Has middle-class income growth come almost entirely from women working more?
Core argument: Roughly 90% of U.S. middle-class income growth from 1979 to 2018 came from higher female wages and work hours, with male earnings contributing -4% and non-labor income 13%.
From 1979 to 2018, ~90% of middle-class income growth was driven by increased female wages and work hours. The fraction of dual-earner couples rose from ~50% to 70%, with significant growth among couples where both parents work full-time. The average middle-class married couple with children now works 3,446 hours annually, up by over 600 hours since 1975. If women's earnings had remained at 1979 levels, family income growth would have been just 2%, compared to the actual 21%. Male earnings contributed negatively to income growth at -4%, while non-labor income sources accounted for 13%. The average American worker now works ~1,860 hours per year, 300 more than in France, highlighting the increased work burden on families. This shift underscores the critical role of women's economic contributions in sustaining middle-class income growth amidst stagnant male earnings and stable work hours.







Ed Comment:Presumably the contribution of women is the difference between 58,502 and 66,096 I’m not sure I understand who/what contributed the difference between ($57,420 and $58,502) and ($66,096 and $69,559).
