Female Delusion Calculator estimates what share of US adults match a set of dating standards. This page explains where each number comes from, how the result is calculated, and where the method falls short. If you haven’t tried it yet, the calculator takes about 30 seconds.
The basic calculation
Every filter you choose is converted into the fraction of US adults who meet it. The fractions are multiplied together to get a combined share. That share is then applied to the US adult population of the sex you selected to give a headcount, and converted into a score from 1 to 10.
Example: if about 16% of men are 6’0″ or taller and about 37% have a bachelor’s degree, the calculator multiplies 0.16 by 0.37 and gets roughly 6% of men who meet both filters.
Data sources
| Filter | Source and details |
|---|---|
| Height and BMI | CDC National Center for Health Statistics, Anthropometric Reference Data, August 2021 to August 2023. Measured values for adults 20 and older, using the published percentile tables (5th to 95th), with values between them interpolated. |
| Education | US Census Bureau, Educational Attainment in the United States: 2024, adults 25 and older. Graduate-degree shares are calculated from the published Census counts. |
| Single status | US Census Bureau, America’s Families and Living Arrangements. About half of adults live with a spouse and about 8% with an unmarried partner. |
| Income | Rounded estimates modeled on the Census CPS personal income tables. These cover all adults, including people who are not working. |
| Age and population | Rounded estimates based on Census population figures. |
Limitations
Filters are treated as independent. In reality some traits are correlated, for example age and income, so a combined result can be off in either direction.
Education data is for adults 25 and older, and body measurements are for adults 20 and older. They are applied across the age range you choose.
The data covers the United States only. It doesn’t measure personality, attraction, values or compatibility, which matter more in real relationships than any statistic.
Some inputs are rounded estimates, as noted in the table above. The score is a rough guide, not a precise measurement.
How the score works
The score reflects how small the matching share is: 1 to 3 means more than about 5% of people match, 4 to 5 means roughly 1% to 5%, 6 to 7 means roughly 0.1% to 1%, and 8 to 10 means under about 0.1%.
Updates and corrections
We review the data when the CDC or Census Bureau publishes new releases. The data was last updated in October 2026. If you spot an error, please contact us and include a source if you have one.
