Voter registration lists — or voter rolls — are an important component of a well-functioning election administration system. All states must maintain their voter rolls to keep them accurate, and there are acceptable methods for doing so, like removing voters who have moved or died. However, a number of states have put in place list maintenance practices that erroneously remove otherwise eligible voters from the rolls for improper reasons such as inactivity.
The resources on this page provide overviews of list maintenance practices across the states as well as track the rise of improper voter roll purges that often target marginalized communities.
