The dynamics of residential segregation in Italy are an emerging issue of interethnic coexistence. This article presents the contribution of Schelling on this topic. In XX century, several authors developed a number of segregation indices. Schelling proposed to study residential segregation using a linear model and a checkerboard model. The metaphor of the line allows to have an unlimited sequence of symbols, and the metaphor of the checkerboard introduces restrictions on the neighbourhoods, with its edges and its corners. The continuing vitality of Schelling’s thought for the study of social segregation in cities mainly depends on his discoveries about the unexpected relationships between individual residential choices and aggregate neighbourhood segregation. So, an integrated city can lead to segregation even if no individual agent prefers the resulting segregation. All that raises serious doubts about the real possibility of public policies to pursue the residential integration by promoting openness and tolerance of diversity.
