For at least the 2000 version of SVI, the metric is derived from summed percentile rankings at census tract level of fifteen U.S. Census variables shown in the following table:
| SVI Theme | Variables Included |
|---|---|
| 1. Socioeconomic Status | % Below Poverty Level |
| % Unemployed | |
| Per Capita Income | |
| % Age 25 or Older with No High School | |
| 2. Household Composition & | Diploma |
| Disability | % Age 65 or Older |
| % Age 17 or Younger | |
| 3. Minority Status & Language | % Single Parent Household |
| % Age 5 or Older Speak English "Less than | |
| 4. Housing & Transportation | Well" |
| % Multi-Unit Structures | |
| % Mobile Homes | |
| % Crowding (More people than rooms) | |
| % Households without a Vehicle | |
| % In Institutionalized Group Quarters |
These variables were determined from an extensive literature review [19,20,23,29, 30]. <!–TODO: Get references from this file–> The SVI is normalized between 0 and 1 with 0 representing low social vulnerability and 1 representing high social vulnerability.
