This is based on a 2006 report by the U.S. Census for a family of four.This figure is in the middle of the range of incomes for this section of the population. The median income during this time for all households was $48,561.n the 2000s, the middle class took a hit. From 2000 to 2010, income levels for those in the middle class decreased by 7 percent.
