Sources

Sources & provenance

Every number traces to an audited source file. Health outcomes come from CDC PLACES 2025 ZCTA estimates, ACS demographics, and ADI 2023 context in the complete parquet; the public PMTiles archive supplies the runtime ZCTA geometry used by the map.

Origin

Health prevalence estimates come from the CDC's PLACES project (model-based small-area estimates at the ZCTA level). ACS demographic variables are carried from the upstream ZIP atlas file, and ADI is from Neighborhood Atlas v4.0.1 area-aggregated to ZCTA. The geographic base is the Census TIGER/Line / ZCTA geography, served through the existing PMTiles archive.

Vintage. Health measures use CDC PLACES 2025. ADI uses Neighborhood Atlas 2023 v4.0.1. The app is a single cross-section; do not read it as a time series.

Coverage summary: 32,409 ZIP/ZCTA rows, 32,263 with current PMTiles geometry, 146 without geometry, and 105 without usable health measures after cleanup.

Join & coverage

The analytical source and the PMTiles geometry are matched on a zero-padded 5-character ZIP/ZCTA key. The PMTiles layer uses that key as its feature id, so the map can recolor by pushing static JSON values to geometry without rebuilding the source. Because all geometry-bearing rows in the updated parquet already exist in the PMTiles, this release does not require a new PMTiles file.

See Methods & limitations for how these numbers should and should not be read, or open the interactive atlas.
