During that same period, 31 states had increases in the percentage of people in poverty.
Meanwhile, nearly 20 percent reported incomes of $100,000 or more in 2009, down almost a percentage point from 2008.

In contrast, almost one in four families earned less than $25,000, an increase of 1 percentage point.
