This work explores the relationship between class, ethnicity and space in Temuco, the city with the highest concentration of Mapuche indigenous people in Chile. Using the model of Erikson and Goldthorpe (1992), the location of Mapuche and non-Mapuche people from different social classes is described. The results indicate that Mapuche and non-Mapuche individuals share spaces when both belong to qualified manual classes, while they differ spatially when individuals take part in non-manual and non-qualified classes. The results are important to observe the processes of socio-spatial fragmentation in intercultural cities.
