CDC/ATSDR Social Vulnerability Index
The CDC/ATSDR Social Vulnerability Index (SVI) measures the relative social vulnerability of U.S. communities to disasters and public-health emergencies at the census-tract and county level. It combines 16 U.S. Census variables, grouped into four themes (socioeconomic status, household characteristics, racial and ethnic minority status, and housing type and transportation), into ranked vulnerability scores. Maintained by the CDC and the Agency for Toxic Substances and Disease Registry (ATSDR) through their Geospatial Research, Analysis, and Services Program (GRASP), the SVI helps public-health officials and emergency planners prepare for and respond to hazardous events. It serves as an upstream source for the KnowWhereGraph.
