Here's a chilling indicator of how nasty Connecticut's recession has been: the number of people living in poverty in the past three years increased in Bloomfield, Bridgeport, Norwalk, Shelton, Stamford, Wethersfield and Windham.

That's according to a new analysis by Connecticut Voices for Children of the latest U.S. Census data.

The advocacy group also found that Bloomfield, Danbury, East Haven, Norwalk and Stamford saw an increase in the number of children living below the federal poverty line in the past three years.

The federal poverty level for the continental United States is now $22,350 for a family of four, and the number of people living below that mark in Connecticut rose to 9.7 percent.

And as Connecticut's poverty has risen, there's been a corresponding drop in the statewide median income to $67,067.

All the numbers used in this analysis are three-year averages for 2008-2010 when compared to the three-year averages for the 2005-2007 period.

The census data released in late October shows that only one city or town in this state with a population of more than 20,000 saw its median income rise, and that lucky community was Fairfield. The town's mid-point income went from $108,693 for 2005-07 to an average of $117,178 for the past three years.

Median incomes in Berlin, Bloomfield, Enfield, New Milford, West Hartford and West Haven dropped in the past three years.

The community with the highest number of folks living in poverty was Windham, with 24.5 percent (up from 17.5 percent). Bridgeport was a close second, with 22.7 percent of its population living below that federal threshold.

East Haven and Norwalk are tied for having the highest level of childhood poverty, with 15 percent.
