Abstract
In common with many other Third World cities, the periphery of San Carlos de Bariloche includes settlements that are not fully integrated into the city. In this paper, the author considers how to identify the settlements and the groups in greatest need within the city and how to develop a set of social indicators for unsatisfied basic needs. The paper includes an historical account of the development of low-income settlements in San Carlos de Bariloche and their changing location. A later section analyzes the changes between 1980 and 1991 in unsatisfied basic needs in regard to housing conditions and education for different groups, according to their place of birth.
