Forty-seven percent of American adults under 50 who don’t have children now say they’re unlikely to ever have them, up sharply from 37% just six years earlier, according to Pew Research Center’s 2024 survey of more than 3,300 adults. The number one reason isn’t infertility, career ambition, or the economy. It’s simpler than that: 57% say they just don’t want children, full stop. No follow-up caveat required. That single data point undercuts a lot of the assumptions people carry into conversations about why someone in their 30s doesn’t have kids.
The reasons stack up differently depending on who’s answering. Among adults under 50, 44% point to wanting to focus on other priorities, career, hobbies, relationships, and 38% cite concerns about the state of the world. Money matters too: 36% say they can’t afford it, and 26% name climate change and environmental worries specifically. Only one in five say they simply don’t like children, which means the popular caricature of the childfree adult as kid-averse describes a small minority of the group.
The gender split that stands out
Women under 50 are considerably more likely than men to say they simply don’t want kids, 64% versus 50%, according to Pew. That gap shows up nationally in the raw numbers too. A separate analysis reported by Newsweek found 5.7 million more American women of prime childbearing age were childless in 2024 than demographic trends from prior decades would have predicted, and the U.S. has recorded 11.8 million fewer births over the past 17 years than expected. Between 2006 and 2024, the country gained 4 million more women aged 20 to 39, but 7 million fewer of them had given birth, a 45% jump in the childlessness rate for that age group. Researchers tracking the shift point to a familiar cluster of causes: the 2008 recession delayed a generation’s finances just as they were entering their prime childbearing years, the pandemic added a second disruption on top of the first, and the cost of child care in many metro areas now rivals a mortgage payment.
Adults 50 and older who never had children tell a different story about why. Only 31% in that group say they simply didn’t want kids, well below the 57% figure for younger adults. Instead, 33% say they never found the right partner, and 21% wanted to prioritize other things in life. It’s a reminder that “childfree” and “childless” aren’t always the same experience, one implies a choice made and held; the other sometimes describes a life that unfolded around an absence nobody planned.
What the tradeoff actually buys
Pew’s respondents are candid about the upside. Among adults under 50 without kids, 80% say not having children gives them more time for hobbies and interests, 79% say it’s easier to afford the things they want, and 75% say it’s easier to save for the future. Those numbers run a bit lower for adults 50 and up, 57% cite more time, 61% cite easier spending, but the direction holds across both groups.
The tradeoff isn’t free of worry, though. Among adults 50 and older without children, 35% say they frequently worry about having enough money as they age, 26% worry about who will take care of them, and 19% worry about loneliness. Pew also found that childless older women earn higher median wages than mothers of the same age, a gap that likely reflects both the career continuity nonparents maintain and the wage penalty that still follows mothers through their working lives. Demographically, adults 50-plus without children are less likely to have ever married and more likely, especially among women, to hold a bachelor’s degree. Education level also shapes which reasons people give: adults with less formal schooling are somewhat more likely to cite affordability as a barrier, while those with a bachelor’s degree or higher more often point to career priorities or simply not wanting the role, suggesting the “choice” and “circumstance” categories overlap more than the survey’s own tidy percentages might suggest.
None of this describes a monolith. Some of these adults actively chose a life without kids in their 20s and never looked back. Others spent their 30s and 40s waiting for circumstances, a partner, stable finances, a world that felt less precarious, that never quite arrived. What the data makes clear is that the decision, when it is one, rarely comes down to disliking children. It comes down to what a life without them makes room for, and increasingly, more adults are deciding that room is worth keeping.
