of the Aswan High Dam in 1970. Limited numbers of students and professionals emigrated temporarily prior to the early 1970s, when economic problems and high unemployment pushed the Egyptian Government to lift restrictions on labor migration. At the same time, high oil revenues enabled Saudi Arabia, Iraq, and other Gulf states, as well as Libya and Jordan, to fund development projects, creating a demand for unskilled labor (mainly in construction), which attracted tens of thousands of young Egyptian men.

Between 1970 and 1974 alone, Egyptian migrants in the Gulf countries increased from approximately 70,000 to 370,000. Egyptian officials encouraged legal labor migration both to alleviate unemployment and to generate remittance income (remittances continue to be one of Egypt’s largest sources of foreign currency and GDP). During the mid-1980s, however, depressed oil prices resulting from the Iran-Iraq War, decreased demand for low-skilled labor, competition from less costly South Asian workers, and efforts to replace foreign workers with locals significantly reduced Egyptian migration to the Gulf States. The number of Egyptian migrants dropped from a peak of almost 3.3 million in 1983 to about 2.2 million at the start of the 1990s, but numbers gradually recovered.

In the 2000s, Egypt began facilitating more labor migration through bilateral agreements, notably with Arab countries and Italy, but illegal migration to Europe through overstayed visas or maritime human smuggling via Libya also rose. The Egyptian Government estimated there were 6.5 million Egyptian migrants in 2009, with roughly 75% being temporary migrants in other Arab countries (Libya, Saudi Arabia, Jordan, Kuwait, and the United Arab Emirates) and 25% being predominantly permanent migrants in the West (US, UK, Italy, France, and Canada).

During the 2000s, Egypt became an increasingly important transit and destination country for economic migrants and asylum seekers, including Palestinians, East Africans, and South Asians and, more recently, Iraqis and Syrians. Egypt draws many refugees because of its resettlement programs with the West; Cairo has one of the largest urban refugee populations in the world. Many East African migrants are interned or live in temporary encampments along the Egypt-Israel border, and some have been shot and killed by Egyptian border guards.

El Salvador is the smallest and most densely populated country in Central America. It is well into its demographic transition, experiencing slower population growth, a decline in its number of youths, and the gradual aging of its population. The increased use of family planning has substantially lowered El Salvador's fertility rate, from approximately 6 children per woman in the 1970s to replacement level today. A 2008 national family planning survey showed that female sterilization remained the most common contraception method in El Salvador - its sterilization rate is among the highest in Latin America and the Caribbean - but that the use of injectable contraceptives is growing. Fertility differences between rich and poor and urban and rural women are narrowing.

Salvadorans fled during the 1979 to 1992 civil war mainly to the United States but also to Canada and to neighboring Mexico, Guatemala, Honduras, Nicaragua, and Costa Rica. Emigration to the United States increased again in the 1990s and 2000s as a result of deteriorating economic conditions, natural disasters (Hurricane Mitch in 1998 and earthquakes in 2001), and family reunification. At least 20% of El Salvador's population lives abroad. The remittances they send home account for close to 20% of GDP, are the second largest source of external income after exports, and have helped reduce poverty.

Equatorial Guinea is one of the smallest and least populated countries in continental Africa and is the only independent African country where Spanish is an official language. Despite a boom in oil production in the 1990s, authoritarianism, corruption, and resource mismanagement have concentrated the benefits among a small elite. These practices have perpetuated income inequality and unbalanced development, such as low public spending on education and health care. Unemployment remains problematic because the oil-dominated economy employs a small labor force dependent on skilled foreign workers. The agricultural sector, Equatorial Guinea’s main employer, continues to deteriorate because of a lack of investment and the migration of rural workers to urban areas. About three-quarters of the population lives below the poverty line.

Equatorial Guinea’s large and growing youth population – about 60% are under the age of 25 – is particularly affected because job creation in the non-oil sectors is limited, and young people often do not have the skills needed in the labor market. Equatorial Guinean children frequently enter school late, have poor attendance, and have high dropout rates. Thousands of Equatorial Guineans fled across the border to Gabon in the 1970s to escape the dictatorship of MACIAS NGUEMA; smaller numbers have followed in the decades since. Continued inequitable economic growth and high youth unemployment increases the likelihood of ethnic and regional violence.

Eritrea is a persistently poor country that has made progress in some socioeconomic categories but not in others. Education and human capital formation are national priorities for facilitating economic development and eradicating poverty. To this end, Eritrea has made great strides in improving adult literacy – doubling the literacy rate over the last 20 years – in large part because of its successful adult education programs. The overall literacy rate was estimated to be almost 74% in 2015; more work needs to be done to raise female literacy and school attendance among nomadic and rural communities. Subsistence farming fails to meet the needs of Eritrea’s growing population because of repeated droughts, dwindling arable land, overgrazing, soil erosion, and a shortage of farmers due to conscription and displacement. The government’s emphasis on spending on defense over agriculture and its lack of foreign exchange to import food also contribute to food insecurity.

Eritrea has been a leading refugee source country since at least the 1960s, when its 30-year war for independence from Ethiopia began. Since gaining independence in 1993, Eritreans have continued migrating to Sudan, Ethiopia, Yemen, Egypt, or Israel because of a lack of basic human rights or political freedom, educational and job opportunities, or to seek asylum because of militarization. Eritrea’s large diaspora has been a source of vital remittances, funding its war for independence and providing 30% of the country’s GDP annually since it became independent.

In the last few years, Eritreans have increasingly been trafficked and held hostage by Bedouins in the Sinai Desert, where they are victims of organ harvesting, rape, extortion, and torture. Some Eritrean trafficking victims are kidnapped after being smuggled to Sudan or Ethiopia, while others are kidnapped from within or around refugee camps or crossing Eritrea’s borders. Eritreans composed approximately 90% of the conservatively estimated 25,000-30,000 victims of Sinai trafficking from 2009-2013, according to a 2013 consultancy firm report.

Eswatini, a small, predominantly rural, landlocked country surrounded by South Africa and Mozambique, suffers from severe poverty and the world’s highest HIV/AIDS prevalence rate. A weak and deteriorating economy, high unemployment, rapid population growth, and an uneven distribution of resources all combine to worsen already persistent poverty and food insecurity, especially in rural areas. Erratic weather (frequent droughts and intermittent heavy rains and flooding), overuse of small plots, the overgrazing of cattle, and outdated agricultural practices reduce crop yields and further degrade the environment, exacerbating Eswatini's poverty and subsistence problems. Eswatini's extremely high HIV/AIDS prevalence rate – more than 28% of adults have the disease – compounds these issues. Agricultural production has declined due to HIV/AIDS, as the illness causes households to lose manpower and to sell livestock and other assets to pay for medicine and funerals.

Swazis, mainly men from the country’s rural south, have been migrating to South Africa to work in coal, and later gold, mines since the late 19th century. Although the number of miners abroad has never been high in absolute terms because of Eswatini's small population, the outflow has had important social and economic repercussions. The peak of mining employment in South Africa occurred during the 1980s. Cross-border movement has accelerated since the 1990s, as increasing unemployment has pushed more Swazis to look for work in South Africa (creating a "brain drain" in the health and educational sectors); southern Swazi men have continued to pursue mining, although the industry has downsized. Women now make up an increasing share of migrants and dominate cross-border trading in handicrafts, using the proceeds to purchase goods back in Eswatini. Much of today’s migration, however, is not work-related but focuses on visits to family and friends, tourism, and shopping.

Ethiopia is a predominantly agricultural country – more than 80% of the population lives in rural areas – that is in the early stages of demographic transition. Infant, child, and maternal mortality have fallen sharply over the past decade, but the total fertility rate has declined more slowly and the population continues to grow. The rising age of marriage and the increasing proportion of women remaining single have contributed to fertility reduction. While the use of modern contraceptive methods among married women has increased significantly from 6 percent in 2000 to 27 percent in 2012, the overall rate is still quite low.

Ethiopia’s rapid population growth is putting increasing pressure on land resources, expanding environmental degradation, and raising vulnerability to food shortages. With more than 40 percent of the population below the age of 15 and a fertility rate of over 5 children per woman (and even higher in rural areas), Ethiopia will have to make further progress in meeting its family planning needs if it is to achieve the age structure necessary for reaping a demographic dividend in the coming decades.

Poverty, drought, political repression, and forced government resettlement have driven Ethiopia’s internal and external migration since the 1960s. Before the 1974 revolution, only small numbers of the Ethiopian elite went abroad to study and then returned home, but under the brutal Derg regime thousands fled the country, primarily as refugees. Between 1982 and 1991 there was a new wave of migration to the West for family reunification. Since the defeat of the Derg in 1991, Ethiopians have migrated to escape violence among some of the country’s myriad ethnic groups or to pursue economic opportunities. Internal and international trafficking of women and children for domestic work and prostitution is a growing problem.

Gabon’s oil revenues have given it one of the highest per capita income levels in sub-Saharan Africa, but the wealth is not evenly distributed and poverty is widespread. Unemployment is especially prevalent among the large youth population; more than 60% of the population is under the age of 25. With a fertility rate still averaging more than 4 children per woman, the youth population will continue to grow and further strain the mismatch between Gabon’s supply of jobs and the skills of its labor force.

Gabon has been a magnet to migrants from neighboring countries since the 1960s because of the discovery of oil, as well as the country’s political stability and timber, mineral, and natural gas resources. Nonetheless, income inequality and high unemployment have created slums in Libreville full of migrant workers from Senegal, Nigeria, Cameroon, Benin, Togo, and elsewhere in West Africa. In 2011, Gabon declared an end to refugee status for 9,500 remaining Congolese nationals to whom it had granted asylum during the Republic of the Congo’s civil war between 1997 and 2003. About 5,400 of these refugees received permits to reside in Gabon.

The Gambia’s youthful age structure – almost 60% of the population is under the age of 25 – is likely to persist because the country’s total fertility rate remains strong at nearly 4 children per woman. The overall literacy rate is around 55%, and is significantly lower for women than for men. At least 70% of the populace are farmers who are reliant on rain-fed agriculture and cannot afford improved seeds and fertilizers. Crop failures caused by droughts between 2011 and 2013 have increased poverty, food shortages, and malnutrition.

The Gambia is a source country for migrants and a transit and destination country for migrants and refugees. Since the 1980s, economic deterioration, drought, and high unemployment, especially among youths, have driven both domestic migration (largely urban) and migration abroad (legal and illegal). Emigrants are largely skilled workers, including doctors and nurses, and provide a significant amount of remittances. The top receiving countries for Gambian emigrants are Spain, the US, Nigeria, Senegal, and the UK. While the Gambia and Spain do not share historic, cultural, or trade ties, rural Gambians have migrated to Spain in large numbers because of its proximity and the availability of jobs in its underground economy (this flow slowed following the onset of Spain’s late 2007 economic crisis).

The Gambia’s role as a host country to refugees is a result of wars in several of its neighboring West African countries. Since 2006, refugees from the Casamance conflict in Senegal have replaced their pattern of flight and return with permanent settlement in The Gambia, often moving in with relatives along the Senegal-Gambia border. The strain of providing for about 7,400 Casamance refugees has increased poverty among Gambian villagers.

Ghana has a young age structure, with approximately 57% of the population under the age of 25. Its total fertility rate fell significantly during the 1980s and 1990s but has stalled at around four children per woman for the last few years. Fertility remains higher in the northern region than the Greater Accra region. On average, desired fertility has remained stable for several years; urban dwellers want fewer children than rural residents. Increased life expectancy, due to better health care, nutrition, and hygiene, and reduced fertility have increased Ghana’s share of elderly persons; Ghana’s proportion of persons aged 60+ is among the highest in sub-Saharan Africa. Poverty has declined in Ghana, but it remains pervasive in the northern region, which is susceptible to droughts and floods and has less access to transportation infrastructure, markets, fertile farming land, and industrial centers. The northern region also has lower school enrollment, higher illiteracy, and fewer opportunities for women.

Ghana was a country of immigration in the early years after its 1957 independence, attracting labor migrants largely from Nigeria and other neighboring countries to mine minerals and harvest cocoa – immigrants composed about 12% of Ghana’s population in 1960. In the late 1960s, worsening economic and social conditions discouraged immigration, and hundreds of thousands of immigrants, mostly Nigerians, were expelled.

During the 1970s, severe drought and an economic downturn transformed Ghana into a country of emigration; neighboring Cote d’Ivoire was the initial destination. Later, hundreds of thousands of Ghanaians migrated to Nigeria to work in its booming oil industry, but most were deported in 1983 and 1985 as oil prices plummeted. Many Ghanaians then turned to more distant destinations, including other parts of Africa, Europe, and North America, but the majority continued to migrate within West Africa. Since the 1990s, increased emigration of skilled Ghanaians, especially to the US and the UK, drained the country of its health care and education professionals. Internally, poverty and other developmental disparities continue to drive Ghanaians from the north to the south, particularly to its urban centers.

Guatemala is a predominantly poor country that struggles in several areas of health and development, including infant, child, and maternal mortality, malnutrition, literacy, and contraceptive awareness and use. The country's large indigenous population is disproportionately affected. Guatemala is the most populous country in Central America and has the highest fertility rate in Latin America. It also has the highest population growth rate in Latin America, which is likely to continue because of its large reproductive-age population and high birth rate. Almost half of Guatemala's population is under age 19, making it the youngest population in Latin America. Guatemala's total fertility rate has slowly declined during the last few decades due in part to limited government-funded health programs. However, the birth rate is still more close to three children per woman and is markedly higher among its rural and indigenous populations.

Guatemalans have a history of emigrating legally and illegally to Mexico, the United States, and Canada because of a lack of economic opportunity, political instability, and natural disasters. Emigration, primarily to the United States, escalated during the 1960 to 1996 civil war and accelerated after a peace agreement was signed. Thousands of Guatemalans who fled to Mexico returned after the war, but labor migration to southern Mexico continues.

Guinea’s strong population growth is a result of declining mortality rates and sustained elevated fertility. The population growth rate was somewhat tempered in the 2000s because of a period of net outmigration. Although life expectancy and mortality rates have improved over the last two decades, the nearly universal practice of female genital cutting continues to contribute to high infant and maternal mortality rates. Guinea’s total fertility remains high at about 5 children per woman because of the ongoing preference for larger families, low contraceptive usage and availability, a lack of educational attainment and empowerment among women, and poverty. A lack of literacy and vocational training programs limit job prospects for youths, but even those with university degrees often have no option but to work in the informal sector. About 60% of the country’s large youth population is unemployed.

Tensions and refugees have spilled over Guinea’s borders with Sierra Leone, Liberia, and Cote d’Ivoire. During the 1990s Guinea harbored as many as half a million refugees from Sierra Leone and Liberia, more refugees than any other African country for much of that decade. About half sought refuge in the volatile "Parrot’s Beak" region of southwest Guinea, a wedge of land jutting into Sierra Leone near the Liberian border. Many were relocated within Guinea in the early 2000s because the area suffered repeated cross-border attacks from various government and rebel forces, as well as anti-refugee violence.

Guinea-Bissau’s young and growing population is sustained by high fertility; approximately 60% of the population is under the age of 25. Its large reproductive-age population and total fertility rate of more than 4 children per woman offsets the country’s high infant and maternal mortality rates. The latter is among the world’s highest because of the prevalence of early childbearing, a lack of birth spacing, the high percentage of births outside of health care facilities, and a shortage of medicines and supplies.

Guinea-Bissau’s history of political instability, a civil war, and several coups (the latest in 2012) have resulted in a fragile state with a weak economy, high unemployment, rampant corruption, widespread poverty, and thriving drug and child trafficking. With the country lacking educational infrastructure, school funding and materials, and qualified teachers, and with the cultural emphasis placed on religious education, parents frequently send boys to study in residential Koranic schools (daaras) in Senegal and The Gambia. They often are extremely deprived and are forced into street begging or agricultural work by marabouts (Muslim religious teachers), who enrich themselves at the expense of the children. Boys who leave their marabouts often end up on the streets of Dakar or other large Senegalese towns and are vulnerable to even worse abuse.

Some young men lacking in education and job prospects become involved in the flourishing international drug trade. Local drug use and associated violent crime are growing.

Guyana is the only English-speaking country in South America and shares cultural and historical bonds with the Anglophone Caribbean. Guyana's two largest ethnic groups are the Afro-Guyanese (descendants of African slaves) and the Indo-Guyanese (descendants of Indian indentured laborers), which together comprise about three quarters of Guyana's population. Tensions periodically have boiled over between the two groups, which back ethnically based political parties and vote along ethnic lines. Poverty reduction has stagnated since the late 1990s. About one-third of the Guyanese population lives below the poverty line; indigenous people are disproportionately affected. Although Guyana's literacy rate is reported to be among the highest in the Western Hemisphere, the level of functional literacy is considerably lower, which has been attributed to poor education quality, teacher training, and infrastructure.

Guyana's emigration rate is among the highest in the world - more than 55% of its citizens reside abroad - and it is one of the largest recipients of remittances relative to GDP among Latin American and Caribbean counties. Although remittances are a vital source of income for most citizens, the pervasive emigration of skilled workers deprives Guyana of professionals in healthcare and other key sectors. More than 80% of Guyanese nationals with tertiary level educations have emigrated. Brain drain and the concentration of limited medical resources in Georgetown hamper Guyana's ability to meet the health needs of its predominantly rural population. Guyana has one of the highest HIV prevalence rates in the region and continues to rely on international support for its HIV treatment and prevention programs.

Honduras is one of the poorest countries in Latin America and has one of the world's highest murder rates. More than half of the population lives in poverty and per capita income is one of the lowest in the region. Poverty rates are higher among rural and indigenous people and in the south, west, and along the eastern border than in the north and central areas where most of Honduras' industries and infrastructure are concentrated. The increased productivity needed to break Honduras' persistent high poverty rate depends, in part, on further improvements in educational attainment. Although primary-school enrollment is near 100%, educational quality is poor, the drop-out rate and grade repetition remain high, and teacher and school accountability is low.

Honduras' population growth rate has slowed since the 1990s, but it remains high at nearly 2% annually because the birth rate averages approximately three children per woman and more among rural, indigenous, and poor women. Consequently, Honduras' young adult population - ages 15 to 29 - is projected to continue growing rapidly for the next three decades and then stabilize or slowly shrink. Population growth and limited job prospects outside of agriculture will continue to drive emigration. Remittances represent about a fifth of GDP.

Kenya has experienced dramatic population growth since the mid-20th century as a result of its high birth rate and its declining mortality rate. More than 40% of Kenyans are under the age of 15 because of sustained high fertility, early marriage and childbearing, and an unmet need for family planning. Kenya’s persistent rapid population growth strains the labor market, social services, arable land, and natural resources. Although Kenya in 1967 was the first sub-Saharan country to launch a nationwide family planning program, progress in reducing the birth rate has largely stalled since the late 1990s, when the government decreased its support for family planning to focus on the HIV epidemic. Government commitment and international technical support spurred Kenyan contraceptive use, decreasing the fertility rate (children per woman) from about 8 in the late 1970s to less than 5 children twenty years later, but it has plateaued at just over 3 children today.

Kenya is a source of emigrants and a host country for refugees. In the 1960s and 1970s, Kenyans pursued higher education in the UK because of colonial ties, but as British immigration rules tightened, the US, the then Soviet Union, and Canada became attractive study destinations. Kenya’s stagnant economy and political problems during the 1980s and 1990s led to an outpouring of Kenyan students and professionals seeking permanent opportunities in the West and southern Africa. Nevertheless, Kenya’s relative stability since its independence in 1963 has attracted hundreds of thousands of refugees escaping violent conflicts in neighboring countries; Kenya shelters more than 300,000 Somali refugees as of April 2017.

Lesotho faces great socioeconomic challenges. More than half of its population lives below the property line, and the country’s HIV/AIDS prevalence rate is the second highest in the world. In addition, Lesotho is a small, mountainous, landlocked country with little arable land, leaving its population vulnerable to food shortages and reliant on remittances. Lesotho’s persistently high infant, child, and maternal mortality rates have been increasing during the last decade, according to the last two Demographic and Health Surveys. Despite these significant shortcomings, Lesotho has made good progress in education; it is on-track to achieve universal primary education and has one of the highest adult literacy rates in Africa.

Lesotho’s migration history is linked to its unique geography; it is surrounded by South Africa with which it shares linguistic and cultural traits. Lesotho at one time had more of its workforce employed outside its borders than any other country. Today remittances equal about 17% of its GDP. With few job options at home, a high rate of poverty, and higher wages available across the border, labor migration to South Africa replaced agriculture as the prevailing Basotho source of income decades ago. The majority of Basotho migrants were single men contracted to work as gold miners in South Africa. However, migration trends changed in the 1990s, and fewer men found mining jobs in South Africa because of declining gold prices, stricter immigration policies, and a preference for South African workers.

Although men still dominate cross-border labor migration, more women are working in South Africa, mostly as domestics, because they are widows or their husbands are unemployed. Internal rural-urban flows have also become more frequent, with more women migrating within the country to take up jobs in the garment industry or moving to care for loved ones with HIV/AIDS. Lesotho’s small population of immigrants is increasingly composed of Taiwanese and Chinese migrants who are involved in the textile industry and small retail businesses.

Liberia’s high fertility rate of nearly 5 children per woman and large youth cohort – more than 60% of the population is under the age of 25 – will sustain a high dependency ratio for many years to come. Significant progress has been made in preventing child deaths, despite a lack of health care workers and infrastructure. Infant and child mortality have dropped nearly 70% since 1990; the annual reduction rate of about 5.4% is the highest in Africa.

Nevertheless, Liberia’s high maternal mortality rate remains among the world’s worst; it reflects a high unmet need for family planning services, frequency of early childbearing, lack of quality obstetric care, high adolescent fertility, and a low proportion of births attended by a medical professional. Female mortality is also increased by the prevalence of female genital cutting (FGC), which is practiced by 10 of Liberia’s 16 tribes and affects more than two-thirds of women and girls. FGC is an initiation ritual performed in rural bush schools, which teach traditional beliefs on marriage and motherhood and are an obstacle to formal classroom education for Liberian girls.

Liberia has been both a source and a destination for refugees. During Liberia’s 14-year civil war (1989-2003), more than 250,000 people became refugees and another half million were internally displaced. Between 2004 and the cessation of refugee status for Liberians in June 2012, the UNHCR helped more than 155,000 Liberians to voluntarily repatriate, while others returned home on their own. Some Liberian refugees spent more than two decades living in other West African countries. Liberia hosted more than 125,000 Ivoirian refugees escaping post-election violence in 2010-11; as of mid-2017, about 12,000 Ivoirian refugees were still living in Liberia as of October 2017 because of instability.

Despite continuing unrest, Libya remains a destination country for economic migrants. It is also a hub for transit migration to Europe because of its proximity to southern Europe and its lax border controls. Labor migrants have been drawn to Libya since the development of its oil sector in the 1960s. Until the latter part of the 1990s, most migrants to Libya were Arab (primarily Egyptians and Sudanese). However, international isolation stemming from Libya’s involvement in international terrorism and a perceived lack of support from Arab countries led QADHAFI in 1998 to adopt a decade-long pan-African policy that enabled large numbers of sub-Saharan migrants to enter Libya without visas to work in the construction and agricultural industries. Although sub-Saharan Africans provided a cheap labor source, they were poorly treated and were subjected to periodic mass expulsions.

By the mid-2000s, domestic animosity toward African migrants and a desire to reintegrate into the international community motivated QADHAFI to impose entry visas on Arab and African immigrants and to agree to joint maritime patrols and migrant repatriations with Italy, the main recipient of illegal migrants departing Libya. As his regime neared collapse in 2011, QADHAFI reversed his policy of cooperating with Italy to curb illegal migration and sent boats loaded with migrants and asylum seekers to strain European resources. Libya’s 2011 revolution decreased immigration drastically and prompted nearly 800,000 migrants to flee to third countries, mainly Tunisia and Egypt, or to their countries of origin. The inflow of migrants declined in 2012 but returned to normal levels by 2013, despite continued hostility toward sub-Saharan Africans and a less-inviting job market.

While Libya is not an appealing destination for migrants, since 2014, transiting migrants – primarily from East and West Africa – continue to exploit its political instability and weak border controls and use it as a primary departure area to migrate across the central Mediterranean to Europe in growing numbers. In addition, more than 200,000 people were displaced internally as of August 2017 by fighting between armed groups in eastern and western Libya and, to a lesser extent, by inter-tribal clashes in the country’s south.

Madagascar’s youthful population – just over 60% are under the age of 25 – and high total fertility rate of more than 4 children per women ensures that the Malagasy population will continue its rapid growth trajectory for the foreseeable future. The population is predominantly rural and poor; chronic malnutrition is prevalent, and large families are the norm. Many young Malagasy girls are withdrawn from school, marry early (often pressured to do so by their parents), and soon begin having children. Early childbearing, coupled with Madagascar’s widespread poverty and lack of access to skilled health care providers during delivery, increases the risk of death and serious health problems for young mothers and their babies.

Child marriage perpetuates gender inequality and is prevalent among the poor, the uneducated, and rural households – as of 2013, of Malagasy women aged 20 to 24, more than 40% were married and more than a third had given birth by the age of 18. Although the legal age for marriage is 18, parental consent is often given for earlier marriages or the law is flouted, especially in rural areas that make up nearly 65% of the country. Forms of arranged marriage whereby young girls are married to older men in exchange for oxen or money are traditional. If a union does not work out, a girl can be placed in another marriage, but the dowry paid to her family diminishes with each unsuccessful marriage.

Madagascar’s population consists of 18 main ethnic groups, all of whom speak the same Malagasy language. Most Malagasy are multi-ethnic, however, reflecting the island’s diversity of settlers and historical contacts (see Background). Madagascar’s legacy of hierarchical societies practicing domestic slavery (most notably the Merina Kingdom of the 16th to the 19th century) is evident today in persistent class tension, with some ethnic groups maintaining a caste system. Slave descendants are vulnerable to unequal access to education and jobs, despite Madagascar’s constitutional guarantee of free compulsory primary education and its being party to several international conventions on human rights. Historical distinctions also remain between central highlanders and coastal people.

Malawi has made great improvements in maternal and child health, but has made less progress in reducing its high fertility rate. In both rural and urban areas, very high proportions of mothers are receiving prenatal care and skilled birth assistance, and most children are being vaccinated. Malawi’s fertility rate, however, has only declined slowly, decreasing from more than 7 children per woman in the 1980s to about 5.5 today. Nonetheless, Malawians prefer smaller families than in the past, and women are increasingly using contraceptives to prevent or space pregnancies. Rapid population growth and high population density is putting pressure on Malawi’s land, water, and forest resources. Reduced plot sizes and increasing vulnerability to climate change, further threaten the sustainability of Malawi’s agriculturally based economy and will worsen food shortages. About 80% of the population is employed in agriculture.

Historically, Malawians migrated abroad in search of work, primarily to South Africa and present-day Zimbabwe, but international migration became uncommon after the 1970s, and most migration in recent years has been internal. During the colonial period, Malawians regularly migrated to southern Africa as contract farm laborers, miners, and domestic servants. In the decade and a half after independence in 1964, the Malawian Government sought to transform its economy from one dependent on small-scale farms to one based on estate agriculture. The resulting demand for wage labor induced more than 300,000 Malawians to return home between the mid-1960s and the mid-1970s. In recent times, internal migration has generally been local, motivated more by marriage than economic reasons.

Mali’s total population is expected to double by 2035; its capital Bamako is one of the fastest-growing cities in Africa. A young age structure, a declining mortality rate, and a sustained high total fertility rate of 6 children per woman – the third highest in the world – ensure continued rapid population growth for the foreseeable future. Significant outmigration only marginally tempers this growth. Despite decreases, Mali’s infant, child, and maternal mortality rates remain among the highest in sub-Saharan Africa because of limited access to and adoption of family planning, early childbearing, short birth intervals, the prevalence of female genital cutting, infrequent use of skilled birth attendants, and a lack of emergency obstetrical and neonatal care.

Mali’s high total fertility rate has been virtually unchanged for decades, as a result of the ongoing preference for large families, early childbearing, the lack of female education and empowerment, poverty, and extremely low contraceptive use. Slowing Mali’s population growth by lowering its birth rate will be essential for poverty reduction, improving food security, and developing human capital and the economy.

Mali has a long history of seasonal migration and emigration driven by poverty, conflict, demographic pressure, unemployment, food insecurity, and droughts. Many Malians from rural areas migrate during the dry period to nearby villages and towns to do odd jobs or to adjoining countries to work in agriculture or mining. Pastoralists and nomads move seasonally to southern Mali or nearby coastal states. Others migrate long term to Mali’s urban areas, Cote d’Ivoire, other neighboring countries, and in smaller numbers to France, Mali’s former colonial ruler. Since the early 1990s, Mali’s role has grown as a transit country for regional migration flows and illegal migration to Europe. Human smugglers and traffickers exploit the same regional routes used for moving contraband drugs, arms, and cigarettes.

Between early 2012 and 2013, renewed fighting in northern Mali between government forces and Tuareg secessionists and their Islamist allies, a French-led international military intervention, as well as chronic food shortages, caused the displacement of hundreds of thousands of Malians. Most of those displaced domestically sought shelter in urban areas of southern Mali, except for pastoralist and nomadic groups, who abandoned their traditional routes, gave away or sold their livestock, and dispersed into the deserts of northern Mali or crossed into neighboring countries. Almost all Malians who took refuge abroad (mostly Tuareg and Maure pastoralists) stayed in the region, largely in Mauritania, Niger, and Burkina Faso.

With a sustained total fertility rate of about 4 children per woman and almost 60% of the population under the age of 25, Mauritania's population is likely to continue growing for the foreseeable future. Mauritania's large youth cohort is vital to its development prospects, but available schooling does not adequately prepare students for the workplace. Girls continue to be underrepresented in the classroom, educational quality remains poor, and the dropout rate is high. The literacy rate is only about 50%, even though access to primary education has improved since the mid-2000s. Women's restricted access to education and discriminatory laws maintain gender inequality - worsened by early and forced marriages and female genital cutting.

The denial of education to black Moors also helps to perpetuate slavery. Although Mauritania abolished slavery in 1981 (the last country in the world to do so) and made it a criminal offense in 2007, the millenniums-old practice persists largely because anti-slavery laws are rarely enforced and the custom is so ingrained.  According to a 2018 nongovernmental organization's report, a little more than 2% of Mauritania's population is enslaved, which includes individuals sujbected to forced labor and forced marriage, although many thousands of individuals who are legally free contend with discrimination, poor education, and a lack of identity papers and, therefore, live in de facto slavery.  The UN and international press outlets have claimed that up to 20% of Mauritania's population is enslaved, which would be the highest rate worldwide.

Drought, poverty, and unemployment have driven outmigration from Mauritania since the 1970s. Early flows were directed toward other West African countries, including Senegal, Mali, Cote d'Ivoire, and Gambia. The 1989 Mauritania-Senegal conflict forced thousands of black Mauritanians to take refuge in Senegal and pushed labor migrants toward the Gulf, Libya, and Europe in the late 1980s and early 1990s. Mauritania has accepted migrants from neighboring countries to fill labor shortages since its independence in 1960 and more recently has received refugees escaping civil wars, including tens of thousands of Tuaregs who fled Mali in 2012.

Mauritania was an important transit point for sub-Saharan migrants moving illegally to North Africa and Europe. In the mid-2000s, as border patrols increased in the Strait of Gibraltar, security increased around Spain's North African enclaves (Ceuta and Melilla), and Moroccan border controls intensified, illegal migration flows shifted from the Western Mediterranean to Spain's Canary Islands. In 2006, departure points moved southward along the West African coast from Morocco and Western Sahara to Mauritania's two key ports (Nouadhibou and the capital Nouakchott), and illegal migration to the Canaries peaked at almost 32,000. The numbers fell dramatically in the following years because of joint patrolling off the West African coast by Frontex (the EU's border protection agency), Spain, Mauritania, and Senegal; the expansion of Spain's border surveillance system; and the 2008 European economic downturn.

Mauritius has transitioned from a country of high fertility and high mortality rates in the 1950s and mid-1960s to one with among the lowest population growth rates in the developing world today. After World War II, Mauritius’ population began to expand quickly due to increased fertility and a dramatic drop in mortality rates as a result of improved health care and the eradication of malaria. This period of heightened population growth – reaching about 3% a year – was followed by one of the world’s most rapid birth rate declines.

The total fertility rate fell from 6.2 children per women in 1963 to 3.2 in 1972 – largely the result of improved educational attainment, especially among young women, accompanied by later marriage and the adoption of family planning methods. The family planning programs’ success was due to support from the government and eventually the traditionally pronatalist religious communities, which both recognized that controlling population growth was necessary because of Mauritius’ small size and limited resources. Mauritius’ fertility rate has consistently been below replacement level since the late 1990s, a rate that is substantially lower than nearby countries in southern Africa.

With no indigenous population, Mauritius’ ethnic mix is a product of more than two centuries of European colonialism and continued international labor migration. Sugar production relied on slave labor mainly from Madagascar, Mozambique, and East Africa from the early 18th century until its abolition in 1835, when slaves were replaced with indentured Indians. Most of the influx of indentured labor – peaking between the late 1830s and early 1860 – settled permanently creating massive population growth of more than 7% a year and reshaping the island’s social and cultural composition. While Indians represented about 12% of Mauritius’ population in 1837, they and their descendants accounted for roughly two-thirds by the end of the 19th century. Most were Hindus, but the majority of the free Indian traders were Muslims.

Mauritius again turned to overseas labor when its success in clothing and textile exports led to a labor shortage in the mid-1980s. Clothing manufacturers brought in contract workers (increasingly women) from China, India, and, to a lesser extent Bangladesh and Madagascar, who worked longer hours for lower wages under poor conditions and were viewed as more productive than locals. Downturns in the sugar and textile industries in the mid-2000s and a lack of highly qualified domestic workers for Mauritius’ growing services sector led to the emigration of low-skilled workers and a reliance on skilled foreign labor. Since 2007, Mauritius has pursued a circular migration program to enable citizens to acquire new skills and savings abroad and then return home to start businesses and to invest in the country’s development.

Morocco is undergoing a demographic transition. Its population is growing but at a declining rate, as people live longer and women have fewer children. Infant, child, and maternal mortality rates have been reduced through better health care, nutrition, hygiene, and vaccination coverage, although disparities between urban and rural and rich and poor households persist. Morocco’s shrinking child cohort reflects the decline of its total fertility rate from 5 in mid-1980s to 2.2 in 2010, which is a result of increased female educational attainment, higher contraceptive use, delayed marriage, and the desire for smaller families. Young adults (persons aged 15-29) make up almost 26% of the total population and represent a potential economic asset if they can be gainfully employed. Currently, however, many youths are unemployed because Morocco’s job creation rate has not kept pace with the growth of its working-age population. Most youths who have jobs work in the informal sector with little security or benefits.

During the second half of the 20th century, Morocco became one of the world’s top emigration countries, creating large, widely dispersed migrant communities in Western Europe. The Moroccan Government has encouraged emigration since its independence in 1956, both to secure remittances for funding national development and as an outlet to prevent unrest in rebellious (often Berber) areas. Although Moroccan labor migrants earlier targeted Algeria and France, the flood of Moroccan "guest workers" from the mid-1960s to the early 1970s spread widely across northwestern Europe to fill unskilled jobs in the booming manufacturing, mining, construction, and agriculture industries. Host societies and most Moroccan migrants expected this migration to be temporary, but deteriorating economic conditions in Morocco related to the 1973 oil crisis and tighter European immigration policies resulted in these stays becoming permanent.

A wave of family migration followed in the 1970s and 1980s, with a growing number of second generation Moroccans opting to become naturalized citizens of their host countries. Spain and Italy emerged as new destination countries in the mid-1980s, but their introduction of visa restrictions in the early 1990s pushed Moroccans increasingly to migrate either legally by marrying Moroccans already in Europe or illegally to work in the underground economy. Women began to make up a growing share of these labor migrants. At the same time, some higher-skilled Moroccans went to the US and Quebec, Canada.

In the mid-1990s, Morocco developed into a transit country for asylum seekers from sub-Saharan Africa and illegal labor migrants from sub-Saharan Africa and South Asia trying to reach Europe via southern Spain, Spain’s Canary Islands, or Spain’s North African enclaves, Ceuta and Melilla. Forcible expulsions by Moroccan and Spanish security forces have not deterred these illegal migrants or calmed Europe’s security concerns. Rabat remains unlikely to adopt an EU agreement to take back third-country nationals who have entered the EU illegally via Morocco. Thousands of other illegal migrants have chosen to stay in Morocco until they earn enough money for further travel or permanently as a "second-best" option. The launching of a regularization program in 2014 legalized the status of some migrants and granted them equal access to education, health care, and work, but xenophobia and racism remain obstacles.

Mozambique is a poor, sparsely populated country with high fertility and mortality rates and a rapidly growing youthful population – 45% of the population is younger than 15. Mozambique’s high poverty rate is sustained by natural disasters, disease, high population growth, low agricultural productivity, and the unequal distribution of wealth. The country’s birth rate is among the world’s highest, averaging around more than 5 children per woman (and higher in rural areas) for at least the last three decades. The sustained high level of fertility reflects gender inequality, low contraceptive use, early marriages and childbearing, and a lack of education, particularly among women. The high population growth rate is somewhat restrained by the country’s high HIV/AIDS and overall mortality rates. Mozambique ranks among the worst in the world for HIV/AIDS prevalence, HIV/AIDS deaths, and life expectancy at birth.

Mozambique is predominantly a country of emigration, but internal, rural-urban migration has begun to grow. Mozambicans, primarily from the country’s southern region, have been migrating to South Africa for work for more than a century. Additionally, approximately 1.7 million Mozambicans fled to Malawi, South Africa, and other neighboring countries between 1979 and 1992 to escape from civil war. Labor migrants have usually been men from rural areas whose crops have failed or who are unemployed and have headed to South Africa to work as miners; multiple generations of the same family often become miners. Since the abolition of apartheid in South Africa in 1991, other job opportunities have opened to Mozambicans, including in the informal and manufacturing sectors, but mining remains their main source of employment.

Planning officials view Namibia’s reduced population growth rate as sustainable based on the country’s economic growth over the past decade. Prior to independence in 1990, Namibia’s relatively small population grew at about 3% annually, but declining fertility and the impact of HIV/AIDS slowed this growth to 1.4% by 2011, rebounding to close to 2% by 2016. Namibia’s fertility rate has fallen over the last two decades – from about 4.5 children per woman in 1996 to 3.4 in 2016 – due to increased contraceptive use, higher educational attainment among women, and greater female participation in the labor force. The average age at first birth has stayed fairly constant, but the age at first marriage continues to increase, indicating a rising incidence of premarital childbearing.

The majority of Namibians are rural dwellers (about 55%) and live in the better-watered north and northeast parts of the country. Migration, historically male-dominated, generally flows from northern communal areas – non-agricultural lands where blacks were sequestered under the apartheid system – to agricultural, mining, and manufacturing centers in the center and south. After independence from South Africa, restrictions on internal movement eased, and rural-urban migration increased, bolstering urban growth.

Some Namibians – usually persons who are better-educated, more affluent, and from urban areas – continue to legally migrate to South Africa temporarily to visit family and friends and, much less frequently, to pursue tertiary education or better economic opportunities. Namibians concentrated along the country’s other borders make unauthorized visits to Angola, Zambia, Zimbabwe, or Botswana, to visit family and to trade agricultural goods. Few Namibians express interest in permanently settling in other countries; they prefer the safety of their homeland, have a strong national identity, and enjoy a well-supplied retail sector. Although Namibia is receptive to foreign investment and cross-border trade, intolerance toward non-citizens is widespread.

Despite being one of the poorest countries in Latin America, Nicaragua has improved its access to potable water and sanitation and has ameliorated its life expectancy, infant and child mortality, and immunization rates. However, income distribution is very uneven, and the poor, agriculturalists, and indigenous people continue to have less access to healthcare services. Nicaragua's total fertility rate has fallen from around 6 children per woman in 1980 to below replacement level today, but the high birth rate among adolescents perpetuates a cycle of poverty and low educational attainment.

Nicaraguans emigrate primarily to Costa Rica and to a lesser extent the United States. Nicaraguan men have been migrating seasonally to Costa Rica to harvest bananas and coffee since the early 20th century. Political turmoil, civil war, and natural disasters from the 1970s through the 1990s dramatically increased the flow of refugees and permanent migrants seeking jobs, higher wages, and better social and healthcare benefits. Since 2000, Nicaraguan emigration to Costa Rica has slowed and stabilized. Today roughly 300,000 Nicaraguans are permanent residents of Costa Rica - about 75% of the foreign population - and thousands more migrate seasonally for work, many illegally.

Niger has the highest total fertility rate (TFR) of any country in the world, averaging close to 7 children per woman in 2016. A slight decline in fertility over the last few decades has stalled. This leveling off of the high fertility rate is in large part a product of the continued desire for large families. In Niger, the TFR is lower than the desired fertility rate, which makes it unlikely that contraceptive use will increase. The high TFR sustains rapid population growth and a large youth population – almost 70% of the populace is under the age of 25. Gender inequality, including a lack of educational opportunities for women and early marriage and childbirth, also contributes to high population growth.

Because of large family sizes, children are inheriting smaller and smaller parcels of land. The dependence of most Nigeriens on subsistence farming on increasingly small landholdings, coupled with declining rainfall and the resultant shrinkage of arable land, are all preventing food production from keeping up with population growth.

For more than half a century, Niger's lack of economic development has led to steady net outmigration. In the 1960s, Nigeriens mainly migrated to coastal West African countries to work on a seasonal basis. Some headed to Libya and Algeria in the 1970s to work in the booming oil industry until its decline in the 1980s. Since the 1990s, the principal destinations for Nigerien labor migrants have been West African countries, especially Burkina Faso and Cote d’Ivoire, while emigration to Europe and North America has remained modest. During the same period, Niger’s desert trade route town Agadez became a hub for West African and other sub-Saharan migrants crossing the Sahara to North Africa and sometimes onward to Europe.

More than 60,000 Malian refugees have fled to Niger since violence between Malian government troops and armed rebels began in early 2012. Ongoing attacks by the Boko Haram Islamist insurgency, dating to 2013 in northern Nigeria and February 2015 in southeastern Niger, have pushed tens of thousands of Nigerian refugees and Nigerien returnees across the border to Niger and to displace thousands of locals in Niger’s already impoverished Diffa region.

Nigeria’s population is projected to grow from more than 186 million people in 2016 to 392 million in 2050, becoming the world’s fourth most populous country. Nigeria’s sustained high population growth rate will continue for the foreseeable future because of population momentum and its high birth rate. Abuja has not successfully implemented family planning programs to reduce and space births because of a lack of political will, government financing, and the availability and affordability of services and products, as well as a cultural preference for large families. Increased educational attainment, especially among women, and improvements in health care are needed to encourage and to better enable parents to opt for smaller families.

Nigeria needs to harness the potential of its burgeoning youth population in order to boost economic development, reduce widespread poverty, and channel large numbers of unemployed youth into productive activities and away from ongoing religious and ethnic violence. While most movement of Nigerians is internal, significant emigration regionally and to the West provides an outlet for Nigerians looking for economic opportunities, seeking asylum, and increasingly pursuing higher education. Immigration largely of West Africans continues to be insufficient to offset emigration and the loss of highly skilled workers. Nigeria also is a major source, transit, and destination country for forced labor and sex trafficking.

Panama is a country of demographic and economic contrasts. It is in the midst of a demographic transition, characterized by steadily declining rates of fertility, mortality, and population growth, but disparities persist based on wealth, geography, and ethnicity. Panama has one of the fastest growing economies in Latin America and dedicates substantial funding to social programs, yet poverty and inequality remain prevalent. The indigenous population accounts for a growing share of Panama's poor and extreme poor, while the non-indigenous rural poor have been more successful at rising out of poverty through rural-to-urban labor migration. The government's large expenditures on untargeted, indirect subsidies for water, electricity, and fuel have been ineffective, but its conditional cash transfer program has shown some promise in helping to decrease extreme poverty among the indigenous population.

Panama has expanded access to education and clean water, but the availability of sanitation and, to a lesser extent, electricity remains poor. The increase in secondary schooling - led by female enrollment - is spreading to rural and indigenous areas, which probably will help to alleviate poverty if educational quality and the availability of skilled jobs improve. Inadequate access to sanitation contributes to a high incidence of diarrhea in Panama's children, which is one of the main causes of Panama's elevated chronic malnutrition rate, especially among indigenous communities.

Paraguay falls below the Latin American average in several socioeconomic categories, including immunization rates, potable water, sanitation, and secondary school enrollment, and has greater rates of income inequality and child and maternal mortality. Paraguay's poverty rate has declined in recent years but remains high, especially in rural areas, with more than a third of the population below the poverty line. However, the well-being of the poor in many regions has improved in terms of housing quality and access to clean water, telephone service, and electricity. The fertility rate continues to drop, declining sharply from an average 4.3 births per woman in the late 1990s to about 2 in 2013, as a result of the greater educational attainment of women, increased use of contraception, and a desire for smaller families among young women.

Paraguay is a country of emigration; it has not attracted large numbers of immigrants because of political instability, civil wars, years of dictatorship, and the greater appeal of neighboring countries. Paraguay first tried to encourage immigration in 1870 in order to rebound from the heavy death toll it suffered during the War of the Triple Alliance, but it received few European and Middle Eastern immigrants. In the 20th century, limited numbers of immigrants arrived from Lebanon, Japan, South Korea, and China, as well as Mennonites from Canada, Russia, and Mexico. Large flows of Brazilian immigrants have been arriving since the 1960s, mainly to work in agriculture. Paraguayans continue to emigrate to Argentina, Brazil, Uruguay, the United States, Italy, Spain, and France.

Peru's urban and coastal communities have benefited much more from recent economic growth than rural, Afro-Peruvian, indigenous, and poor populations of the Amazon and mountain regions. The poverty rate has dropped substantially during the last decade but remains stubbornly high at about 30% (more than 55% in rural areas). After remaining almost static for about a decade, Peru's malnutrition rate began falling in 2005, when the government introduced a coordinated strategy focusing on hygiene, sanitation, and clean water. School enrollment has improved, but achievement scores reflect ongoing problems with educational quality. Many poor children temporarily or permanently drop out of school to help support their families. About a quarter to a third of Peruvian children aged 6 to 14 work, often putting in long hours at hazardous mining or construction sites.

Peru was a country of immigration in the 19th and early 20th centuries, but has become a country of emigration in the last few decades. Beginning in the 19th century, Peru brought in Asian contract laborers mainly to work on coastal plantations. Populations of Chinese and Japanese descent - among the largest in Latin America - are economically and culturally influential in Peru today. Peruvian emigration began rising in the 1980s due to an economic crisis and a violent internal conflict, but outflows have stabilized in the last few years as economic conditions have improved. Nonetheless, more than 2 million Peruvians have emigrated in the last decade, principally to the US, Spain, and Argentina.

Rwanda’s fertility rate declined sharply during the last decade, as a result of the government’s commitment to family planning, the increased use of contraceptives, and a downward trend in ideal family size. Increases in educational attainment, particularly among girls, and exposure to social media also contributed to the reduction in the birth rate. The average number of births per woman decreased from a 5.6 in 2005 to 4.5 in 2016. Despite these significant strides in reducing fertility, Rwanda’s birth rate remains very high and will continue to for an extended period of time because of its large population entering reproductive age. Because Rwanda is one of the most densely populated countries in Africa, its persistent high population growth and increasingly small agricultural landholdings will put additional strain on families’ ability to raise foodstuffs and access potable water. These conditions will also hinder the government’s efforts to reduce poverty and prevent environmental degradation.

The UNHCR recommended that effective 30 June 2013 countries invoke a cessation of refugee status for those Rwandans who fled their homeland between 1959 and 1998, including the 1994 genocide, on the grounds that the conditions that drove them to seek protection abroad no longer exist. The UNHCR’s decision is controversial because many Rwandan refugees still fear persecution if they return home, concerns that are supported by the number of Rwandans granted asylum since 1998 and by the number exempted from the cessation. Rwandan refugees can still seek an exemption or local integration, but host countries are anxious to send the refugees back to Rwanda and are likely to avoid options that enable them to stay. Conversely, Rwanda itself hosts almost 160,000 refugees as of 2017; virtually all of them fleeing conflict in neighboring Burundi and the Democratic Republic of the Congo.

The vast majority of the population of Saint Helena, Ascension, and Tristan da Cunha live on Saint Helena. Ascension has no indigenous or permanent residents and is inhabited only by persons contracted to work on the island (mainly with the UK and US military or in the space and communications industries) or their dependents, while Tristan da Cunha – the main island in a small archipelago – has fewer than 300 residents. The population of Saint Helena consists of the descendants of 17th century British sailors and settlers from the East India Company, African slaves, and indentured servants and laborers from India, Indonesia, and China. Most of the population of Ascension are Saint Helenians, Britons, and Americans, while that of Tristan da Cunha descends from shipwrecked sailors and Saint Helenians.

Change in Saint Helena’s population size is driven by net outward migration. Since the 1980s, Saint Helena’s population steadily has shrunk and aged as the birth rate has decreased and many working-age residents left for better opportunities elsewhere. The restoration of British citizenship in 2002 accelerated family emigration; from 1998 to 2008 alone, population declined by about 20%.

In the last few years, population has experienced some temporary growth, as foreigners and returning Saint Helenians, have come to build an international airport, but numbers are beginning to fade as the project reaches completion and workers depart. In the long term, once the airport is fully operational, increased access to the remote island has the potential to boost tourism and fishing, provide more jobs for Saint Helenians domestically, and could encourage some ex-patriots to return home. In the meantime, however, Saint Helena, Ascension, and Tristan da Cunha have to contend with the needs of an aging population. The elderly population of the islands has risen from an estimated 9.4% in 1998 to 20.4% in 2016.

Sao Tome and Principe’s youthful age structure – more than 60% of the population is under the age of 25 – and high fertility rate ensure future population growth. Although Sao Tome has a net negative international migration rate, emigration is not a sufficient safety valve to reduce already high levels of unemployment and poverty. While literacy and primary school attendance have improved in recent years, Sao Tome still struggles to improve its educational quality and to increase its secondary school completion rate. Despite some improvements in education and access to healthcare, Sao Tome and Principe has much to do to decrease its high poverty rate, create jobs, and increase its economic growth.

The population of Sao Tome and Principe descends primarily from the islands’ colonial Portuguese settlers, who first arrived in the late 15th century, and the much larger number of African slaves brought in for sugar production and the slave trade. For about 100 years after the abolition of slavery in 1876, the population was further shaped by the widespread use of imported unskilled contract laborers from Portugal’s other African colonies, who worked on coffee and cocoa plantations. In the first decades after abolition, most workers were brought from Angola under a system similar to slavery. While Angolan laborers were technically free, they were forced or coerced into long contracts that were automatically renewed and extended to their children. Other contract workers from Mozambique and famine-stricken Cape Verde first arrived in the early 20th century under short-term contracts and had the option of repatriation, although some chose to remain in Sao Tome and Principe.

Today’s Sao Tomean population consists of mesticos (creole descendants of the European immigrants and African slaves that first inhabited the islands), forros (descendants of freed African slaves), angolares (descendants of runaway African slaves that formed a community in the south of Sao Tome Island and today are fishermen), servicais (contract laborers from Angola, Mozambique, and Cape Verde), tongas (locally born children of contract laborers), and lesser numbers of Europeans and Asians.

Senegal has a large and growing youth population but has not been successful in developing its potential human capital. Senegal’s high total fertility rate of almost 4.5 children per woman continues to bolster the country’s large youth cohort – more than 60% of the population is under the age of 25. Fertility remains high because of the continued desire for large families, the low use of family planning, and early childbearing. Because of the country’s high illiteracy rate (more than 40%), high unemployment (even among university graduates), and widespread poverty, Senegalese youths face dim prospects; women are especially disadvantaged.

Senegal historically was a destination country for economic migrants, but in recent years West African migrants more often use Senegal as a transit point to North Africa – and sometimes illegally onward to Europe. The country also has been host to several thousand black Mauritanian refugees since they were expelled from their homeland during its 1989 border conflict with Senegal. The country’s economic crisis in the 1970s stimulated emigration; departures accelerated in the 1990s. Destinations shifted from neighboring countries, which were experiencing economic decline, civil wars, and increasing xenophobia, to Libya and Mauritania because of their booming oil industries and to developed countries (most notably former colonial ruler France, as well as Italy and Spain). The latter became attractive in the 1990s because of job opportunities and their periodic regularization programs (legalizing the status of illegal migrants).

Additionally, about 16,000 Senegalese refugees still remain in The Gambia and Guinea-Bissau as a result of more than 30 years of fighting between government forces and rebel separatists in southern Senegal’s Casamance region.

Seychelles has no indigenous population and was first permanently settled by a small group of French planters, African slaves, and South Indians in 1770. Seychelles’ modern population is composed of the descendants of French and later British settlers, Africans, and Indian, Chinese, and Middle Eastern traders and is concentrated on three of its 155 islands – the vast majority on Mahe and lesser numbers on Praslin and La Digue. Seychelles’ population grew rapidly during the second half of the 20th century, largely due to natural increase, but the pace has slowed because of fertility decline. The total fertility rate dropped sharply from 4.0 children per woman in 1980 to 1.9 in 2015, mainly as a result of a family planning program, free education and health care, and increased female labor force participation. Life expectancy has increased steadily, but women on average live 9 years longer than men, a difference that is higher than that typical of developed countries.

The combination of reduced fertility and increased longevity has resulted in an aging population, which will put pressure on the government’s provision of pensions and health care. Seychelles’ sustained investment in social welfare services, such as free primary health care and education up to the post-secondary level, have enabled the country to achieve a high human development index score – among the highest in Africa. Despite some of its health and education indicators being nearly on par with Western countries, Seychelles has a high level of income inequality.

An increasing number of migrant workers – mainly young men – have been coming to Seychelles in recent years to work in the construction and tourism industries. As of 2011, foreign workers made up nearly a quarter of the workforce. Indians are the largest non-Seychellois population – representing half of the country’s foreigners – followed by Malagasy.

Sierra Leone’s youthful and growing population is driven by its high total fertility rate (TFR) of almost 5 children per woman, which has declined little over the last two decades. Its elevated TFR is sustained by the continued desire for large families, the low level of contraceptive use, and the early start of childbearing. Despite its high TFR, Sierra Leone’s population growth is somewhat tempered by high infant, child, and maternal mortality rates that are among the world’s highest and are a result of poverty, a lack of potable water and sanitation, poor nutrition, limited access to quality health care services, and the prevalence of female genital cutting.

Sierra Leone’s large youth cohort – about 60% of the population is under the age of 25 – continues to struggle with high levels of unemployment, which was one of the major causes of the country’s 1991-2002 civil war and remains a threat to stability today. Its estimated 60% youth unemployment rate is attributed to high levels of illiteracy and unskilled labor, a lack of private sector jobs, and low pay.

Sierra Leone has been a source of and destination for refugees. Sierra Leone’s civil war internally displaced as many as 2 million people, or almost half the population, and forced almost another half million to seek refuge in neighboring countries (370,000 Sierra Leoneans fled to Guinea and 120,000 to Liberia). The UNHCR has helped almost 180,000 Sierra Leoneans to return home, while more than 90,000 others have repatriated on their own. Of the more than 65,000 Liberians who took refuge in Sierra Leone during their country’s civil war (1989-2003), about 50,000 have been voluntarily repatriated by the UNHCR and others have returned home independently. As of 2015, less than 1,000 Liberians still reside in Sierra Leone.

Somalia scores very low for most humanitarian indicators, suffering from poor governance, protracted internal conflict, underdevelopment, economic decline, poverty, social and gender inequality, and environmental degradation. Despite civil war and famine raising its mortality rate, Somalia’s high fertility rate and large proportion of people of reproductive age maintain rapid population growth, with each generation being larger than the prior one. More than 60% of Somalia’s population is younger than 25, and the fertility rate is among the world’s highest at almost 6 children per woman – a rate that has decreased little since the 1970s.

A lack of educational and job opportunities is a major source of tension for Somalia’s large youth cohort, making them vulnerable to recruitment by extremist and pirate groups. Somalia has one of the world’s lowest primary school enrollment rates – just over 40% of children are in school – and one of world’s highest youth unemployment rates. Life expectancy is low as a result of high infant and maternal mortality rates, the spread of preventable diseases, poor sanitation, chronic malnutrition, and inadequate health services.

During the two decades of conflict that followed the fall of the SIAD regime in 1991, hundreds of thousands of Somalis fled their homes. Today Somalia is the world’s third highest source country for refugees, after Syria and Afghanistan. Insecurity, drought, floods, food shortages, and a lack of economic opportunities are the driving factors.

As of 2016, more than 1.1 million Somali refugees were hosted in the region, mainly in Kenya, Yemen, Egypt, Ethiopia, Djibouti, and Uganda, while more than 1.1 million Somalis were internally displaced. Since the implementation of a tripartite voluntary repatriation agreement among Kenya, Somalia, and the UNHCR in 2013, nearly 40,000 Somali refugees have returned home from Kenya’s Dadaab refugee camp – still houses to approximately 260,000 Somalis. The flow sped up rapidly after the Kenyan Government in May 2016 announced its intention to close the camp, worsening security and humanitarian conditions in receiving communities in south-central Somalia. Despite the conflict in Yemen, thousands of Somalis and other refugees and asylum seekers from the Horn of Africa risk their lives crossing the Gulf of Aden to reach Yemen and beyond (often Saudi Arabia). Bossaso in Puntland overtook Obock, Djibouti, as the primary departure point in mid-2014.

South Africa’s youthful population is gradually aging, as the country’s total fertility rate (TFR) has declined dramatically from about 6 children per woman in the 1960s to roughly 2.2 in 2014. This pattern is similar to fertility trends in South Asia, the Middle East, and North Africa, and sets South Africa apart from the rest of sub-Saharan Africa, where the average TFR remains higher than other regions of the world. Today, South Africa’s decreasing number of reproductive age women is having fewer children, as women increase their educational attainment, workforce participation, and use of family planning methods; delay marriage; and opt for smaller families.

As the proportion of working-age South Africans has grown relative to children and the elderly, South Africa has been unable to achieve a demographic dividend because persistent high unemployment and the prevalence of HIV/AIDs have created a larger-than-normal dependent population. HIV/AIDS was also responsible for South Africa’s average life expectancy plunging to less than 43 years in 2008; it has rebounded to 63 years as of 2017. HIV/AIDS continues to be a serious public health threat, although awareness-raising campaigns and the wider availability of anti-retroviral drugs is stabilizing the number of new cases, enabling infected individuals to live longer, healthier lives, and reducing mother-child transmissions.

Migration to South Africa began in the second half of the 17th century when traders from the Dutch East India Company settled in the Cape and started using slaves from South and southeast Asia (mainly from India but also from present-day Indonesia, Bangladesh, Sri Lanka, and Malaysia) and southeast Africa (Madagascar and Mozambique) as farm laborers and, to a lesser extent, as domestic servants. The Indian subcontinent remained the Cape Colony’s main source of slaves in the early 18th century, while slaves were increasingly obtained from southeast Africa in the latter part of the 18th century and into the 19th century under British rule.

After slavery was completely abolished in the British Empire in 1838, South Africa’s colonists turned to temporary African migrants and indentured labor through agreements with India and later China, countries that were anxious to export workers to alleviate domestic poverty and overpopulation. Of the more than 150,000 indentured Indian laborers hired to work in Natal’s sugar plantations between 1860 and 1911, most exercised the right as British subjects to remain permanently (a small number of Indian immigrants came freely as merchants). Because of growing resentment toward Indian workers, the 63,000 indentured Chinese workers who mined gold in Transvaal between 1904 and 1911 were under more restrictive contracts and generally were forced to return to their homeland.

In the late 19th century and nearly the entire 20th century, South Africa’s then British colonies’ and Dutch states’ enforced selective immigration policies that welcomed "assimilable" white Europeans as permanent residents but excluded or restricted other immigrants. Following the Union of South Africa’s passage of a law in 1913 prohibiting Asian and other non-white immigrants and its elimination of the indenture system in 1917, temporary African contract laborers from neighboring countries became the dominant source of labor in the burgeoning mining industries. Others worked in agriculture and smaller numbers in manufacturing, domestic service, transportation, and construction. Throughout the 20th century, at least 40% of South Africa’s miners were foreigners; the numbers peaked at over 80% in the late 1960s. Mozambique, Lesotho, Botswana, and Eswatini were the primary sources of miners, and Malawi and Zimbabwe were periodic suppliers.

Under apartheid, a "two gates" migration policy focused on policing and deporting illegal migrants rather than on managing migration to meet South Africa’s development needs. The exclusionary 1991 Aliens Control Act limited labor recruitment to the highly skilled as defined by the ruling white minority, while bilateral labor agreements provided exemptions that enabled the influential mining industry and, to a lesser extent, commercial farms, to hire temporary, low-paid workers from neighboring states. Illegal African migrants were often tacitly allowed to work for low pay in other sectors but were always under threat of deportation.

The abolishment of apartheid in 1994 led to the development of a new inclusive national identity and the strengthening of the country’s restrictive immigration policy. Despite South Africa’s protectionist approach to immigration, the downsizing and closing of mines, and rising unemployment, migrants from across the continent believed that the country held work opportunities. Fewer African labor migrants were issued temporary work permits and, instead, increasingly entered South Africa with visitors’ permits or came illegally, which drove growth in cross-border trade and the informal job market. A new wave of Asian immigrants has also arrived over the last two decades, many operating small retail businesses.

In the post-apartheid period, increasing numbers of highly skilled white workers emigrated, citing dissatisfaction with the political situation, crime, poor services, and a reduced quality of life. The 2002 Immigration Act and later amendments were intended to facilitate the temporary migration of skilled foreign labor to fill labor shortages, but instead the legislation continues to create regulatory obstacles. Although the education system has improved and brain drain has slowed in the wake of the 2008 global financial crisis, South Africa continues to face skills shortages in several key sectors, such as health care and technology.

South Africa’s stability and economic growth has acted as a magnet for refugees and asylum seekers from nearby countries, despite the prevalence of discrimination and xenophobic violence. Refugees have included an estimated 350,000 Mozambicans during its 1980s civil war and, more recently, several thousand Somalis, Congolese, and Ethiopians. Nearly all of the tens of thousands of Zimbabweans who have applied for asylum in South Africa have been categorized as economic migrants and denied refuge.

South Sudan, independent from Sudan since July 2011 after decades of civil war, is one of the world’s poorest countries and ranks among the lowest in many socioeconomic categories. Problems are exacerbated by ongoing tensions with Sudan over oil revenues and land borders, fighting between government forces and rebel groups, and inter-communal violence. Most of the population lives off of farming, while smaller numbers rely on animal husbandry; more than 80% of the populace lives in rural areas. The maternal mortality rate is among the world’s highest for a variety of reasons, including a shortage of health care workers, facilities, and supplies; poor roads and a lack of transport; and cultural beliefs that prevent women from seeking obstetric care. Most women marry and start having children early, giving birth at home with the assistance of traditional birth attendants, who are unable to handle complications.

Educational attainment is extremely poor due to the lack of schools, qualified teachers, and materials. Less than a third of the population is literate (the rate is even lower among women), and half live below the poverty line. Teachers and students are also struggling with the switch from Arabic to English as the language of instruction. Many adults missed out on schooling because of warfare and displacement.

Almost 2 million South Sudanese have sought refuge in neighboring countries since the current conflict began in December 2013. Another 1.96 million South Sudanese are internally displaced as of August 2017. Despite South Sudan’s instability and lack of infrastructure and social services, more than 240,000 people have fled to South Sudan to escape fighting in Sudan.

Suriname is a pluralistic society consisting primarily of Creoles (persons of mixed African and European heritage), the descendants of escaped African slaves known as Maroons, and the descendants of Indian and Javanese (Indonesian) contract workers. The country overall is in full, post-industrial demographic transition, with a low fertility rate, a moderate mortality rate, and a rising life expectancy. However, the Maroon population of the rural interior lags behind because of lower educational attainment and contraceptive use, higher malnutrition, and significantly less access to electricity, potable water, sanitation, infrastructure, and health care.

Some 350,000 people of Surinamese descent live in the Netherlands, Suriname's former colonial ruler. In the 19th century, better-educated, largely Dutch-speaking Surinamese began emigrating to the Netherlands. World War II interrupted the outflow, but it resumed after the war when Dutch labor demands grew - emigrants included all segments of the Creole population. Suriname still is strongly influenced by the Netherlands because most Surinamese have relatives living there and it is the largest supplier of development aid. Other emigration destinations include French Guiana and the United States. Suriname's immigration rules are flexible, and the country is easy to enter illegally because rainforests obscure its borders. Since the mid-1980s, Brazilians have settled in Suriname's capital, Paramaribo, or eastern Suriname, where they mine gold. This immigration is likely to slowly re-orient Suriname toward its Latin American roots.

Tanzania has the largest population in East Africa and the lowest population density; almost a third of the population is urban. Tanzania’s youthful population – about two-thirds of the population is under 25 – is growing rapidly because of the high total fertility rate of 4.8 children per woman. Progress in reducing the birth rate has stalled, sustaining the country’s nearly 3% annual growth. The maternal mortality rate has improved since 2000, yet it remains very high because of early and frequent pregnancies, inadequate maternal health services, and a lack of skilled birth attendants – problems that are worse among poor and rural women. Tanzania has made strides in reducing under-5 and infant mortality rates, but a recent drop in immunization threatens to undermine gains in child health. Malaria is a leading killer of children under 5, while HIV is the main source of adult mortality

For Tanzania, most migration is internal, rural to urban movement, while some temporary labor migration from towns to plantations takes place seasonally for harvests. Tanzania was Africa’s largest refugee-hosting country for decades, hosting hundreds of thousands of refugees from the Great Lakes region, primarily Burundi, over the last fifty years. However, the assisted repatriation and naturalization of tens of thousands of Burundian refugees between 2002 and 2014 dramatically reduced the refugee population. Tanzania is increasingly a transit country for illegal migrants from the Horn of Africa and the Great Lakes region who are heading to southern Africa for security reasons and/or economic opportunities. Some of these migrants choose to settle in Tanzania.

Togo’s population is estimated to have grown to four times its size between 1960 and 2010. With nearly 60% of its populace under the age of 25 and a high annual growth rate attributed largely to high fertility, Togo’s population is likely to continue to expand for the foreseeable future. Reducing fertility, boosting job creation, and improving education will be essential to reducing the country’s high poverty rate. In 2008, Togo eliminated primary school enrollment fees, leading to higher enrollment but increased pressure on limited classroom space, teachers, and materials. Togo has a good chance of achieving universal primary education, but educational quality, the underrepresentation of girls, and the low rate of enrollment in secondary and tertiary schools remain concerns.

Togo is both a country of emigration and asylum. In the early 1990s, southern Togo suffered from the economic decline of the phosphate sector and ethnic and political repression at the hands of dictator Gnassingbe EYADEMA and his northern, Kabye-dominated administration. The turmoil led 300,000 to 350,000 predominantly southern Togolese to flee to Benin and Ghana, with most not returning home until relative stability was restored in 1997. In 2005, another outflow of 40,000 Togolese to Benin and Ghana occurred when violence broke out between the opposition and security forces over the disputed election of EYADEMA’s son Faure GNASSINGBE to the presidency. About half of the refugees reluctantly returned home in 2006, many still fearing for their safety. Despite ethnic tensions and periods of political unrest, Togo in September 2017 was home to more than 9,600 refugees from Ghana.

The Tunisian Government took steps in the 1960s to decrease population growth and gender inequality in order to improve socioeconomic development. Through its introduction of a national family planning program (the first in Africa) and by raising the legal age of marriage, Tunisia rapidly reduced its total fertility rate from about 7 children per woman in 1960 to 2 today. Unlike many of its North African and Middle Eastern neighbors, Tunisia will soon be shifting from being a youth-bulge country to having a transitional age structure, characterized by lower fertility and mortality rates, a slower population growth rate, a rising median age, and a longer average life expectancy.

Currently, the sizable young working-age population is straining Tunisia’s labor market and education and health care systems. Persistent high unemployment among Tunisia’s growing workforce, particularly its increasing number of university graduates and women, was a key factor in the uprisings that led to the overthrow of the BEN ALI regime in 2011. In the near term, Tunisia’s large number of jobless young, working-age adults; deficiencies in primary and secondary education; and the ongoing lack of job creation and skills mismatches could contribute to future unrest. In the longer term, a sustained low fertility rate will shrink future youth cohorts and alleviate demographic pressure on Tunisia’s labor market, but employment and education hurdles will still need to be addressed.

Tunisia has a history of labor emigration. In the 1960s, workers migrated to European countries to escape poor economic conditions and to fill Europe’s need for low-skilled labor in construction and manufacturing. The Tunisian Government signed bilateral labor agreements with France, Germany, Belgium, Hungary, and the Netherlands, with the expectation that Tunisian workers would eventually return home. At the same time, growing numbers of Tunisians headed to Libya, often illegally, to work in the expanding oil industry. In the mid-1970s, with European countries beginning to restrict immigration and Tunisian-Libyan tensions brewing, Tunisian economic migrants turned toward the Gulf countries. After mass expulsions from Libya in 1983, Tunisian migrants increasingly sought family reunification in Europe or moved illegally to southern Europe, while Tunisia itself developed into a transit point for sub-Saharan migrants heading to Europe.

Following the ousting of BEN ALI in 2011, the illegal migration of unemployed Tunisian youths to Italy and onward to France soared into the tens of thousands. Thousands more Tunisian and foreign workers escaping civil war in Libya flooded into Tunisia and joined the exodus. A readmission agreement signed by Italy and Tunisia in April 2011 helped stem the outflow, leaving Tunisia and international organizations to repatriate, resettle, or accommodate some 1 million Libyans and third-country nationals.

Uganda has one of the youngest and most rapidly growing populations in the world; its total fertility rate is among the world’s highest at 5.8 children per woman. Except in urban areas, actual fertility exceeds women’s desired fertility by one or two children, which is indicative of the widespread unmet need for contraception, lack of government support for family planning, and a cultural preference for large families. High numbers of births, short birth intervals, and the early age of childbearing contribute to Uganda’s high maternal mortality rate. Gender inequities also make fertility reduction difficult; women on average are less-educated, participate less in paid employment, and often have little say in decisions over childbearing and their own reproductive health. However, even if the birth rate were significantly reduced, Uganda’s large pool of women entering reproductive age ensures rapid population growth for decades to come.

Unchecked, population increase will further strain the availability of arable land and natural resources and overwhelm the country’s limited means for providing food, employment, education, health care, housing, and basic services. The country’s north and northeast lag even further behind developmentally than the rest of the country as a result of long-term conflict (the Ugandan Bush War 1981-1986 and more than 20 years of fighting between the Lord’s Resistance Army (LRA) and Ugandan Government forces), ongoing inter-communal violence, and periodic natural disasters.

Uganda has been both a source of refugees and migrants and a host country for refugees. In 1972, then President Idi AMIN, in his drive to return Uganda to Ugandans, expelled the South Asian population that composed a large share of the country’s business people and bankers. Since the 1970s, thousands of Ugandans have emigrated, mainly to southern Africa or the West, for security reasons, to escape poverty, to search for jobs, and for access to natural resources. The emigration of Ugandan doctors and nurses due to low wages is a particular concern given the country’s shortage of skilled health care workers. Africans escaping conflicts in neighboring states have found refuge in Uganda since the 1950s; the country currently struggles to host tens of thousands from the Democratic Republic of the Congo, South Sudan, and other nearby countries.

Uruguay rates high for most development indicators and is known for its secularism, liberal social laws, and well-developed social security, health, and educational systems. It is one of the few countries in Latin America and the Caribbean where the entire population has access to clean water. Uruguay's provision of free primary through university education has contributed to the country's high levels of literacy and educational attainment. However, the emigration of human capital has diminished the state's return on its investment in education. Remittances from the roughly 18% of Uruguayans abroad amount to less than 1 percent of national GDP. The emigration of young adults and a low birth rate are causing Uruguay's population to age rapidly.

In the 1960s, Uruguayans for the first time emigrated en masse - primarily to Argentina and Brazil - because of economic decline and the onset of more than a decade of military dictatorship. Economic crises in the early 1980s and 2002 also triggered waves of emigration, but since 2002 more than 70% of Uruguayan emigrants have selected the US and Spain as destinations because of better job prospects. Uruguay had a tiny population upon its independence in 1828 and welcomed thousands of predominantly Italian and Spanish immigrants, but the country has not experienced large influxes of new arrivals since the aftermath of World War II. More recent immigrants include Peruvians and Arabs.

Social investment in Venezuela during the CHAVEZ administration reduced poverty from nearly 50% in 1999 to about 27% in 2011, increased school enrollment, substantially decreased infant and child mortality, and improved access to potable water and sanitation through social investment. "Missions" dedicated to education, nutrition, healthcare, and sanitation were funded through petroleum revenues. The sustainability of this progress remains questionable, however, as the continuation of these social programs depends on the prosperity of Venezuela's oil industry. In the long-term, education and health care spending may increase economic growth and reduce income inequality, but rising costs and the staffing of new health care jobs with foreigners are slowing development.

While CHAVEZ was in power, more than one million predominantly middle- and upper-class Venezuelans are estimated to have emigrated. The brain drain is attributed to a repressive political system, lack of economic opportunities, steep inflation, a high crime rate, and corruption. Thousands of oil engineers emigrated to Canada, Colombia, and the United States following CHAVEZ's firing of over 20,000 employees of the state-owned petroleum company during a 2002-03 oil strike. Additionally, thousands of Venezuelans of European descent have taken up residence in their ancestral homelands. Nevertheless, Venezuela has attracted hundreds of thousands of immigrants from South America and southern Europe because of its lenient migration policy and the availability of education and health care. Venezuela also has been a fairly accommodating host to Colombian refugees, numbering about 170,000 as of year-end 2016. However, since 2014, falling oil prices have driven a major economic crisis that has pushed Venezuelans from all walks of life to migrate or to seek asylum abroad to escape severe shortages of food, water, and medicine; soaring inflation; unemployment; and violence. As of November 2019, an estimated 4.6 million Venezuelans were refugees or migrants worldwide, with almost 80% taking refuge in Latin America and the Caribbean (notably Colombia, Peru, Chile, Ecuador, Argentina, and Brazil, as well as the Dominican Republic, Aruba, and Curacao). Asylum applications increased significantly in the US and Brazil in 2016 and 2017. Several receiving countries are making efforts to increase immigration restrictions and to deport illegal Venezuelan migrants - Ecuador and Peru in August 2018 began requiring valid passports for entry, which are difficult to obtain for Venezuelans. Nevertheless, Venezuelans continue to migrate to avoid economic collapse at home.

Western Sahara is a non-self governing territory; approximately 75% is under Moroccan control. It was inhabited almost entirely by Sahrawi pastoral nomads until the mid-20th century. Their traditional vast migratory ranges, based on following unpredictable rainfall, did not coincide with colonial and later international borders. Since the 1930s, most Sahrawis have been compelled to adopt a sedentary lifestyle and to live in urban settings as a result of fighting, the presence of minefields, job opportunities in the phosphate industry, prolonged drought, the closure of Western Sahara’s border with Mauritania from 1979-2002, and the construction of the defensive berm separating Moroccan- and Polisario-controlled (Sahrawi liberalization movement) areas. Morocco supported rapid urbanization to facilitate surveillance and security.

Today more than 80% of Western Sahara’s population lives in urban areas; more than 40% live in the administrative center Laayoune. Moroccan immigration has altered the composition and dramatically increased the size of Western Sahara’s population. Morocco maintains a large military presence in Western Sahara and has encouraged its citizens to settle there, offering bonuses, pay raises, and food subsidies to civil servants and a tax exemption, in order to integrate Western Sahara into the Moroccan Kingdom and, Sahrawis contend, to marginalize the native population.

Western Saharan Sahrawis have been migrating to Europe, principally to former colonial ruler Spain, since the 1950s. Many who moved to refugee camps in Tindouf, Algeria, also have migrated to Spain and Italy, usually alternating between living in cities abroad with periods back at the camps. The Polisario claims that the population of the Tindouf camps is about 155,000, but this figure may include thousands of Arabs and Tuaregs from neighboring countries. Because international organizations have been unable to conduct an independent census in Tindouf, the UNHCR bases its aid on a figure of 90,000 refugees. Western Saharan coastal towns emerged as key migration transit points (for reaching Spain’s Canary Islands) in the mid-1990s, when Spain’s and Italy’s tightening of visa restrictions and EU pressure on Morocco and other North African countries to control illegal migration pushed sub-Saharan African migrants to shift their routes to the south.

Zambia’s poor, youthful population consists primarily of Bantu-speaking people representing nearly 70 different ethnicities. Zambia’s high fertility rate continues to drive rapid population growth, averaging almost 3 percent annually between 2000 and 2010. The country’s total fertility rate has fallen by less than 1.5 children per woman during the last 30 years and still averages among the world’s highest, almost 6 children per woman, largely because of the country’s lack of access to family planning services, education for girls, and employment for women. Zambia also exhibits wide fertility disparities based on rural or urban location, education, and income. Poor, uneducated women from rural areas are more likely to marry young, to give birth early, and to have more children, viewing children as a sign of prestige and recognizing that not all of their children will live to adulthood. HIV/AIDS is prevalent in Zambia and contributes to its low life expectancy.

Zambian emigration is low compared to many other African countries and is comprised predominantly of the well-educated. The small amount of brain drain, however, has a major impact in Zambia because of its limited human capital and lack of educational infrastructure for developing skilled professionals in key fields. For example, Zambia has few schools for training doctors, nurses, and other health care workers. Its spending on education is low compared to other sub-Saharan countries.

Zimbabwe’s progress in reproductive, maternal, and child health has stagnated in recent years. According to a 2010 Demographic and Health Survey, contraceptive use, the number of births attended by skilled practitioners, and child mortality have either stalled or somewhat deteriorated since the mid-2000s. Zimbabwe’s total fertility rate has remained fairly stable at about 4 children per woman for the last two decades, although an uptick in the urban birth rate in recent years has caused a slight rise in the country’s overall fertility rate. Zimbabwe’s HIV prevalence rate dropped from approximately 29% to 15% since 1997 but remains among the world’s highest and continues to suppress the country’s life expectancy rate. The proliferation of HIV/AIDS information and prevention programs and personal experience with those suffering or dying from the disease have helped to change sexual behavior and reduce the epidemic.

Historically, the vast majority of Zimbabwe’s migration has been internal – a rural-urban flow. In terms of international migration, over the last 40 years Zimbabwe has gradually shifted from being a destination country to one of emigration and, to a lesser degree, one of transit (for East African illegal migrants traveling to South Africa). As a British colony, Zimbabwe attracted significant numbers of permanent immigrants from the UK and other European countries, as well as temporary economic migrants from Malawi, Mozambique, and Zambia. Although Zimbabweans have migrated to South Africa since the beginning of the 20th century to work as miners, the first major exodus from the country occurred in the years before and after independence in 1980. The outward migration was politically and racially influenced; a large share of the white population of European origin chose to leave rather than live under a new black-majority government.

In the 1990s and 2000s, economic mismanagement and hyperinflation sparked a second, more diverse wave of emigration. This massive out migration – primarily to other southern African countries, the UK, and the US – has created a variety of challenges, including brain drain, illegal migration, and human smuggling and trafficking. Several factors have pushed highly skilled workers to go abroad, including unemployment, lower wages, a lack of resources, and few opportunities for career growth.
