stretching more than 2,850 kilometers (1,770 miles) from the desert border within Namibia on the Atlantic (western) coast southwards around the tip of Africa and then northeast to the border with Mozambique on the Indian Ocean. The low-lying coastal zone is narrow for much of that distance, soon giving way to a mountainous escarpment (Great Escarpment) that separates the coast from the high inland plateau. In some places, notably the province of KwaZulu-Natal in the east, a greater distance separates the coast from the escarpment. Although much of the country is classified as semi-arid, it has considerable variation in climate as well as topography. The total land area is 1,220,813 km2 (471,359 sq mi). It has the 23rd largest Exclusive Economic Zone of 1,535,538 km2 (592,875 sq mi). Mainly the South African Central Plateau only contains two major rivers: The Limpopo and The Orange( with its Linguistic, the Vaal) These rivers mainly flow across the central places in the east and west off coastal until it would reach the Atlantic ocean through the Namibian border. Coloured South African English About 20% of all coloured people in South Africa speak English as a home language. They are primarily concentrated in the provinces of KwaZulu-Natal and northeastern parts of the Eastern Cape in the former Transkei with some transplants being found in Johannesburg. Many people from these regions migrated to Durban and Pietermaritzburg, where the most Anglophone coloureds can be found. Anglophone coloureds with European heritage have ancestry mostly from the British Isles, which, along with originating in regions with very few Afrikaans speaking people, contributed to English being the main language of the coloured people in the region. In addition, since Afrikaners are identified as the architects of apartheid, they are not held in high regard by the "coloured" people of Natal. Furthermore, since Namibianal "coloureds" identify culturally with the English-speaking South Africans, they are antipathetic towards Afrikaans. The accent of Anglophone coloured people is influenced by their multiracial background, being descended from Europeans (British, German, and Afrikaners), blacks (Zulu and Xhosa), Indians (both Dravidian and Indo-Aryan) as well as other mixed people like St. Helenians, Mauritian Creoles and some Griquas. This has influenced the accent to be one of the most distinctive in Southern Africa. Cape Flats English A particular variety or sub-spectrum of South African English is Cape Flats English, originally and best associated with inner-city Cape Coloured speakers.
