Implications of differential urbanization on deconcentration in the Pretoria-Witwatersrand-Vaal Triangle metropolitan area, South Africa.

Population migration and differences in urbanization patterns in South Africa are examined. "Indications are that the Blacks--a low-income group--are increasing proportionally, while the Whites--the highest-income group--are diminishing proportionally in the inner core zone of the Pretoria-Witwatersrand-Vaal Triangle metropolitan area (PWV), and vice versa in the other zones.... Study results presented in this paper reiterate [inadequacies of government policies] and stress the need for changes in the present official spatial policy for the PWV."
