The Population Registration Act of 1950 required that each inhabitant of South Africa be classified and registered in accordance with their racial characteristics as part of the system of apartheid.
Social rights, political rights, educational opportunities, and economic status were largely determined by the group to which an individual belonged. There were three basic racial classifications under the law: Black, White and Coloured (mixed). Indians (that is, South Asians from the former British India, and their descendants) were later added as a separate classification as they were seen as having "no historical right to the country".
An Office for Race Classification was set up to overview the classification process. Classification into groups was carried out using criteria such as outer appearance, general acceptance and social standing. For example, it defined a "white person" as one who "in appearance is obviously a white person who is generally not accepted as a coloured person, or is generally accepted as a white person and is not in appearance obviously a white person." Because some aspects of the profile were of a social nature, reclassification was not uncommon, and a board was established to conduct that process.
