SVI values from the CDC range between 0 and 1 based on their percentile position among all census tracts in the U.S. with 0 representing lowest vulnerability census tracts and 1 representing highest vulnerability census tracts. SEDAC has gridded these vector inputs to create 1 km spatial resolution raster surfaces allowing users to obtain vulnerability metrics for any user-defined area within the U.S. Read full documentation [pdf].
