As 2023 coincides neither with the calendar for regular federal elections nor with most elections for state offices (save for Kentucky, Louisiana, Mississippi, New Jersey and Virginia), most 2023 ballot measures either coincided with municipal or judicial elections or were held on separate dates as the sole questions on the ballot. With 47 ballot measures sent to the statewide ballot in multiple states, 2023 had the highest number of statewide ballot measures approved for the ballot in an odd-year election since 2007, when 45 measures (four citizen initiatives, 41 legislative referrals) were certified for statewide ballots. Ballot measures were also held at the local and tribal level.
