of every census tract. The SVI ranks eachcensus tracton 15 social factors, including poverty, lack of vehicle access, and
crowded housing, and groups them into four related themes:</div><div><ul><li>Socioeconomic</li><li>Housing

ranked census tracts for the entire United States against one another. This feature layer can be used for mapping and analysis
of relative vulnerability of census tracts in multiple states, or across the U.S. as a whole. Census tractrankings are based
on percentiles. Percentile ranking values range from 0 to 1, with higher values indicating greater vulnerability. For each
census tract, we generated its percentile rank among all census tracts for 1) the fifteen individual variables, 2) the four
themes, and 3) Its overall position.</div><div><b><br /></b></div></div><div><b>Overall
Rankings:</b></div><div><div>We summed the sums for each theme, ordered the census tracts, and then
calculated overallpercentile rankings. Please note; taking the sum of the sums for each theme is the same as summing individualvariable
rankings.</div><div><br /></div><div>The overall tract summary ranking variable is RPL_THEMES.</div><div><br
/></div><div><div><div><b>Theme rankings:</b></div><div>For each of the
four themes, we summed the percentiles for the variables comprising eachtheme. We ordered the summed percentiles for each
theme to determine theme-specific percentile rankings.The four summary theme ranking variables are:</div></div><div><ul><li>Socioeconomic
theme - RPL_THEME1<br /></li><li>Housing Composition and Disability - RPL_THEME2<br /></li><li>Minority
Status &amp; Language - RPL_THEME3<br /></li><li>Housing &amp; Transportation - RPL_THEME4</li></ul></div></div><div><br
/></div><div>Flags</div><div>Census tractsin the top 10%, i.e., at the 90th percentile of values,
are given a value of 1 to indicate high vulnerability. Census tracts below the 90th percentile are given a value of 0. For
a theme, the flag value is the number of flags for variables comprising the theme. We calculated the overallflag value for
each census tract as the number of all variable flags.</div><div><br /></div></div><div><div><b>SVI
