An arrow chart showing the percent of the 16+ population that has received at least one COVID-19 vaccine dose on May 1 and June 4, by high-risk ZIP codes in Minnesota as defined by the CDC's Social Vulnerability Index. One group shows the top 10 ZIP codes that have seen the greatest percent increase in that time period -- most of which are in the Twin Cities metro -- and the other shows the 10 ZIP codes with the smallest increase, all of which are in rural Minnesota.
