How many single people have no kids?
Out Of Pocket TV · October 27, 2026
“Single, no kids” is one of the most common things people ask for, and in your twenties it barely narrows anything down. By the early thirties it rules out most people: about 24% of women and 40% of men aged 30 to 34 are both unmarried and have never had a child.
By age
Share of U.S. adults who have never had a child, and who are both not married and have never had a child:
| Age | No kids: men | No kids: women | Not married, no kids: men | Not married, no kids: women |
|---|---|---|---|---|
| 18–24 | 91% | 84% | 89% 13.8 million | 81% 12.2 million |
| 25–29 | 72% | 70% | 62% 6.90 million | 54% 5.99 million |
| 30–34 | 51% | 34% | 40% 4.68 million | 24% 2.82 million |
| 35–39 | 35% | 29% | 25% 2.87 million | 17% 1.95 million |
| 40–44 | 28% | 18% | 19% 2.16 million | 11% 1.26 million |
| 45–54 | 27% | 16% | 16% 3.25 million | 9.1% 1.87 million |
| 55–64 | 24% | 15% | 14% 2.83 million | 8.1% 1.72 million |
| 65–80 | 18% | 13% | 9.5% 2.18 million | 7.4% 1.94 million |
What stands out
- The big drop is between 25 and 35. Unmarried and childless goes from 62% of men aged 25 to 29 to 25% at 35 to 39. For women it goes from 54% to 17%.
- Women have children earlier than men, so at every age a smaller share of women than men have never had a child.
- In the early forties, it’s about 1 in 5 men and 1 in 9 women. That’s still millions of people, but it’s a standard that does a lot of work.
- “No kids” and “not married” aren’t independent. People who have never married are much less likely to have children, so the calculator counts the two together for each age rather than multiplying them.
How these numbers are worked out
“No kids” means the person has never had a child, by age and by whether they have ever married. The women’s figures come from the Census Bureau’s Current Population Survey (June 2024). The men’s come from the Census Bureau’s Survey of Income and Program Participation (2014), the most recent it has published on men’s fertility, so they are the older of the two. Marital status is from the Current Population Survey, March 2025. How the odds are calculated has the details.
