Pew: 52% of heterosexual parents now have both working full-time under 18

If you thought the two-income household was “the trend,” Pew’s new numbers make it “the rule.” For the first time in U.S. history, the majority of heterosexual households have two full-time, working parents. And in the specific segment that matters for day-to-day childcare and budgeting, Pew reports that both parents in more than half, 52%, of heterosexual couples with kids under 18 hold full-time jobs.

That headline statistic is the story underneath the story: it is not just that more people work. It is that the stay-at-home parent is declining, while expectations at home are not. Pew found that about a fourth of families are made up of a dad who works full-time and a mom who is unemployed. At the other end, only 6% of moms work full-time while their male partner isn't employed or works part-time. And Pew also found that another 14% of working parents aren’t married or don’t live with a partner.

The practical implication is that “work-life balance” is no longer a perk conversation. It is becoming a structural constraint. When more households depend on two full-time incomes, any disruption in one paycheck reverberates through childcare, housing, and transportation. Pew ties this shift directly to mounting affordability stress. Homeownership, stable employment, and even feeding kids can feel increasingly unattainable as high inflation and higher interest rates consume a larger share of household income. Pew also reports that nearly a third of Americans say high living costs are their main financial problem, up sharply from 3% in 2020.

What does that mean in dollar terms for families? Pew points to LendingTree research showing that raising a child costs more than $300,000 over the first 18 years, compared with $165,630 about 25 years ago. It is also why affordability is getting measured in childcare terms. Pew cites that a two-child household must earn more than $400,000 a year for childcare to be considered affordable by federal guidelines. The squeeze then shows up in how people describe their finances: half of Americans say they have just enough money to maintain their standard of living, and nearly a fifth say they’re falling behind.

Now add another pressure: parents are expected to spend more time with their children. Pew found that more than half of parents who work full-time struggle to balance work and family responsibilities. The “two full-time incomes” reality does not automatically reduce the care burden. Instead, the burden of child and household care still falls overwhelmingly on women, even when her earnings surpass his. Pew’s findings echo Wharton economist Corinne Low, who previously told Fortune that working moms today are spending more time with their kids than stay-at-home moms when she was a child. Even with that, Low also described the uneven division at home: when a wife outearns her husband, she still does almost twice as much cooking and cleaning as her partner. Pew reinforces the imbalance with a caregiving statistic from the National Partnership for Women & Families: nearly two-thirds of caregiving is done by women, and if American women were paid for all their unpaid labor, it would be worth $683 billion.

The distribution of who is working full-time also matters for employers, boards, and policymakers because it is not uniform across groups. Pew reports that six in 10 partnered Black mothers work full-time, down from 64% in 2000. Meanwhile, the share of working Asian and white moms increased over time: 54% of Asian moms and 52% of white moms work full-time. Pew adds that about 45% of Asian and white moms worked full-time 25 years ago. Hispanic families look different: Pew says the share of full-time, double-income families has held steady over the last 25 years at about 44%. At the same time, about one third of Hispanic mothers aren’t employed, the highest rate of unemployment across racial groups.

Education is another divider. Pew reports that about seven in 10 partnered mothers with an advanced degree work full-time. Over half of moms with a bachelor’s degree work full-time, compared to 43% of moms with less education. For corporate decision-makers, these differences show up as uneven labor supply pressure, uneven turnover risk, and uneven reliance on benefits that can materially affect household stability.

Finally, Pew finds that families where both parents work at least part-time see more financial benefits than families where just the father works. And importantly, Pew reports that all parents surveyed said their family’s work arrangement has not had a positive or negative effect on their career advancement. That particular detail matters for boards and executives because it suggests the labor reallocation is not being chosen for “career optimization.” It is being adopted for survival, while the caregiving expectations remain.

So the second-order stakes for leaders are blunt: when 52% of couples with kids under 18 run on two full-time incomes, the household economy becomes more sensitive to payroll shocks, scheduling volatility, and childcare affordability. That sensitivity can change the demand for flexible work, benefits design, and retention strategies, even if workers themselves do not report a direct effect on career advancement. The affordability crisis is not staying in the living room. It is moving through labor markets, compensation models, and how companies plan for a workforce that is constantly balancing the math of home with the schedule of work.
