note: on 14 February 2021, the Guinea government declared an outbreak of Ebola in N'Zerekore; the Centers for Disease Control and Prevention has issued a Travel Advisory recommending travelers avoid non-essential travel to Guinea; travelers to this area could be infected with Ebola if they come into contact with an infected person's blood or other body fluids; travelers should seek medical care immediately if they develop fever, muscle pain, sore throat, diarrhea, weakness, vomiting, stomach pain, or unexplained bleeding or bruising during or after travel
Food insecuritysevere localized food insecurity: due to high food prices - about 1.76 million people are estimated to be severely food insecure during the June-August 2021 period on account of high food prices and low purchasing power, resulting in acute constraints on households' access to food; the main drivers of the food insecurity are the effects of adverse weather events (flooding), Fall Armyworm attacks on maize in some localized areas, high inflation rate, weakening local currency and the effects of the COVID-19 pandemic restrictions (2021)severe localized food insecurity: due to localized shortfalls of cereal production - despite overall favorable food security conditions, the most vulnerable households still need external food assistance; the aggregate number of severely food insecure people was estimated at 267,000 during the lean season between June and August 2020;  it is very likely that the number of food insecure population increased with the impact of COVID-19 (2021)

Demographic profile

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.

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.
