[4] In the year 2005, there were approximately 113,146,000 households in the United States. 19.01% of all households had annual incomes exceeding $100,000,
[5] 12.7% fell below the
federal poverty threshold[6] and the bottom 20% earned less than $23,202.
[7] The aggregate income distribution is highly concentrated towards the top, with the top 6.37% earning roughly one third of all income, and those with upper-middle incomes control a large, though declining, share of the total earned income.
[8][2] Income inequality in the United States, which had decreased slowly after
World War II until 1970, began to increase slowly in the 1970s, and has increased more quickly since then.
[9] Households in the top
quintile, 77% of which had two income earners, had incomes exceeding $91,705. Households in the mid quintile, with a mean of one income earner per household had incomes between $36,000 and 57,657.
