Location Information
Africa is the world's second-largest and second-most populous continent after Asia. At about 30.3 million km2 (11.7 million square miles) including adjacent islands, it covers around 20% of Earth's land area and 6% of its total surface area. With nearly 1.4 billion people as of 2021, it accounts for about 18% of the world's human population. Africa's population is the youngest among all the continents; the median age in 2012 was 19.7, when the worldwide median age was 30. 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. According to the World Book Encyclopedia, Islam and Christianity are the two largest religions in Africa. Islam is most prevalent in Northern Africa, and is the state religion of many North African countries, such as Algeria, where 99% of the population practices Islam. The majority of people in most governments in Southern, Southeast, and Central Africa, as well as in a sizable portion of the Horn of Africa and West Africa, identify as Christians.
