Florida – Voter Age by Precinct

This is part 2 of the Florida Map Series. See part 1 here. 

Explore Florida’s Voters

I analyzed all active registered voters in Florida by age, then calculated the largest (median) age group per precinct. The curious can see a short description of my process and the SQL I wrote to generate this map. This map was not created for, or endorsed by, any political party or candidate.
