Extended Data Fig. 6: Partisan Segregation vs. non-Hispanic White-only Partisan Segregation.

Distribution for non-Hispanic white voters (n = 115,736,045) of differences between partisan segregation calculated from all 1,000 nearest neighbors and partisan segregation calculated only from non-Hispanic white neighbors. Positive Isolation values means that a voter appears less isolated by partisanship when we look only at their non-Hispanic white neighbors. Positive Exposure values means that a voter appears to have less cross-party exposure when we only look at their white neighbors. Distributions are plotted separately for Democrats (blue) and Republicans (red). Solid lines represent mean values and dashed lines represent median values. Distributions are weighted by posterior partisan probabilities.
