New York will lose two congressional seats after 2010 Census data released Tuesday shows stagnant population growth.

The government released the results of the latest Census in Washington, and announced the re-allocation of House seats for the 2012 election.

New York's congressional delegation will drop from 29 to 27 – the smallest representation since 1823.

Numbers show the population of the country stands at just over 308,700,000. It's an increase of about 10 percent over the last Census, but is still the slowest growth over a decade since the Great Depression.

Much of that growth took place in western and southern states like Texas, which will gain four seats in the House of Representatives. Florida will gain two.

"If we look at the congressional apportionment each decade since 1940, the trend is a growth in seats for western and southern states, and a tendency to lose seats from the midwest and the northeastern states,” said Robert Groves of the U.S. Census Bureau.

New York, while still the third most-populous state, after California and Texas, ranked among the bottom five when it came to population growth over the last decade.

As a result, New York and Ohio will each lose two seats.

Other states also losing seats are: Illinois, Iowa, Louisiana, Massachusetts, Michigan, Missouri, New Jersey, Ohio and Pennsylvania.

Demographers like Andrew Beveridge say much of the population drain in New York lies upstate.

"There’s still actual population loss going on upstate. Up in western New York, but all the way over through what some people call northern Appalachia, including Ithaca," Beveridge said.

In New York City, where population growth has been relatively strong, the city is unlikely to lose any Congressional seats. But exactly which seats will be drawn out of existence is up to state lawmakers, who will begin the process of redrawing district lines early next year.
