Source: Authors’ tabulation.
Note: Precinct-level Election Data, American Community Survey, n = 163,512 precinct years. Precinct-level election data come from the Florida Voting and Election Science Team, Tufts University Metric Geometry and Gerrymandering Group, and the New York Times. Each panel represents a separate regression including an independent variable for the percentage of the respective race group in the precinct. All regressions control for educational attainment, homeownership, the Democratic vote share of neighboring precincts, logged population, and state fixed effects. We use robust standard errors.
