Midterm to midterm: 2014, 2018 and 2022
Midterm elections are held halfway through a president's term, and fewer people vote in them than in presidential years, so the fairest comparison is with other midterms.

How this archive is built
The U.S. Election Assistance Commission asks every local election office to complete the Election Administration and Voting Survey after each November general election. In 2026 the commission published all 11 surveys from 2004 to 2024 as one combined file, with consistent column names and county versions of the data. This page reads that county file and changes nothing in it except where noted below.
- A number is what the local office reported. The commission uses four codes for no number: not reported, does not apply, skipped, and not asked that year. The page shows each as a sentence.
- A state or national total adds up only the places that reported that line. When some did not, the total is marked partial and says how many places reported.
- This site withholds a figure when it contradicts the same county's other answers: more mail ballots returned than sent, many more ballots counted than registered voters, or polling places far above the county's own precinct count. Those cells say so. 1665 figures across all years are withheld.
- Counties in Connecticut, Maine, Massachusetts, New Hampshire, Rhode Island and Vermont, and in Wisconsin from 2012, are built by the commission from town or municipal reports. Connecticut's counties are the former counties the commission used, not the planning regions the Census Bureau now lists.
- Polling place counts are not the same in every year: before 2018 the survey counted early-voting sites with Election Day sites, and the survey did not ask for a total in 2018 and 2020.
- The data holds counts for places only. There is no voter-level information.
