East Africa, also known as Eastern Africa or the East of Africa, is a region at the eastern edge of the African continent, distinguished by its geographical, historical, and cultural landscape. Defined in varying scopes, the region is recognized in the United Nations Statistics Division scheme as encompassing 18 sovereign states and 4 territories.

Africa is the world's second largest and second-most populous continent after Asia. At about 30.3 million km2 including adjacent islands, it covers 20% of Earth's land area and 6% of its total surface area. With 1.4 billion people as of 2021, it accounts for about 18% of the world's human population. Africa's population is the youngest amongst all the continents; the median age in 2012 was 19.7, when the worldwide median age was 30.4. Despite a wide range of natural resources, Africa is the least wealthy continent per capita and second-least wealthy by total wealth, ahead of Oceania. Scholars have attributed this to different factors including geography, climate, tribalism, colonialism, the Cold War, neocolonialism, lack of democracy, and corruption. Despite this low concentration of wealth, recent economic expansion and the large and young population make Africa an important economic market in the broader global context.
