Have incomes risen across all tiers while income gaps widened?
Core argument: Median income of middle-class U.S. households rose 60%, from about $66,400 in 1970 to $106,100 in 2022, in inflation-adjusted 2023 dollars scaled to a three-person household.
Households in all income tiers had much higher incomes in 2022 than in 1970, after adjusting for inflation. Gains for middle- and lower-income households were less than the gains for upper-income households. The median income of middle-class households increased from about $66,400 in 1970 to $106,100 in 2022, or 60%. Over this period, the median income of upper-income households increased 78%, from about $144,100 to $256,900. (Incomes are scaled to a three-person household and expressed in 2023 dollars.) The median income of lower income households grew more slowly than that of other households, increasing from about $22,800 in 1970 to $35,300 in 2022, or 55%. Consequently, there is now a larger gap between the incomes of upper-income households and other households. In 2022, the median income of upper income households was 7.3 times that of lower-income households, up from 6.3 in 1970. It was 2.4 times the median income of middle income households in 2022, up from 2.2 in 1970.
