Development typologies
In view of the differences in the formative processes and nature of squatter communities, a number of typologies have been derived in an attempt to understand this complexity. An early classification by Stokes (1962) distinguished between slums of hope and slums of despair, and implied that the success or otherwise of the community was largely in the hands of the squatters. A different approach identifies the changing needs of squatters and how their priorities change with different stages in their development. Turner (1969) proposed a threefold classification of individuals into bridgeheader, consolidator and status-seek, each corresponding to successive stages in income growth. This taxonomy assumes that as economic security increases, there is a revaluation of needs and priorities which is translated into housing preferences
