title: Urban change in the third world:  are recent trends a useful pointer to the urban future?
abstract: "This paper has three aims.  The first is to examine the reliability of the data base for the statistics which are used as the basis for commenting on urban change in 'the Third World'.  The second is to explore whether valid generalisations about urban change can be made for the Third World.  And the third is to examine the validity of United Nations projections for the Third World's urban future."
