<Tr> <Td_colspan="2"> Abolition of Racially Based Land Measures Act, 1991 </Td> </Tr> <Tr> <Td_colspan="2"> Status: Repealed </Td> </Tr> <P> Group Areas Act was the title of three acts of the Parliament of South Africa enacted under the apartheid government of South Africa . The acts assigned racial groups to different residential and business sections in urban areas in a system of urban apartheid . An effect of the law was to exclude non-Whites from living in areas which were restricted to Whites (e.g., Sea Point, Lansdowne, Cape Town, Claremont). It caused many non-Whites to have to commute large distances from their homes in order to be able to work . The law led to non-Whites being forcibly removed for living in the "wrong" areas . The non-white majority were given much smaller areas (e.g., Tongaat, Grassy Park) to live in than the white minority who owned most of the country . Pass Laws required that non-Whites carry pass books, and later' reference books' (similar to passports) to enter the' white' parts of the country . </P> <P> The first Group Areas Act, the Group Areas Act, 1950 was promulgated on 7 July 1950, and it was implemented over a period of several years . It was amended by Parliament in 1952, 1955 (twice), 1956 and 1957 . Later in 1957 it was repealed and re-enacted in consolidated form as the Group Areas Act, 1957, which was amended in 1961, 1962, and 1965 . In 1966 this version was in turn repealed and re-enacted as the Group Areas Act, 1966, which was subsequently amended in 1969, 1972, 1974, 1975, 1977, 1978, 1979, 1982, and 1984 . It was repealed (along with many other discriminatory laws) on 30 June 1991 by the Abolition of Racially Based Land Measures Act, 1991 . </P>
