Congressional Budget Office, Trends in the Distribution of Household Income Between 1979 and 2007 (Oct. 2011):
After-tax income for the highest-income households grew more than it did for any other group. (After-tax income is income after federal taxes have been deducted and government transfers—which are payments to people through such programs as Social Security and Unemployment Insurance—have been added.) CBO finds that, between 1979 and 2007, income grew by:
- 275% for the top 1% of households
- 65% for the next 19%
- 40% for the next 60%
- 18% for the bottom 20%
