Abstract

Throughout human societies, the separation of people into different social groups has persisted over time and is linked to various social problems. Concerns about the stability of democratic systems have risen in many nations due to reports of increasing political divisions along geographic lines. Employing advanced techniques in spatial data analysis, this project aims to gauge the extent of partisan segregation among registered voters in the United States. By measuring the residential and mobility patterns of individuals across the United States, and their partisan affiliations, this project will reveal patterns of partisan segregation (and potential polarization) more or less salient than those expected if partisans were not sorting based on political homogeneity.
