Registration Numbers

Historical month-by-month voter registration totals are available on this page.

NOTE: Beginning on August 31, 2021, voter registration totals were pulled on the last day of each month. Previously, voter registration totals were pulled on the first day of each month. As a result of that change, there were two entries for August 2021: one from the first day of the month and one from the last day of the month.
