Coloureds ( or , ) refers to members of multiracial ethnic communities in Southern Africa who may have ancestry from more than one of the various populations inhabiting the region, including African, European, and Asian. South Africa's Coloured people are regarded as having some of the most diverse genetic background. Because of the vast combination of genetics, different families and individuals within a family may have a variety of different physical features. Coloured was a legally defined racial classification during apartheid referring to anyone not white or not a member of one of the aboriginal groups of Africa on a cultural basis, which effectively largely meant those people of colour not speaking any indigenous languages. In the Western Cape, a distinctive Cape Coloured and affiliated Cape Malay culture developed. In other parts of Southern Africa, people classified as Coloured were usually the descendants of individuals from two distinct ethnicities. Genetic studies suggest the group has the highest levels of mixed ancestry in the world. Mitochondrial DNA studies have demonstrated that many maternal lines of the Coloured population are descended from African Khoisan women. Coloureds are mostly found in the western part of South Africa. In Cape Town, they form 45.4% of the total population, according to the South African National Census of 2011. The apartheid-era Population Registration Act, 1950 and subsequent amendments, codified the Coloured identity and defined its subgroups. Indian South Africans were initially classified under the act as a subgroup of Coloured. As a consequence of Apartheid policies and despite the abolition of the Population Registration Act in 1991, Coloureds are regarded as one of four race groups in South Africa. These groups (blacks, whites, Coloureds and Indians) still tend to have strong racial identities and to classify themselves and others as members of these race groups. The classification continues to persist in government policy, to an extent, as a result of attempts at redress such as Black Economic Empowerment and Employment Equity. Background The Cape Coloured community is predominantly descended from numerous interracial sexual unions, primarily between Western European men and Khoisan or mixed-race women in the Cape Colony from the 17th century onwards. In KwaZulu-Natal, the Coloured possess a diverse heritage including British, Irish, German, Mauritian, Saint Helenian, Indian, Xhosa and Zulu. Zimbabwean Coloureds are descended from Shona or Ndebele, British and Afrikaner settlers, as well as Arab and Asian people. Griqua, on the other hand,
