Purged voter count data by ZIP (Postal) code from the Ohio Secretary of State's website (https://registrationreadiness.ohiosos.gov/#). Voting age population data is from the 2022 American Community Survey published by the US Census.
Context?
Without knowing how this compares to other states, which areas have higher counts of rental properties, how other states compare, and things like average or percentage of: ages, incomes, ethnicities, and probably party affiliation, this doesn't tell us much by itself.
I am encouraged that it is given as a percentage of the voting population instead of a numeric count (XKCD's pet peeve #208), but it still looks a lot like a population map. I had to find a straight population map to compare where it differs, and as a quick visual trend they are similar. From https://www.someka.net/blog/ohio-zip-code-map/ :
Overlap that with an income map (from https://proximityone.com/srdmi/ohdmi.htm):
With only a visual examination, I still have little idea of what the map says about voter purging. I can't tell if old people are getting purged as they die, if college students are getting purged as they fail to change from their school address, or if a particular party is getting purged just to sway elections.
