Even with more women settling into the role of family breadwinner, the gender pay gap only rarely settles in their favor. Today, 23 percent of women earn more than their husbands, up from 4 percent who did in 1960, according to a Pew Research Center study released this week. But that’s not necessarily an indication that women are earning more. Comparing full-time, year-round workers, women earn 77 cents for every dollar men earn, said Dana Britton, director of the Center for Women and Work at Rutgers University in Newark, N.J. In 1960, the gap was about 61 cents to the dollar.
