As U.S. national elections are increasingly decided by narrow margins, the accuracy of voter list maintenance has become both consequential and controversial. In June 2024, Ohio officials publicly announced the scheduled removal of 158,857 voter registrations as part of its routine list maintenance process. This study evaluates the accuracy of that removal effort by tracking changes to voter registration records over a five-month period using weekly snapshots of Ohio’s voter data. We introduce the Erroneous Removal Rate (ERR)—defined as the percentage of voters who were removed but later reappeared on the rolls under the same name and address—to quantify the extent to which eligible voters may have been flagged for removal.
