Long Island, New York
Like California, New York is, historically, a major exporter of it citizens. The state depends upon foreign migration for its population growth. But also like California, New York's out-migration eased in the year ended July 1.
In 2006, nearly a quarter million more people left the state than moved in, two and a half times the 2009 total.
The state has not gone through the same housing crisis that engulfed bubble states. The unemployment rate is lower than the nation as a whole and foreclosure problems have been relatively minor.
Still, New York is the decade's biggest loser: The state a total of 1,686,583 residents, more than anywhere else.
