Africa is the second-largest continent, after Asia, in both size and population; it is located south of Europe and bordered to the west by the Atlantic Ocean and to the east by the Indian Ocean at about 30.2 million km² (11.7 million sq mi) including adjacent islands, it covers 6% of the Earth’s total surface area and 20.4% of the total land area. With 1.0 billion people (as of 2009, see table), Africa accounts for about 14.72% of the world’s human population. A large chunk of the world’s population if you ask me, a very big market indeed
