Dataset / methodology guide · Centers for Disease Control and Prevention
Read with context.
Inspect each indicator’s metadata before combining environmental conditions with health measures. Match the geography and time window and distinguish an exposure indicator from a health outcome. Use the official documentation to understand why a local value may be unavailable.
Coverage, uncertainty and time periods vary by indicator. Co-location on a map does not establish individual exposure or causation. This source guide is not an emergency alert or a medical assessment.
