@KatherineGuyot ~90% of middle-class income growth btw 1979-2018 driven by higher female wages & hours worked. The average middle-class married couple with children now works 3,446 hours annually, up by over 600 hours since 1975.

“…. The stability of average work hours combined with the increasing proportion of couples who are dual earners means that families are collectively putting in more work hours now than in the recent past…. The average American worker currently works an estimated 1,860 hours per year, nearly 300 more than workers in France and 400 more than those in the Netherlands…..The fraction of couples who are dual earners has risen from about half to 70% over the last four decades. The largest increase within this category has been among couples in which both the mother and the father work full-time. The average middle-class married couple with children now works a combined 3,446 hours annually, an increase of more than 600 hours—or 15 additional weeks of full-time work—since 1975…. Using a similar strategy, we estimate that if women’s average earnings dropped back to their 1979 levels, average middle-class family incomes would have grown by only 2% between 1979 and 2018 (Figure 2.5).Average family income actually grew by 21% over this period. This analysis counts single adults as their own families and includes those without children. Due to declines in male work hours per family, the contribution of total male earnings to middle-class income growth was a net negative at -4%. Non-labor income sources were responsible for 13% of income growth.This leaves by far the majority of middle-class income gains to women. We estimate that 29% of average income growth is attributable to higher female work hours and 63% to higher female pay per hour. To summarize, about 90 percent of middle-class families’ income growth over this period was due to women’s contributions….”
They define middle class“…as the middle 60% of the family income distribution. We weight each family unit in the distribution by family size so that themiddle class contains approximately 60% of peoplerather than 60% of families….”
They also find that 90% of middle class income growth btw 1979-2018 has been driven by increases in women’s hours worked and women’s wages
Brookings finds that a steady decline in working hours over recent decades has leveled off in the US, American workers work ~ 1860 hours a year, 300 more hours than in France

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).
