Based on the changes that took place in both labour market and the morphology of cities in most of Latin-American countries since the 1980s, this paper aims to contribute to the theoretical and analytical efforts regarding the impact of urban segregation on the quality of the insertion of individuals in the labour market. With data from the 1991 and 2001 National Censuses of Population, the magnitude and evolution of socioeconomic residential segregation in one intermediate city of Argentina (Córdoba) are calculated. Homogeneous areas are identified considering the education of household heads. Then, the effects of segregation on the quality of labour insertion are explored by running a logistic regression model.
