California's Divorce Rate Is One of the Lowest in the Country. San Francisco Is Where That Number Stops Meaning Anything.

Let's start with the number that makes California look enviable.

California's divorce rate sits at roughly 8.9% of the adult population, down from about 9.8% in 2014, placing it among the states with the lowest per-capita divorce rates in the country, according to divorce-statistics analysis of Census data. It's the kind of number that would normally suggest a state getting steadily better at marriage.

San Francisco is the city inside that state where the number stops describing anything useful, because San Francisco's low divorce rate isn't downstream of stable marriages. It's downstream of a historically low number of marriages happening at all.

An independent analysis of Census data covering San Francisco, Minneapolis, and Dallas found that less than 40% of San Franciscans are married by age 32, compared to roughly half of Minneapolis residents at the same age — a 20-percentage-point gap that peaks around age 29. Among the 183 U.S. counties with populations over 400,000, San Francisco ranks 9th-least-likely for 30-to-35-year-olds to be married, behind only a handful of counties including those containing Baltimore and Philadelphia. The same analysis found just 18% of San Franciscans aged 30 to 35 have children — the lowest rate of any major county in the country.

This lines up with a national pattern that's already reshaping how demographers talk about marriage. A quarter of 40-year-olds in the United States have never married, according to Pew Research Center analysis of Census data — the highest share since the data was first tracked in 1900, up from just 6% in 1980. Men are more likely than women to be unmarried by 40 nationally, 28% versus 22%. San Francisco appears to be running meaningfully ahead of even that elevated national curve, to the point that Census-based estimates comparing the city to New York and the national average circulated widely in tech circles in early 2026, putting San Francisco's rate of men reaching 40 without marrying at roughly double the national figure.

The reason isn't a mystery to anyone who's dated in the city. San Francisco's tech industry runs on a specific cultural premise — that your twenties and often your thirties belong to your career, your equity, and your next raise, in a way few other industries formalize as explicitly. Long hours, founder culture, and a professional environment where prioritizing a relationship over a company is treated as a notable, sometimes newsworthy decision, are structural features of the city's dominant industry, not individual failures of commitment. Add San Francisco's standing as one of the most expensive cities in the world to raise a family in, and both marriage and parenthood get pushed later — for some, indefinitely — not because people stopped wanting them, but because the two industries defining the city's culture and cost of living both quietly reward delay.

This reframes what California's comparatively low divorce rate is actually measuring in a city like San Francisco. It isn't that San Francisco couples are exceptionally good at making marriage work. It's that an unusually large share of San Franciscans, particularly men in their thirties and forties, aren't reaching marriage on anything close to the national timeline — which mechanically keeps the divorce number low simply because there are fewer marriages in the population to end. The same distortion that makes a falling U.S. divorce rate misleading nationally is present here in a more extreme, industry-specific form.

None of this means San Francisco singles have given up on partnering off, and the tech entrepreneur whose viral career-versus-family post kicked off renewed discussion of these numbers in 2026 wasn't alone in describing a shift back toward prioritizing relationships once the costs of delay became visible. It means the city's low divorce rate was never a signal that dating and marriage are working well here. It's a signal that an entire cohort of San Franciscans is running years behind the rest of the country on reaching the stage where a divorce rate would even apply to them — not because they don't want what comes next, but because the city's two defining forces, its industry and its cost of living, have made "later" the path of least resistance for longer than almost anywhere else in America.
