The changes experienced by cities are related to the restructuring of the labor market and the consequent emergence of new social classes. These groups, motivated by spatial preferences, transform urban spaces. This paper explores the spatial transformations of classes in the city of Temuco (Chile) between 1992 and 2002. Leaving aside the traditional indicators of residential segregation and overcoming de-territorialization in social stratification models, important changes are observed in the city. Among them, a peri-urban encounter between very different classes, former worker zones that rise in the socio-spatial scale, and the spatial diversification of the ascending middle class.
