Social vulnerability refers to factors such as poverty, access to transportation, and housing conditions that may affect a community’s ability to avoid human suffering and economic loss during disasters, including those related to climate change. This tool ranks U.S. census tracts (subparts of counties) on 14 variables and maps them across four themes: socioeconomic status, household composition, race/ethnicity/language, and housing/transportation. These data can be used by local officials to identify communities that may need support in preparing for hazards or in recovering from disaster.
