Western Sahara is a disputed territory on the northwest coast of Africa. About 20% of the territory is controlled by the Sahrawi Arab Democratic Republic (SADR); the remaining 80% is occupied and administered by neighboring Morocco. It has a surface area of 266,000 square kilometres (103,000 sq mi). It is the second most sparsely populated country in the world and most sparsely in Africa, mainly consisting of desert flatlands. The population is estimated at about 500,000, of which nearly 40% live in Morocco-controlled Laayoune, the largest city in Western Sahara.

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.
