BROOKLYN - The U.S. Census Bureau released its 2010 data on the nation's population today, prompting city leaders to question whether the survey lost count of thousands of New Yorkers.

The 2010 census put New York City's population at just under 8.2 million people. That means the population has only increased by 167,000 people, or 2.1 percent, since the last census was taken in 2000.

Mayor Michael Bloomberg said the modest gains by the city just don't add up. He suggested the low count could be attributed to difficulties by census workers in tracking down recent immigrants.

City officials say an inaccurate count could mean disproportionate representation in Albany and Washington. It could also lower the amount of federal funding the city receives for various programs.

Here in Brooklyn, the new data shows the population has grown only by about 1.6 percent, to just over 2.5 million people.
