Rank is derived by Quadranac: 1 = highest value; ties share a rank. The ranked value is itself derived; see the source table for the method. Values are as published in the source table.

Note: Enrollees are counted at their mailing address, so states with many seasonal residents may differ from where people live most of the year.
