UPDATE 1-Mothers are breadwinners for growing share of U.S. families | Reuters: The so-called "breadwinner moms" are split into two camps, with married mothers who have a higher income than their husbands accounting for 37 percent and 63 percent consisting of single mothers, the Pew study said.
It said married women who out-earn their husbands tended to be slightly older, disproportionately white and college-educated and much better paid than single mothers, who were younger, more likely to be black or Hispanic and less likely to have a college degree.
Single mothers now make up one-quarter of all U.S. households with children and women make up almost half of the U.S. labor force.
According to the Pew study, the employment rate of married mothers with children has jumped from 37 percent in 1968 to 65 percent in 2011.
In a public opinion survey examining the impact of mothers working for pay, Pew Research found last month that about two-thirds of Americans recognized clear economic benefits for families in the gains moms have made in the workplace.
But the survey found that 74 percent of adults said the increasing number of women working for pay had made it more difficult for parents to raise children, and half said it made it harder for marriages to succeed.
