How Your Social Class Affects Where You'll Move

Socioeconomic sorting at the metropolitan level is making America more polarized, an economist finds.

The Sunbelt is growing, the Rust Belt is dying, and the only thing keeping expensive coastal cities afloat is international immigration, as American-born residents flee their escalating housing prices.

That pretty much sums up the conventional wisdom about the recent growth and decline of U.S. cities. And that conventional wisdom was only reinforced last month when the Census Bureau released its latest figures on population growth for America’s metropolitan areas. Nine of the top 10 counties with the largest numeric increase in population last year were in the Sunbelt, with the one exception being King County, where Seattle is located.
