The population
Who you are asking
One synthetic profile per resident, built from public statistics and anonymized survey records. Every attribute below can define a population to ask, and every answer is broken down by them. Open an attribute to see its values and how the population splits across them. No profile describes a real person.
Who they are
From
US Census Bureau population estimates, 2025
Every state by single year of age, sex, race and Hispanic origin, reproduced cell by cell.
School and work
From
American Community Survey 2024, calibrated to published tables
Money and home
From
American Community Survey 2024, the person’s own household
Origin and service
From
American Community Survey 2024
Health and habits
From
National Health Interview Survey 2024 and the Behavioral Risk Factor Surveillance System 2024, by state
Drawn for every adult from survey distributions by sex, age, race and education, fitted to each state.
Civic life
From
Current Population Survey supplements: voting and registration (November 2024), civic engagement and volunteering (September 2023); the Cooperative Election Study 2024 for party, ideology and the presidential vote
Drawn from each supplement’s distributions by state, sex and age band; the voting rates match the Census Bureau’s published figures.
Elsewhere in the world
Every country and area by age and sex, with fewer attributes than the United States; the tree is shallower because the data is, and every answer says so.

What is not here yet
Cities and counties, households as groups of people with relationships, and your own customer lists. Attitudes are not attributes: they come from the simulation, checked against real surveys, and every answer says how far off its kind of question tends to be.
