Social vulnerability refers to factors that can weaken how a community responds to a disaster, such as poverty, lack of transportation access, and crowded housing. Using U.S. Census data, the Social Vulnerability Index (SVI) identifies and maps the social vulnerability of counties and census tracts, which can help agencies improve their preparation and response to emergency events.
