How is the Social Vulnerability Index Classified and Displayed?
The SOVI™ was created as a comparative index at a county-level for the entire United States. Therefore, the SOVI™ scores need to be displayed in relation to each other. Generally, the SOVI™ is classified using standard deviations. Social vulnerability scores that are greater than 2 standard deviations above the mean are considered the most socially vulnerable, and scores below 2 standard deviations less than the mean are the least vulnerable.
