What the numbers say
Absentee ballots received, by days before Election Day
Cumulative statewide absentee ballots received by county auditors. In Iowa this includes in-person early votes (voted at the auditor's office or a satellite site) as well as mail ballots. 2026 in bold; dots = actual daily SOS reports (weekdays only, no interpolation; lines just connect reports).
Ballots added per report: last 7 reports
Change between consecutive 2026 SOS reports. A Monday report includes the weekend.
Same point in the early-voting period
Ballots received N days after early voting opened (20-day period in 2022–2026; 29 days in 2018, so 2018 opened earlier).
Who has returned ballots (registered party)
Share of ballots received, by party registration, at the closest report to the same days-out.

Data coverage & gaps
Sources & caveats
- Iowa counts in-person early voting as absentee voting, so "received" = mail ballots received + in-person early votes. Past-cycle reports don't split out the method statewide.
- 2018 isn't directly comparable: Iowa's early-voting window was 29 days (opened Oct 8, 2018). It was cut to 20 days starting in 2022, so 2018 had a much bigger head start at the same days-out.
- Reports post on weekday mornings (data pulled ~3–4 AM ET) and replace the previous day's file. Each point is dated by the report date. Past cycles come from SOS archive PDFs that bundle every daily report.
- Party = voter registration (Democrat, Republican, No Party; Libertarian/Green/other grouped as Other). Party splits are shown only where the county lines add up exactly to the state total.
- When the SOS posted two versions on the same date, the later (larger) one is used.
Law changes that affect comparisons
Iowa shortened its early-voting window in 2021, so 2018 had a longer runway than 2022 and 2026.
- 2021 · Senate File 413: early in-person voting and mailing of absentee ballots now start 20 days before Election Day (was 29); absentee ballots must be received by the county auditor when polls close on Election Day; counties can't mail absentee request forms unless the voter asks. Compare 2018 at the same days-out with care. Iowa Legislature: SF 413 · Scott County Auditor summary
