Nearly every state has seen a growing number of children living in families falling deeper into poverty and economic insecurity, says Reuters, citing a new study by the Annie E. Casey Foundation.

The youth advocacy group’s annual report on the state of the country’s children, released Wednesday, found that 15.7 million lived in poverty in 2010, up from 13.3 million in 2005, indicating a significant, long-term impact from the 2007-9 recession and the slow recovery.

While many states have seen gains in education and health indicators, most have a rising number of children whose parents lack stable full-time employment and are burdened with high housing costs.

Children in the Northeast and Upper Midwest are faring best socially and economically, with those living in the Southeast and Southwest doing worst, the Casey study said.
