Abstract: Residential racial and class segregation produce or exacerbate distributive injustice and political exclusion. Integration as the dispersal of a concentrated minority among the majority, however, often has its own harmful consequences. An alternative ideal of differentiated solidarity combines positive affinity grouping with non-discrimination and regional government that encourages attention to shared problems and inequality.
