The change of government in South Africa and the subsequent implementation of the Reconstruction and Development Programme (RDP) has necessitated afresh look at the spatial‐economic development policies of the past. Recently, an attempt was made to measure differences in existence level in South Africa using a combination of First and Third World criteria. In this paper these differences are related to general trends in population redistribution in the country since 1960 in an effort to assess the probable impact of existence level difference and migration on urbanisation in South Africa in the long run. On the basis of these assessments, expected trends in urban development in South Africa are compared with previous industrial development policies in an effort to determine RDP imperatives for the future.
