The 500 Cities project was replaced by the PLACES Project in 2020, an extension of the project, which continues to allow health departments and jurisdictions to understand the distribution and burden of health-related outcomes in their communities. See bottom of the PLACES Project page for the note for data users.
The 500 Cities project was a collaboration between CDC, the Robert Wood Johnson Foundation, and the CDC Foundation. The purpose of the 500 Cities Project was to provide city- and census tract-level small area estimates for chronic disease risk factors, health outcomes, and clinical preventive service use for the largest 500 cities in the United States. These small area estimates allow cities and local health departments to better understand the burden and geographic distribution of health-related variables in their jurisdictions, and assist them in planning public health interventions.
