USData
The data said so.
A free, public-data-only demographic data visualization tool. Drill down from a national view to individual Census Tracts, layering health, environmental, and economic data over a map — with an AI narrative layer that explains what the numbers mean in plain language.

Positioning
Why it exists
Tools like PolicyMap and Social Explorer already do this — but they're sales-led, paywalled, or built for professional researchers. USData is free, requires no account, and is built for anyone who wants to understand the place they live.
| PolicyMap | Social Explorer | USData | |
|---|---|---|---|
| Pricing | Sales-led, no free tier | Freemium (crippled) + paid | Genuinely free, no account |
| Depth (free tier) | Limited | County-level | Census Tract-level |
| Narrative framing | None | None | AI-generated, plain language |
| Data sources | Public + proprietary | Public only | Public only |
What it draws on
Census ACS, CDC PLACES, AHRQ social determinants of health data, and EPA environmental burden indicators — 61 indicators across four federal sources, combined into overlays you can compare side by side. Every value is attributed to its source; nothing is presented as more precise than the underlying data supports.
Built on public ground, by design
No proprietary data, no licensing risk, no paywall to work around. Same legal footing as the research-grade tools — available to anyone, not just institutions that can afford a seat license.
