FiveThirtyEight has created data visualizations illustrating where Democrats and Republicans live in the 153 largest metro areas in the United States, highlighting distinct political polarization based on geography in many cities. The visualizations combines data about each voting precinct’s two-party margin in the 2016 presidential election with mapping data from OpenStreetMap. The visualizations show that population density correlates with more Democratic voters and that most cities exhibit partisan segregation, with large areas of distinctly Democrat- or Republican-leaning populations.
