Sherburne County Multi -Hazard Mitigation Plan, 2020 <br />as "...the resilience of communities when confronted by external stresses on human health, stresses <br />such as natural or human -caused disasters, or disease outbreaks" (2oi8). These stressors now <br />increasingly include the more extreme weather events and longer -term impacts of Minnesota's <br />changing climate. <br />Reducing social vulnerability can decrease both human suffering and economic loss. The ATSDR Social <br />Vulnerability Index (SVI) uses U.S. Census variables at the tract -level to help local officials identify <br />communities that may need support in preparing for hazards or recovering from disaster. Certain social <br />conditions, such as high poverty, low percentage of vehicle access, or crowded households can increase <br />a community's social vulnerability (ATSDR, 2o3.8). <br />The ATSDR SVI ranks census tracts on 3.5 social factors which are grouped into four themes (Table 6). <br />Table 6. Social Vulnerabilitil Index (SVI) Variables <br />Proportion individuals below poverty level <br />Socioeconomic <br />Proportion civilians unemployed i6+yrs <br />Status <br />Per capita income in 1999 <br />_ <br />Proportion persons with no high school diploma 25+yrs <br />Household <br />Proportion persons 65 years or older <br />Composition & <br />Proportion persons 1.7 years or younger <br />Disability <br />Proportion persons with disability 5+yrs <br />Proportion single -parent HH with children under 1.8 yrs <br />Minority Status <br />Proportion minority <br />& Language <br />Proportion persons 5+yrs who speak English less than 'well' <br />Proportion housing with io+units <br />Proportion mobile home <br />Housing & <br />Proportion HH with more people than rooms <br />Transportation <br />Proportion HH with no vehicle access <br />Proportion of persons who are in institutional & non - <br />institutional group quarters <br />Source: (CDC, 2019) <br />Census tracts within Minnesota were ranked and given a percentile value from oto i, with highervalues <br />indicating greater vulnerability. Theme -specific percentile rankings were generated by summing the <br />percentiles of the variables comprising each theme and ordering the summed percentiles for each <br />theme.
