Health Impact Assessment Resources

The CDC's Health Impact Assessment Resources page provides guidance on using environmental and public health data to support Health Impact Assessments (HIAs) of proposed plans, policies, programmes, and projects. It highlights how the CDC's Environmental Public Health Tracking Network can be used throughout the HIA process—from community engagement and scoping to assessment, monitoring, and evaluation—by providing nationally consistent data on air quality, health outcomes, demographics, socioeconomic conditions, and environmental hazards.

The resource includes practical guidance, case studies, pathway diagrams, and data guides for conducting HIAs in sectors such as transportation, land use, and climate change. It also explains how users can combine Tracking Network data with GIS tools, state and local datasets, and analytical models such as BenMAP to assess health impacts and inform decision-making. The resource is intended for public health practitioners, policymakers, planners, researchers, and other stakeholders seeking to integrate health considerations into environmental and development policies.
