01A fair comparison needs the same filters
If one side is filtered by income and height while the other is filtered by age alone, the result says more about the setup than either gender. The calculator applies every selected filter to both groups simultaneously.
02Rarer does not mean more valuable
The smaller pool is only less common under the selected demographic rules. A headcount cannot measure kindness, emotional availability, relationship skills, or compatibility.
03What can change the comparison?
Age, personal income, height, marital status, BMI, and location can shift the result sharply. State pages change the demographic base; physical-trait estimates remain national because the public health tables are not state-specific.
