Africa: Introduction

This research paper provides a comprehensive geographic, political, and socio-economic introduction to Africa, detailing its physical landscape, colonial history, administrative structures, and immense cultural and linguistic diversity.

• Africa is the world's second-largest continent, covering approximately 30.37 million km² (about 20% of Earth's land area). Its geography is characterized by extremes, including the Sahara Desert—the world's largest hot desert at 8.6-9 million km²—and the Congo Basin rainforest, which is the planet's second-largest at roughly 3 million km².
• The continent's modern political structure consists of 54 internationally recognized sovereign countries, most of which are legacies of European colonial partitioning during the late 19th-century "Scramble for Africa." Only Ethiopia and Liberia avoided colonial rule in the early 20th century. South Sudan is the most recent addition, gaining independence in 2011.
• Africa is the least economically affluent major region globally, with a high concentration of low-income countries. In 2023, the World Bank classified 22 African countries as low-income, representing nearly 41% of the continent's states and over 80% of all low-income states worldwide. Only Seychelles is classified as a high-income economy.
• The continent possesses unparalleled linguistic diversity, with an estimated 1,500 to 3,000 languages belonging to four major families: Afro-Asiatic, Niger-Congo (the largest), Nilo-Saharan, and Khoisan. Due to colonial history, European languages remain official in many states, with English used in 23 countries and French in 21.
• Africa is ethnically diverse, with over 3,000 distinct ethnic groups. Most nations are not ethnically homogeneous; for example, Nigeria has over 250 ethnic groups, DR Congo has over 200, and Tanzania has more than 100. Colonial borders often split ethnic groups or grouped disparate peoples together, which has contributed to some post-independence conflicts.
• Religious composition is dominated by Christianity (roughly 45%) and Islam (roughly 40%), with significant adherence to indigenous traditional beliefs. Distribution generally follows geography, with Islam predominating in North Africa and the Sahel, and Christianity predominating in sub-Saharan Africa, except in the Horn and parts of West Africa.
