Do household size and composition understate US income gains?
Core argument: Real median US household income rose 2.7% between 1999 and 2018, but adjusting for the decline in average household size to 2.52 persons lifts median income per household member to 5.9%.
Between 1999 and 2018, real median household income increased by only 2.7%, but when adjusting for the decline in average household size to 2.52 persons, median income per household member rose by 5.9%. This adjustment highlights more robust income growth than the unadjusted figures suggest. For households with a fixed number of earners, the data is even more positive: one-earner households saw a 7.6% increase in real median income, nearly three times the overall household increase, while two-earner households experienced a 12% rise, more than four times the overall rate. These statistics underscore the importance of considering household size and composition when evaluating income trends, offering a more optimistic view of economic progress for US households.
