Residential Segregation Multi-Scale Analyses Using Spatial Measures of Segregation This presentation is about multi-scale analyses using spatial measures of segregation. I will bring some case studies that demonstrate the importance of scale when we want to understand residential segregation, patterns of segregation and the impacts that these different patterns can have on cities. My interest for segregation measures and everything I talk about measures comes from the point of view of an urban planner, a Brazilian urban planner, who lives and thinks about cities with very strong disparities/inequalities. Disparities that materialize spatially in the cities, as the picture examplifies, with extremely poor areas, medium class areas, rich areas... They all consolidating this strong segregation among social groups.

Segregation Some studies show that most people prefer to live in a non-segregated society. Why there is so much segregation?

Segregation is an outcome of individual choices But high levels of segregation indicate mean that people are prejudiced?

Schelling’s Model of Segregation Schelling (1971) demonstrates a theory to explain the persistence of racial segregation in an environment of growing tolerance If individuals will tolerate racial diversity, but will not tolerate being in a minority in their locality, segregation will still be the equilibrium situation
