Finance - Wealth Distribution (CONGRESS OF THE UNITED STATES, CONGRESSIONAL BUDGET OFFICE)
For the 1 percent of the population with the highest income, average real after-tax household income grew by 275 percent between 1979 and 2007 (see Summary Figure 1).
For others in the 20 percent of the population with the highest income (those in the 81st through 99th percentiles), average real after-tax household income grew by 65 percent over that period, much faster than it did for the remaining 80 percent of the population, but not nearly as fast as for the top 1 percent.
For the 60 percent of the population in the middle of the income scale (the 21st through 80th percentiles), the growth in average real after-tax household income was just under 40 percent.
