Race and Migration as a Source of Political Diversity and Homogeneity
A previous chapter demonstrated that the migration patterns within the United States differ by age cohort, which has political consequences because of the different voting patterns of Americans at different stages of their lives. Speciﬁ cally, we saw that, during the 1990s, the youngest cohort of adult Americans moved in massive numbers to those counties that now give overwhelming victories to Democratic presidential candidates. We further saw a greater number of older Americans left those counties than moved in, and they moved in substantial numbers to counties that now give overwhelming victories to the Republican Party in presidential elections. We further saw that the family formation trends within different communities are an important predictor of aggregate political outcomes, even when controlling for a myriad of other variables. High rates of marriage, particularly among young Americans, was a strong predictor of aggregate Republican voting.
