Mothers are the primary breadwinners in four out of 10 U.S. households with minor children, a record number driven up by growing populations of single moms and married women who make more than their husbands, according to a report released Wednesday from the Pew Research Center. . . .
Disparities between the two groups are sharp. The married moms are more likely to be white, educated and older, making a median income of $50,000. While the unmarried mothers are frequently younger, either black or hispanic, and bringing in a median income of $20,000.
“The growth of both groups of mothers is tied to women’s increasing presence in the workplace,” the study states, pointing out that women make up 47 percent of the labor force and that more mothers work outside the home today: 65 percent according to 2011 census data, compared with 37 percent in 1968.
