Recently the 500 Cities project, a collaboration between the U.S. Centers for Disease Control and Prevention (CDC) and the Robert Wood Johnson Foundation, released small-area estimates of health outcomes, risk factors, and healthcare usage for the 500 largest cities in the U.S. While health measures are often reported at the state level, the 500 Cities project seeks to equip local health stakeholders with more granular estimates of community health data, thereby informing important policy, planning, and programmatic decision-making.
