Expansion of the original 500 Cities Project that began in 2015. The original project was launched by the Centers for Disease Control and Prevention (CDC) in partnership with the Robert Wood Johnson Foundation (RWJF) and CDC Foundation. In 2018, this partnership was extended through 2020. In 2020, the project expanded to provide small area estimates (SAE) for counties, places, census tracts, and ZIP Code Tabulation Areas (ZCTA) across the entire United States. Reflects innovations in generating valid small area estimates for population health and provides data uniformly across the urban-rural spectrum. 2019 and 2024 are also available on DataLuomos.
