Substance Use Vulnerability Index Score (MI-SUVI)

The MI-SUVI score is a measure of vulnerability to adverse substance use outcomes. The score measures how far above or below a county’s substance use vulnerability is from the county average across Michigan. For example, if a county has a score of 2.5, that means that the county’s score is 2.5 times above the average county score for Michigan. A higher score means there is higher substance use vulnerability in the community. The MI-SUVI does not describe “good” or “bad” counties with regards to substance use, but rather indicates the extent to which a county has been impacted in comparison to other counties.

The MI-SUVI score consists of 8 data indicators grouped into 3 categories (Substance Use Burden, Substance Use Resources, and Social Vulnerability) that make up the total score.

• Substance Use Burden: negative outcomes associated with SUD that place a burden on individuals and community resources such as the healthcare and justice systems.
• Substance Use Resources: resources available to the community that can be used to address the negative outcomes associated with SUD.
• Social vulnerability: a measure of community level characteristics known to be important drivers of health (i.e., social determinants of health).

The substance use vulnerability index score (MI-SUVI) for Port Huron residents is 0.6 and -0.1 in St. Clair County. This means that Port Huron and St. Clair County residents have been similarly impacted by substance use disorder compared to other residents across the state.

St. Clair County is the 46th most vulnerable to substance use (out of the 83 counties in Michigan. St. Clair County ranks 11th in substance use burden, 19th in substance use resources, and 59th in social vulnerability.
