The Numbers Behind The Big Flip

This is why we're making The Big Flip.




  • Mothers are breadwinners in 40% of American families. 1
  • The number of stay-at-home dads in the U.S. has doubled since 1989. 2
  • Women are projected to not just close the income gap—but to out-earn men on average by 2028. 3In other words, the big flip will be the new normal.


  • Husbands whose wives make more money are 61% less happy. 4
  • Wives who are primary breadwinners are also significantly less happy about their family lives than other women. 5
  • Men are 5 times more likely to cheat when financially dependent on their wives. 6
  • Divorce is 40% more likely when a woman makes over 60% of the family’s income. 7


  • 51% of Americans still think that kids are better off with mom at home than at work. 1
  • Only 8% of Americans think that kids are better off with dad at home than at work. 1
