From the NY Times:
As for metropolitan New York over all, about 110,000 more people moved out last year than moved in from elsewhere in the United States, according to the estimate, which is made on the basis of projected growth rates since the 2000 census.
Only two years earlier, the loss was twice as high, and in the middle of the decade it approached 300,000 annually. In New York City, the loss was 77,000 last year compared with 171,000 in 2005.
The shrinking migration deficit reflected several factors. The city is considered a more attractive place to live, and fewer retirees may be leaving it because they delayed retirement after the recession took a toll on their savings or they were unable to sell their homes.
The city registered a net gain of 57,000 immigrants from abroad, down from the decade’s peak of 94,000 from 2000 to 2001. The decline mirrored a national trend.
In Queens, for the first time this decade, more people moved in — either from elsewhere in the country or from abroad — than moved out.
