Gender ratios by county and metro

Single men vs. single women in the 145 largest U.S. counties (100k+ residents aged 20-34). The ratio depends on what percentage of people you assume are in relationships - try changing it.

How is the ratio calculated?
1
Census headcount. The Census tells us how many men and women aged 20-34 live in each county.
2
Remove the taken ones. If 70% of women are in relationships, those women - and an equal number of men - leave the singles pool.
3
Divide. Remaining single men ÷ remaining single women = the ratio.
Below 1.0
Fewer single men than single women. Easier dating market for men, tougher for women.
Above 1.0
More single men than single women. Tougher for men, easier for women.
single men = men − (women × relationship%) single women = women × (1 − relationship%) ratio = single men ÷ single women

70% is a rough national average. You can change it in Filters & settings above.
