Africa

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 around 20% of Earth's land area and 6% of its total surface area. With nearly 1.4 billion of the world's population, Africa's population is the youngest among the continents; the median age in 2012 was 19.7, when the worldwide median age was 30.4. Based on 2024 projections, Africa's population will exceed 3.8 billion people by 2100. Africa is the least wealthy inhabited continent per capita and second-least wealthy by total wealth, ahead of Oceania. Scholars have attributed this to various factors including geography, climate, corruption, colonialism, the Cold War, and neocolonialism. Despite this low concentration of wealth, the African economy is home to many of the world's fastest-growing economies.
