A USA Today study found that 40 percent of households with children under the age of 18 have the mother as the sole or primary breadwinner.
This percentage is up from around just 11 percent in the 1960s.
Stephanie Bell, an associate attorney at Blitz, Bardgett and Deutsch LC in Jefferson City, says this is a step in the right direction for equality for women in the workplace.
"A lot of research has been done lately about women in the workforce and how we're still behind in pay and we're still behind in representation on executive boards and in large corporations so I think this is a big step in the right direction," Bell said.
Of the 40 percent of households with female breadwinners, 37 percent are married women who make more than their husbands and 63 percent are single mothers.
Evolving gender roles have also contributed to an increase in stay-at-home dads in addition to the traditional stay-at-home moms.
"We had to make a big decision of him staying at home with the kids and me doing extra overtime so I can pay the bills," Leonora Blanco, a hospital nurse in New York said.
Bell said that finding a passion and forming that into a career gives her a sense of fulfillment while setting an example for her children.
"I think it's an important life lesson to teach my kids, that you can have a passion about your work you can want to be the best that you can be at that. And that teaches them great lessons," she said.
New York mom and pharmacist Nancy Arbogast said she also hopes her daughter learns through example.
"It's helped my child, she knows she has to take care of herself, I would hope, and not depend on someone else," Arbogast said.
