D.C.’s a Transient Place–And That’s A Good Sign
But the Washington area should be awfully glad the transience numbers don't run the other way. Rock star urbanist Richard Florida (yeah, yeah, yeah) has long hammered on the benefits of mobility, and the latest data have only led him to double down on the thesis, characterizing states as either "stuck" or "unstuck." Running the numbers against other demographic indicators, he finds that transience is positively correlated with diversity, lower poverty rates, better education, higher income, less smoking and obesity, and more happiness. (Interestingly, though, there's apparently no correlation between transience and employment, which is hard to explain in the Floridian paradigm—people are supposed to move to opportunity, not just for the hell of it).
Of course, the usual scientific caveat applies: It's hard to say that these transient states are more happy because people have moved in and out of them. It's just as likely that having that kind of cultural capital is also what allows them to pick up and make a life somewhere else. Regardless, having lots of people born somewhere else should be viewed as an indicator of regional health, even if we don't all root for the Redskins.
