  • Social vulnerability refers to the resilience of communities when confronted by external stresses on human health, stresses such as natural or human-caused disasters, or disease outbreaks.
  • ATSDR’s Social Vulnerability Index uses U.S. census variables at tract level to help local officials identify communities that may need support in preparing for hazards, or recovering from disaster.
  • The CDC SVI ranks each tract into four themes: socioeconomic status, household composition, race/ethnicity/language, and housing/transportation. Also, gives an overall SVI.
  • Each tract receives a separate ranking for each of the four themes, as well as an overall ranking. Rankings can be US-wide or state-wide.
