Census 2010 tract data

Often an optional parameter in fire incident reports, the ability to link fire data to census geographies provides access to a wealth of demographic and economic factors. Further technical documentation regarding the 2010 census data and corresponding geometries can be found in the Census 2010 TIGER/Line Shapefiles dataset.

Social Vulnerability Index (SVI)

The Social vulnerability index is a collection of pre-processed variables from the American Community Survey (ACS) that are subsequently ranked by percentile either within states or nationally. The variables used have been selected based on apparent correlation in literature with the ability of a family to recover from a catastrophic event. For the summary metrics, the closer a value is to 1, the more vulnerable to catastrophe families in that area are based on the underlying ACS characteristics.
This index is maintained by the CDC and the SVI 2016 Documentation is publicly available.

SVI Themes

The Social Vulnerability Index is comprised of an overall vulnerability score calculated using four underlying "themes", which are themselves determined using logical groupings of ACS variables.

Note that “Minority” here is defined by the CDC’s processing of the ACS racial characteristics as “Any non-white race.”
