DC Has the Highest Marriage Rate in America. The Chamber of Commerce Still Calls It the Loneliest City in the Country
Let's start with the number that looks like the best story in this entire series.
Washington, D.C. posted the highest marriage rate of any state or state-equivalent in the country, at 24.4 marriages per 1,000 population, according to a 2024 Census Bureau analysis of national marriage and divorce trends — well ahead of runners-up Colorado and Nebraska. D.C. also posts one of the lowest divorce rates among married women nationally, per the same category of state-level CDC data. Read together, those numbers describe a place where people marry more, and more successfully, than almost anywhere else in America.
Read against a third number, they stop making sense. The Greater Washington DC Chamber of Commerce has specifically flagged the city as one of the loneliest in the country, despite Census data showing 69.3% of D.C. residents aged 20 and older are single, and 48.6% of households consist of one person living alone, according to demographic research on the city's dating market. A city can't simultaneously lead the nation in marriage and be singled out for loneliness by its own chamber of commerce unless those two numbers are describing different populations — and D.C.'s underlying gender data explains exactly how that happens.
D.C. has one of the most lopsided ratios of unmarried men to unmarried women of any state in the country. A U.S. Census Bureau analysis specifically built to measure "marriage market" odds found just 80 unmarried men for every 100 unmarried women in the District — among the lowest ratios in the nation, well below the roughly 90-to-100 national average for unmarried adults, and dramatically below states like Alaska, which has 117 unmarried men per 100 women. The Census Bureau's own framing of why this matters is direct: people select partners from the pool of eligible candidates actually available to them, and a market this skewed structurally limits the odds for the side with fewer options — in D.C.'s case, women.
This is where D.C.'s headline marriage rate reveals what it's actually measuring. A marriage rate counts marriages against total population in a given year — it's a flow statistic, not a snapshot of who's stuck. D.C. has an unusually large, unusually young, and unusually high-turnover population of arriving professionals, drawn by government, policy, law, and the nonprofit sector that clusters around federal institutions. Some meaningful share of that population marries and then leaves the District for the suburbs or another city entirely, which keeps the flow of marriages high without doing anything to shrink the pool of new, mostly female singles arriving to replace them. The marriage rate captures the successful exits. It says nothing about the people left circulating in a dating market that keeps refilling on one side faster than the other.
The industries drawing people to D.C. compound the effect rather than offsetting it. Government, policy, law, and non-profit work in the District skew toward fields with historically strong representation of college-educated women, layering an occupational pattern on top of an already unbalanced gender ratio. It's a version of the same college-education mismatch driving dating difficulty in cities like Boston and Atlanta elsewhere in this series, except in D.C. it's sorted by industry and federal-city gravity rather than by university enrollment alone.
Put these pieces together and D.C.'s two headline statistics stop contradicting each other and start telling one continuous story. The highest marriage rate in the country reflects a population efficient at marrying once a match is found — genuinely good news for the people it applies to. The lowest unmarried-men-to-women ratio in the country reflects a much larger population still searching, disproportionately women, in a market that keeps adding singles faster than it pairs them off. Both are true. The chamber of commerce's "loneliest city" label isn't a contradiction of the marriage-rate headline. It's a description of everyone the marriage-rate headline leaves out.
None of this means D.C. singles have given up — the sheer size of the dating-age population actively looking, cited in the same research calling the city lonely, says the opposite. It means the number most likely to get quoted about D.C.'s relationships is measuring the exits, not the odds. For the majority of singles still in the market, particularly women, the odds the Census Bureau actually measured — 80 men for every 100 women — are the number that describes their experience of the city. The marriage rate describes everyone else's.
