How many single people are there in the U.S.?
Out Of Pocket TV · October 27, 2026
About 59 million men and 63 million women aged 18 to 80 in the U.S. aren’t married: just under half of all adults. But the balance between men and women swings a lot with age.
Unmarried adults by age
Share and number of U.S. adults in each age group who aren’t currently married, with the number of unmarried men for every 100 unmarried women:
| Age | Men | Women | Men per 100 women |
|---|---|---|---|
| 18–24 | 95% 14.8 million | 93% 14.0 million | 105 |
| 25–29 | 75% 8.37 million | 67% 7.40 million | 113 |
| 30–34 | 57% 6.72 million | 48% 5.63 million | 119 |
| 35–39 | 42% 4.86 million | 38% 4.42 million | 110 |
| 40–44 | 38% 4.26 million | 37% 4.07 million | 105 |
| 45–54 | 34% 6.73 million | 36% 7.36 million | 91 |
| 55–64 | 34% 6.67 million | 39% 8.20 million | 81 |
| 65–80 | 30% 7.04 million | 45% 11.9 million | 59 |
| All, 18–80 | 48% 59.4 million | 49% 63.0 million | 94 |
What stands out
- Under 25, almost everyone is unmarried. About 95% of men and 93% of women.
- Women marry earlier, so single men outnumber single women in their late twenties and thirties. At 30 to 34, 57% of men aren’t married against 48% of women: about 119 unmarried men for every 100 unmarried women.
- The middle is the most married. From the mid-thirties to the mid-sixties, only about a third to two-fifths of adults aren’t married.
- After 65 it flips hard. Women live longer and are more often widowed, so 45% of women 65 to 80 aren’t married against 30% of men. That’s about 59 unmarried men for every 100 unmarried women.
“Not married” isn’t the same as single
These are people who aren’t currently married: never married, divorced, widowed or separated. Plenty of them are dating, living with a partner or engaged. The Census Bureau counts marriage, not relationships, so the number of people who are truly available is smaller than this table, by an amount nobody measures well.
How these numbers are worked out
Counted from the individual records of the Census Bureau’s Current Population Survey, March 2025: about 108,000 adults in 56,000 households, weighted to represent the U.S. population. The calculator uses these same records for every single year of age, together with income and race, so “unmarried and 30” is a real count. See how the odds are calculated.
