50-State Single Adult Demographics & Gender Ratio Census Atlas
Searchable state-by-state directory analyzing adult unmarried populations, single sex ratios, and metropolitan dating pool distributions from 2024 U.S. Census data.
National Overview: U.S. Single Population Geography
According to the 2024 U.S. Census Bureau CPS ASEC, 50.4% of American adults are unmarried (130.4 million people), with significant geographic imbalances ranging from 1.13 single men per woman in North Dakota to 0.86 single men per woman in Washington, D.C.
Relationship availability in the United States is deeply stratified by geographic division. While nationwide adult sex ratios remain near parity (0.96 men per woman due to female longevity in older cohorts), the active dating pool (unmarried adults aged 18 to 49) exhibits pronounced local divergence driven by industrial employment, migration patterns, and educational sorting.
Resource-extraction and tech-concentrated states in the Mountain West and northern plains (such as Alaska at 1.11, Wyoming at 1.12, and North Dakota at 1.13) feature substantial male surpluses. Conversely, metropolitan hubs and southern service economies (such as Washington D.C. at 0.86, Mississippi at 0.88, and Louisiana at 0.89) exhibit marked female surpluses among unmarried adults.

Understanding Singles Ratio Dynamics: Why Geography Dictates Dating Probabilities
When using demographic calculators like the Female Partner Calculator or the Male Partner Reality Check, nationwide probability outputs provide a critical macro baseline. However, individual romantic outcomes are heavily mediated by local municipal and state-level sex ratios.
In urban sociology and demographic economics, this phenomenon is formalized as the marriage market squeeze. In areas where one gender outnumbers the other by even 5% to 10% in the unmarried cohort, competition and selectivity shift dramatically. For instance, in Washington D.C., where single women outnumber single men 245,000 to 210,000 (ratio 0.86), women encounter higher selectivity barriers, while single men encounter broader partner availability.
Conversely, in states like Alaska (ratio 1.11) and Colorado (ratio 1.06), the surplus of unmarried men significantly expands the availability of male candidates for women, but tightens competition for single men seeking partners.
Frequently Asked Demographic Questions: 50-State Singles Data
01Which US state has the highest ratio of single men to single women?
North Dakota features the highest ratio of unmarried men to unmarried women at 1.13 men per woman, followed closely by Wyoming (1.12) and Alaska (1.11), largely driven by energy, agriculture, and industrial workforce migration.
02Which US metropolitan area or region has the highest surplus of single women?
Washington, D.C. has the highest surplus of single women in the nation, with a sex ratio of 0.86 single men per woman (53.8% unmarried women vs 46.2% unmarried men), followed by Mississippi (0.88) and Louisiana (0.89).
03How does state geography impact individual dating calculator probabilities?
Individual partner probabilities calculated on our national models reflect the baseline U.S. average. In states with male surpluses (>1.08), single women experience an expanded eligible candidate pool, whereas in states with female surpluses (<0.92), single men experience an expanded candidate pool.
