The dispersion of Black urban suburbs and homeland towns in South Africa for the period 1904 to 1975 is described by means of nearest neighbour analysis. These descriptions indicate a tendency towards a regular pattern for 1904 but with a continuous
trend towards clustering in the ensuing years till 1951. After 1951 however, the trend was reversed and a tendency towards randomness became apparent. The main forces responsible for the changing spatial pattern are indicated. During the period 1904-1951
