Solutions

One population, asked in many ways

Every solution below runs on the same calibrated population and the same question engine. What differs is who asks, what they ask, and which geography they need. Every answer carries its interval, who said what, and why.

By industry

Market and opinion research
Insights teams, agencies and pollsters

Ask: How a defined population would answer a survey item, before the field work is commissioned; which segments differ and by how much.

Get: The share choosing each option with its interval, breakdowns by sex, age, education, employment and state, the reasons people give, and a check of the question wording before it costs anything.

Consumer brands and product teams
Product managers, pricing and category teams

Ask: Willingness to pay, choice between alternatives, reactions to a concept, by the customers you actually have.

Get: A number with its interval and the distribution behind it, the split by who your customers are, and what people say when they explain the choice.

Media and advertising
Planners, strategists and audience teams

Ask: The size and shape of an audience, and how it would respond to a message, in a state or a country.

Get: Audience counts from a population calibrated to official statistics, the response to a message with its interval, and the breakdown by age, education and place.

Public policy and government
Ministries, agencies, think tanks and NGOs

Ask: How a policy lands with the people it affects, by region and by group, and how large each affected group is.

Get: Counts and shares from the calibrated population, support and opposition with intervals, the difference between two populations, and the reasons on each side.

Academic and social research
Researchers, survey methodologists and students

Ask: Pilot a questionnaire, explore expected effect sizes, or draw a representative synthetic sample with known provenance.

Get: A population you can inspect before you run, every attribute with its source, and simulated answers with a measured distance from real survey answers for their kind of question; a trial runs your instrument with us.

AI and simulation builders
Teams building agents, digital twins and simulations

Ask: A population to sample agents from that matches official statistics instead of a prompt, and a way to check how close a simulation is to real people.

Get: A declared population to sample agents from, ninety attributes each with its source, and a calibration record to compare your own simulation against; a demo shows a run end to end.

Health and public health
Public health teams, payers, providers and health-product marketers

Ask: How people with a condition (diabetes, high blood pressure, asthma), smokers, drinkers or people in poor health would answer, by state and by group; and how large those groups are.

Get: Counts and shares of health populations from a layer calibrated to national health surveys and fitted to each state, their answers with intervals and breakdowns, and the reasons they give.

By geography

What the population carries today, and what arrives next, so you know what an answer rests on before you ask.

United States

Today: 51 states, every resident by age, sex, race and origin, with education, occupation, industry, income by source, marital status, citizenship, birthplace, language, veteran status, disability and health insurance by type, commute, school enrollment, and the household they live in (size, composition, tenure, income, vehicles, internet), matched to Census and American Community Survey data. The deepest population and the first place every new attribute lands; and health and behaviour on every adult (smoking, drinking, self-rated health, anxiety and depression, high blood pressure, diabetes, asthma, weight, sleep) from the National Health Interview Survey.

Next: Counties, then household structure: the people someone lives with as synthetic persons of their own.

Rest of the world

Today: 237 countries and areas by age and sex from the UN's 2025 estimates. Ask about any country today.

Next: Education levels for every country, then each country's own census: regions, households, income.

Europe

Today: Every European country by age and sex, plus employment status; the same questions work, with the same intervals.

Next: Regions and socioeconomic detail from Eurostat and the national offices (ONS, INSEE, Destatis, INE), the first non-US geography to reach US depth.

The accuracy benchmark

Simulated answers are only worth what they cost you if they are close to real ones. We are building a public benchmark: real people, paid, asked the same questions as every simulation provider, including ours; the raw results and the scoring published each wave. Until the first wave is out, every answer on this site says plainly whether its question type has been checked against a real survey.
