Source Description
The County Health Rankings & Roadmaps (CHR&R) program is a collaboration between the Robert Wood Johnson Foundation and the University of Wisconsin Population Health Institute. CHR&R provides data, evidence, guidance, and examples in order to build awareness of the multiple factors that influence health and connect community leaders working to improve health and equity. The annual County Health Rankings measure vital health factors, including high school graduation rates, obesity, smoking, unemployment, access to healthy foods, the quality of air and water, income inequality, and teen births in nearly every U.S. county. The annual Rankings provide a revealing snapshot of how health is influenced by where we live, learn, work and play. CHR&R offers many pathways for self-directed and peer learning, web-based content, and virtual interactive forums that are designed to accelerate learning and action in communities to help build healthier communities and advance equity.

Methodology
Infant mortality data was acquired from the University of Wisconsin’s County Health Rankings (CHR). This measure represents the number of infant deaths (within 1 year) per 1,000 live births. CHR uses 2016-2022 seven-year averages from the National Vital Statistic System (NVSS) as the basis for their calculation. NVSS data are compiled from state death records and maintained by the Centers for Disease Control and Prevention.
