synthePopulation & households
National censuses, population registers, official estimates, published tables, and microdata provide demographic and household constraints.
A model is only as useful
as the evidence behind it.
Different sources answer different questions. Population counts, household relationships, activities, geography, psychographics, and observed responses each contribute a different part of the picture.
PUBLIC REFERENCE POINTS
From source to context.
Selected source families and public reference links. The specific datasets, reference years, access terms, and use in a model vary by country and release.
Demographic reference frames
Population estimates provide a reference where censuses are older or where national source coverage differs. An estimate and a census are different evidence types.
Activities & time use
Time-use surveys describe how people allocate time to work, family, travel, social life, and other activities. They help constrain modeled routines.
Places & geographic context
Building footprints, roads, services, and destinations connect population structure to places. A building footprint is not a count of households or occupied homes.
Psychographics & behavioral research
Academic studies and published survey findings inform assumptions about traits, interests, and responses. Local news and social signals can add context, but do not replace representative statistical evidence.
Study-specific papers, measures, sampling context, and model assumptions need to be assessed together. This page is not a complete release bibliography.
Human evidence & validation
Human surveys and observed outcomes can provide benchmarks for calibration and testing where available and permitted. Validation is tied to a study, population, place, and time.
Fitting demographic distributions does not by itself validate opinions, behavior, or responses to a new scenario.
Keep the distinctions visible. Observed statistics, research-based priors, modeled attributes, and validation outcomes are different evidence classes. Source availability alone does not establish representativeness or predictive accuracy.
THE ECOSYSTEM / TEXT OVERVIEW
What sits behind a study?
Read from the application layer down to its evidence foundation, or explore the same relationships in 3D.
Research questions & scenarios
Define a question, explore population segments, compare scenarios, and interpret results within their validated scope.
A population-grounded study workflow
Select a population, prepare questionnaires and scenarios, examine responses, compare outputs, and review study results.
Responses and the evidence to assess them
Behavioral models link profiles to stimuli and circumstances. Validation examines fit and performance against appropriate benchmarks.
Linked lives
Family structure, likely workplaces and schools, summer homes, activities, media interests, and psychographics add context to demographic profiles.
Time and scope remain explicit
Versioned population releases preserve reference periods and geographic scope, including Ukraine’s national quarterly snapshots.
People, households, and geography
Country-specific population models and data frames connect individuals and family members to places. Data depth differs across the 73 listed countries and territories.
A traceable evidence foundation
Official statistics, census microdata, geography, time-use surveys, research, and validation evidence contribute distinct constraints and checks.
Ukraine’s national figures describe modeled residents of government-controlled territory. The 3.858M internally displaced people are included in the latest 29.0M resident total. See snapshot details.
