South Africa is known for its diversity of cultures, languages and religious beliefs, which is why it is known as the rainbow nation. Eleven languages are recognized as official by the Constitution of South Africa. Two of the eleven languages are of European origin: Afrikaans, a language that comes directly from Dutch and is spoken by the majority of the white and mestizo population, and English.

South Africa is an ethnically diverse country. 79.5% of the South African population is black, which is divided into different ethnic groups that speak different Bantu languages, nine of which are official. It also has the largest communities of inhabitants of European and Indian origin, as well as multiracial communities on the continent.
