What the St. Louis data shows
This report makes the map's underlying coverage, summary statistics, methodology and limitations readable without requiring JavaScript. Values describe geographic areas, not individual people or properties.
Metro snapshot

How to interpret the map
Choose a metric, then hover or select a census tract to see its profile. Census figures are multi-year survey estimates and carry margins of error. Housing-market figures are ZIP-level Redfin aggregates associated with tracts for geographic comparison; they are not individual transactions. School points show reported performance and locations, not attendance boundaries. Crime and local-government coverage varies because agencies publish different datasets.
The composite “Neighborhood strengths” and “Hardship indicators” layers summarize multiple housing, education, income and safety measures. Race and ethnicity are available as separate descriptive Census layers and are not inputs to those composite scores. Read the full formulas and review standards on the methodology page.
Coverage and update notes
This build exposes 82 mapped measures and cites 9 primary or established data providers. It was generated on 2026-08-03. A metro is published only after geometry, population, housing, market, health and hazard coverage pass the site's documented quality gate; unavailable local layers are identified instead of being displayed as zero.
