Method
No spreadsheet required. We start with the whole adult room, then ask: after your list, how many people are still standing?
The one-sentence version
The lime percent is the share of adult men or women who match all of your filters at the same time — using official US numbers on the US side and official Canadian numbers on the Canada side.
1
We begin with all adults 18+ of the gender you picked — men or women — in the United States, Canada, or both. That is the full room.
2
Age, height, income, ancestry, and the rest each keep only the people who match. The lime bars on The Odds are that slice: “kept 16%” means 84% just left the room.
3
The big lime number is what is left after every filter, one after another. If age keeps 1 in 6 and height keeps 1 in 2 of those, you now have about 1 in 12.
4
That leftover share is multiplied by the real adult population. So 0.18% of US men is still hundreds of thousands of people — rare as a percent, not “nobody.”
Imagine 1,000 adult men. Age 25–34 keeps about 160. “At least 5′9″” keeps about half of those, so 88. A $75,000 income keeps about 1 in 5 of those, so roughly 17 people — about 1.7%. That is the same math The Odds runs, just with census-sized rooms instead of 1,000.
Quick check we use on ourselves: about 15% of US adult men are 6′0″ or taller. Right now the engine says 14.7%. If that ever drifts, the height math is wrong.
United States. Census ACS 2024 for how many adults, marriage, education. NHANES 2021–23 for height. CDC for obesity. ACS race/ethnicity (White here means non-Hispanic White).
Canada. Statistics Canada population for 1 July 2025. Canadian Health Measures Survey for height and obesity. 2021 Census for marriage and common-law, visible-minority groups, and education.
