The U.S. Census Bureau’s Community Resilience Estimates (CRE) for Heat provide experimental data to identify communities most vulnerable to extreme heat. This tool integrates social, economic, and environmental indicators to highlight areas at higher risk of heat-related impacts. By mapping heat vulnerability at the national, state, and local levels, the CRE for Heat supports public health planning, emergency response, and climate resilience strategies. It is a valuable resource for policymakers, researchers, and organizations working to address the growing health threats posed by rising temperatures and to prioritize support for populations with the greatest need for heat adaptation interventions.
