Minnesota

but we had a lot of early voting (technically "no excuse absentee voting" here) and quite a bit of that is mail in, though we can also vote early in person.

It would be interesting to know how the stats were calculated.

I did find this at the MN Secretary of State website.

"Number of Eligible Voters
Minnesota uses the number of the Voting Eligible Population (VEP) as the denominator when calculating the percentage
of voters who voted.
The VEP is the number of individuals 18 years of age or older (the voting age population) minus the estimated number of
individuals who are not eligible to vote (such as non-citizens or individuals who do not have voting rights under law).

In 2018, Minnesota’s current estimated Voting Eligible Population is 4,064,389.* "

Interesting that eligible voters who are not necessarily registered voters is used for the denominator. The way they arrive at it gives this data analyst a headache.
