Where the numbers come from
- Age, income, race and relationship status come from the Census Bureau's 2024 American Community Survey microdata: 2.6 million survey records of adults aged 18 to 80, weighted to represent 255 million people. Everyone living in the US is included, including people in college dorms, military barracks and nursing homes.
- Height comes from the CDC's National Health and Nutrition Examination Survey (2017–2020 and 2021–2023), where about 15,000 adults were measured without shoes. We model height by sex, race and age group with a bell curve, which lands close to the measured share of men 6′0″ or taller (15.3% modeled vs 14.8% measured). Height is assumed to be unrelated to income and relationship status within each group.
- Build also comes from NHANES. Not obese means a body mass index under 30, from measured height and weight (2017–2023 exams, leaving out pregnant women). Has a six pack counts as body fat of 15% or less for men and 22% or less for women on a whole-body DXA scan (2011–2018 exams), the top of the ranges where abs usually show. Only about 170 men and 40 women scanned were that lean, so six-pack shares vary by sex and age group but not race, and people 60 and over, who weren't scanned, get the share for ages 50 to 59. Build is assumed to be unrelated to income, home, relationship status and height within each group.
- Owns a $1 million home counts people in a home their household owns, with or without a mortgage, that the owner says would sell for $1,000,000 or more. Only the householder and their husband or wife count, so renters, grown children living in a parent's home and an owner's unmarried partner don't.
- Business class and luxury shopping counts as personal income of $250,000 or more. That budget covers about two business-class round trips to Europe (around $12,000) and about $12,000 of luxury shopping a year, kept to roughly 10% of pre-tax income.
- Income is total personal income before tax: wages, self-employment, investments, retirement and benefits, in 2024 dollars. Household income and wealth aren't counted.
- Race or ethnicity: anyone Hispanic or Latino counts as Hispanic or Latino. The other groups are non-Hispanic people who report one race. “Another race or multiracial” covers American Indian and Alaska Native, Native Hawaiian and Pacific Islander, some other race, and two or more races.
- Relationship status: separated people count as married. Unmarried couples, including those living together, count as not married, so the real number of available people is lower.
- Small samples: very narrow lists rest on few survey responses, so the calculator warns you when a count is shaky.
