Income Gap Is Widening, Data Shows

By DAVID CAY JOHNSTON

Income inequality grew significantly in 2005, with the top 1 percent of Americans — those with incomes that year of more than $348,000 — receiving their largest share of national income since 1928, analysis of newly released tax data shows.

The top 10 percent, roughly those earning more than $100,000, also reached a level of income share not seen since before the Depression.

While total reported income in the United States increased almost 9 percent in 2005, the most recent year for which such data is available, average incomes for those in the bottom 90 percent dipped slightly compared with the year before, dropping $172, or 0.6 percent.
