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."
本文研究了南非的人口迁移和城市化模式差异。“有迹象表明，作为低收入群体的黑人在比勒陀利亚-威特沃特斯兰德-瓦尔三角都市圈（PWV）的核心区域所占比例在相应增加，而作为高收入群体的白人所占比例在相应减少，在其他区域情况则相反……本文呈现的研究结果重申了[政府政策的不足之处]，并强调有必要改变PWV目前的官方空间政策。”
