I wish I knew. I had questions about Rochester (New York? Minnesota, home to the Mayo Clinic?) until I realized our local Rochester doesn't have the population necessary to meet the minimum requirement. I looked through their webpages for a spreadsheet of details for each location and score, but there's only what's on their webpage. It doesn't inspire confidence in their ratings, honestly, but I'm still glad to see Minneapolis recognized in a review that includes matters of social and environmental concerns.
