Description: The CDC\ATSDR Social Vulnerability Index (SVI) is a tool, created by the Geospatial Research, Analysis and Services Program (GRASP), to help public health officials and emergency response planners identify and map the communities that will most likely need support before, during, and after a hazardous event. The tract-level SVI shows the relative vulnerability of every CALIFORNIA tract population. The SVI ranks counties on 15 social factors, described in detail in the documentation. The tract rankings for individual factors are further grouped into four related themes. Thus each enumeration unit receives a ranking for each Census variable and for each of the four themes, as well as an overall ranking. For full documentation visit https://www.atsdr.cdc.gov/placeandhealth/svi/documentation/SVI_documentation_2018.html. For additional questions, contact the SVI Lead at SVI_Coordinator@cdc.gov.
