Social Vulnerable Index

Social Vulnerable Index (SVI)

CDC defines Social Vulnerability Index as “the resilience of communities when confronted by external stresses on human health, stresses such as natural or human-caused disasters, or disease outbreaks. Reducing social vulnerability can decrease both human suffering and economic loss. CDC's Social Vulnerability Index uses 15 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.”

Possible SVI scores range from 0 (lowest vulnerability) to 1 (highest vulnerability). To access the score from census tracts located in Polk County, click in the area of interest in the map.  A pop-up window will indicate score and additional population socio-economic census data.
