Data Sources & Methodology

All indicators are compiled from public federal and academic datasets into a single county-level table (FIPS-keyed, 3,144 counties):

• CDC PLACES 2024 (model-based small-area health estimates)
• County Health Rankings 2024
• NCI State Cancer Profiles
• USDA Economic Research Service (ERS) and USDA Food Environment Atlas
• US Census population data

The map geometry uses the US Atlas counties TopoJSON (10m resolution). Values shown are the most recent available in each source at compile time; each metric panel in the app labels its source and year.
