Africa is the second-largest continent in the world in both area and population. It is an almost entirely isolated landmass with only a small land bridge in the northeast, connecting the African Mainland with Western Asia.
Africa covers six percent of the world's total surface area, roughly 30,244,000 km² (11,700,000 mi²). Including its adjacent islands, the continent occupies about 20 percent of Earth's total land area. Africa's largest country is Algeria, followed by the Democratic Republic of the Congo (Kinshasa), and Sudan.
