Africa facts: 54 countries, 2nd-largest continent

Africa at a glance

Africa facts start with scale: it is the world’s second-largest and second-most populous continent after Asia. It covers around 20% of Earth’s land area and about 6% of the planet’s total surface area, while straddling both the equator and the prime meridian.

That position gives Africa a geographic reach that crosses the center lines of the globe. It is also home to 54 fully recognised sovereign states, with Algeria the largest country by area and Nigeria the largest by population.

Which continent has the youngest population?

Africa does. Its population is the youngest among the continents, and it is expected to exceed 3.8 billion people by 2100.

That demographic profile sits beside another striking fact: Africa is the least wealthy inhabited continent per capita and the second-least wealthy by total wealth. Those numbers help explain why the continent appears so often in global discussions of development, migration, and economic change.

Where did humans begin?

Africa is widely accepted as the place of origin of humans and the great apes. Homo sapiens are believed to have originated there between 350,000 and 260,000 years ago.

That long timeline sits behind the continent’s role in human history. From the beginning of our species to the present, Africa has remained central to the story of human origins.

What makes Africa so important in nature and climate?

Africa is the continent with the largest number of megafauna species, a fact that places elephants, giraffes, rhinos, and many other large animals in the broader picture of its landscapes and ecosystems.

It is also identified as the continent most vulnerable to climate change. That combination of biological richness and climate exposure makes Africa’s environmental story especially significant.

How is Africa governed and connected?

The African Union is headquartered in Addis Ababa, giving the Ethiopian capital a major place in continental politics and diplomacy.

With 54 sovereign states, Africa is made up of many countries, regions, and peoples, but it is also tied together by shared institutions and geography. Its scale, population, and history make it one of the most important continents to understand.
