Conduent Healthy Communities Institute



  • The PLACES Project is an 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.
  • This project represents a first-of-its-kind data analysis to release information for all US counties, places, census tracts, and ZCTA-level data and uses small area estimation methods to obtain 27 chronic disease measures for the entire United States.
  • The data from this project complements existing surveillance data necessary as a method to more fully understand the health issues affecting the residents of local areas of all sizes and regardless of urban or rural status.


  • County: There are 3,142 counties within 50 states and District of Columbia (DC), including 9 county and city consolidated cities.
  • Place: 28,484 of 29,321 Places or Census Designated Places (CDP) with a population of 50 or more from Census Tiger 2019 Places and CDPs based on the Census 2010 population count.
  • Census tract: 72,337 of 73,057 census tracts in the 50 states and Washington, DC that have a Census 2010 population of 50 or more people. Compared with the original 500 Cities Project in which estimates were made only for the part of tracts within cities, this project will provide the estimates for the entire census tract regardless of city boundaries.
  • ZCTA: 32,409 of 32,989 ZCTAs in the 50 states and Washington, DC with Census 2010 population of 50 or more people.
