USAviz compiles public datasets into versioned snapshot releases. Each place page includes a "Data freshness" block showing the exact vintages used for that page.
If a dataset isn't included in the current release for a given page, you'll see it shown as "—" or "Not available yet".
Demographic and housing estimates (ACS 5-year).
Geographic boundaries (states, counties, ZCTAs, places, etc.).

Geographic relationship tables (e.g., ZCTA ↔ tract, ZCTA ↔ congressional district).
ZIP to ZCTA/CBSA/county crosswalk tables.
Model-based local health estimates (county/place/tract/ZCTA) derived from BRFSS and Census/ACS inputs. Some measures may be unavailable for specific places in a given release.
