The Republic of South Africa is a country located at the southern tip of Africa, with a 2,798 kilometres (1,739 mi) coastline on the Atlantic and Indian Oceans.[9] To the north lie Namibia, Botswana and Zimbabwe; to the east are Mozambique and Swaziland; while Lesotho is an independent country wholly surrounded by South African territory.[10]
South Africa is known for a diversity in cultures and languages. Eleven official languages are recognised in the constitution.[9] Two of these languages are of European origin: Afrikaans, a language which originated mainly from Dutch that is spoken by the majority of white and Coloured South Africans, and South African English. Though English has a large role in public and commercial life, it is nevertheless only the fifth most-spoken home language.[9]
South Africa is ethnically diverse. About 79.5% of the South African population is of black African ancestry,[4] divided among a variety of ethnic groups speaking different Bantu languages, nine of which have official status.[9] South Africa also contains the largest European, Asian, and racially mixed communities in Africa. About a quarter of the population is unemployed[11] and lives on less than US $1.25 a day.[12] South Africa is the most populous country in the world to have legalised same-sex marriage throughout its entire territory.
South Africa is a constitutional democracy in the form of a parliamentary republic with a parliamentarily dependent head of state. It is one of the founding members of the African Union, and has the largest economy of all the members. It is also a founding member of the United Nations and NEPAD. South Africa is a member of the Commonwealth of Nations, Antarctic Treaty System, Group of 77, South Atlantic Peace and Cooperation Zone, Southern African Customs Union, World Trade Organization, International Monetary Fund, G20 and G8+5.
