500 Cities: Local Data for Better Health

500 Cities Project. Data on 27 chronic disease measures, health outcomes, and clinical preventive service use for the 500 largest U.S. cities is available on-line thanks to a collaboration among the CDC, the CDC Foundation and the Robert Wood Johnson Foundation. An interactive website provides the ability to retrieve, visualize, and explore uniformly-defined city and census tract-level data. The data are derived from small area estimates.
