By the Numbers

The top one percent of households received 21.8 percent of all pre-tax income in 2005, more than double what that figure was in the 1970s. (The top one percent's share of total income bottomed out at 8.9 percent in 1976.) This is the greatest concentration of income since 1928, when 23.9 percent of all income went to the richest one percent. The above figures include capital gains, which are strongly affected by the ups and downs of the financial markets. Excluding capital gains, the richest one percent claimed 17.4 percent of all pre-tax income in 2005, more than double what that figure was in the 1970s. (It bottomed out at 7.8 percent in 1973.) This is the greatest concentration of income since 1936, when the richest one percent received 17.6 percent of total income.)
