Africa is the world's second-largest and second most-populous continent, after Asia. At about 30,221,532 km² (11,668,545 mi²) including adjacent islands, it covers 6.0% of the Earth's total surface area, and 20.4% of the total land area.[1] With more than 950,000,000 people in 61 territories, it accounts for about 14% of the world's human population. The continent is surrounded by the Mediterranean Sea to the north, the Suez Canal and the Red Sea to the northeast, the Indian Ocean to the southeast, and the Atlantic Ocean to the west. There are 46 countries including Madagascar, and 53 including all the island groups.
