Summary table[]

Regularly-scheduled elections were held in 87 of the 99 state legislative chambers in the United States; nationwide, regularly-scheduled elections were held for 6,064 of the 7,383 legislative seats. Most legislative chambers held elections for all seats, but some legislative chambers that use staggered elections held elections for only a portion of the total seats in the chamber.^[1] The chambers that were not up for election either hold regularly-scheduled elections in odd-numbered years, or have four-year terms and hold all regularly-scheduled elections in presidential election years.

Note that this table only covers regularly-scheduled elections; additional special elections took place concurrently with these regularly-scheduled elections.
