Researchers focused on 10 categories related to voting, including registration, inconvenience, early voting, polling hours and absentee voting.
The state also stopped using special voting deputies, officials whose tasks had sometimes included conducting voter registration drives, according to the study.
To assess the voting laws passed after the 2020 election, this year’s Cost of Voting Index study added new categories and scoring.
While the political debate surrounding new election laws has centered on ballots and the voting process, the Cost of Voting Index also gives heavy weight to the ease of voter registration.
States rank higher in the index if they allow voter registration drives, provide automatic voter registration, offer same-day registration and maintain longer periods in which to register.
