How to read the table
Column: Men / woman
0.90 means 90 men for every 100 women aged 20–34. At 1.00, the counts are equal; 1.10 means 110 men per 100 women.
Column: Modeled singles
67/100 means about 67 single men per 100 single women. Equal numbers would be 100/100.
The default scenario pairs 70% of women with men in the same area and age group, then subtracts those couples from the population counts. The Census data used here doesn't count singles. Adjust the percentage under Filters.
| Men | Women | Ratio | |
|---|---|---|---|
| Everyone | 90 | 100 | 0.90 |
| In couples 70% of women | −70 | −70 | |
| Still single | 20 | 30 | 0.67 |
After subtracting couples, the ratio falls from 0.90 to 0.67: 26% fewer men per woman among singles.
Assume each partnered woman has a male partner in the same area and age group. Choose 0–90%. At 0%, both columns describe the same ratio. Higher percentages move an uneven singles ratio farther from 100/100.
Only counties with more than 50,000 residents aged 20–34 are included. Raise the minimum to show larger counties.
On small screens, columns that don't fit appear below each area's name.
