We’ve updated our chart and table on how the change in income distribution between 1979 and 2007 affected different income groups to reflect a slightly different methodology. Below are the revised figures.
For example, the average middle-income American family had $13,000 less after-tax income in 2007, and an average household in the top 1 percent had $782,600 more, than they would have had if incomes of all groups had grown at an equal rate since 1979.
