CDC’s Social Vulnerability Index

ArcGIS Feature Layer

ATSDR’s Geospatial Research, Analysis & Services Program (GRASP) has created a tool to help emergency response planners and public health officials identify and map the communities that will most likely need support before, during, and after a hazardous event.

The CDC’s Social Vulnerability Index (SVI) uses US Census data to determine the social vulnerability of every county. The SVI ranks each county on 15 social factors, including poverty, lack of vehicle access, and crowded housing. It then groups them into four related themes: socioeconomic, housing composition and disability, minority status and language, and housing and transportation.
