“E pluribus unum” — out of many, one — is one of America’s traditional mottos. And you might think it would be reflected in reality. We aren’t, after all, just united politically. We share a common language; the unrestricted movement of goods, services and people is guaranteed by the Constitution. Shouldn’t this lead to convergence in the way we live and think?
In fact, however, the past few decades have been marked by growing divergence among regions along several dimensions, all closely correlated. In particular, the political divide is also, increasingly, an economic divide. As The Times’s Tom Edsall put it in a recent article, “red and blue voters live in different economies.”
What Edsall didn’t point out is that red and blue voters don’t just live differently, they also die differently.
About the living part: Democratic-leaning areas used to look similar to Republican-leaning areas in terms of productivity, income and education. But they have been rapidly diverging, with blue areas getting more productive, richer and better educated. In the close presidential election of 2000, counties that supported Al Gore over George W. Bush accounted for only a little over half the nation’s economic output. In the close election of 2016, counties that supported Hillary Clinton accounted for 64 percent of output, almost twice the share of Trump country.
