Analysis by Sentier Research of U.S. census data shows U.S. median household income declined from $54,983 in Jan. 2009 to $50,964 in June 2012, adjusted for inflation. This is $4019 in lost real income. The decline is 8% from $55,470 in 2000 before the burst of the dot come bubble. Some of this is because of trends of smaller family, lower fertility rates and more Americans living alone. But as a look at the figures in this research by Catherine Rampell of the NYT, 8/23/2012 shows, the losses in income affects all demographics, hit blacks and people with some education like a high school diploma but no degree the hardest, and also reflects the persistence of long tem unemployment which lowers income.
