South Africa, officially the Republic of South Africa (RSA), is the southernmost country in Africa. It is bounded to the south by 2798 km of coastline that stretch along the South Atlantic and Indian Oceans; to the north by the neighbouring countries of Namibia, Botswana, and Zimbabwe; and to the east and northeast by Mozambique and Eswatini. It also completely enclaves the country Lesotho. It is the southernmost country on the mainland of the Old World, and the second-most populous country located entirely south of the equator, after Tanzania. South Africa is a biodiversity hotspot, with unique biomes, plant and animal life. With over 60 million people, the country is the world's 24th-most populous nation and covers an area of 1221037 km2. South Africa has three capital cities, with the executive, judicial and legislative branches of government based in Pretoria, Bloemfontein, and Cape Town respectively. The largest city is Johannesburg.
About 80% of the population are Black South Africans. The remaining population consists of Africa's largest communities of European (White South Africans), Asian (Indian South Africans and Chinese South Africans), and multiracial (Coloured South Africans) ancestry. South Africa is a multiethnic society encompassing a wide variety of cultures, languages, and religions. Its pluralistic makeup is reflected in the constitution's recognition of 11 official languages, the fourth-highest number in the world. According to the 2011 census, the two most spoken first languages are Zulu (22.7%) and Xhosa (16.0%). The two next ones are of European origin: Afrikaans (13.5%) developed from Dutch and serves as the first language of most Coloured and White South Africans; English (9.6%) reflects the legacy of British colonialism and is commonly used in public and commercial life.
