A national trend has reversed.
When the U.S. economy slowed during the recession, so did one of the major demographic shifts of the last several decades. For a brief respite, the Northeast and Midwest stopped shedding quite so many residents to the burgeoning Sun Belt. That trend, though — which has big consequences for politics, among other things — has been picking back up. New census data shows the trend accelerating back to its pre-recession pace.
