Voter Registration Statistics in Indian River County — Indian River County, Florida

Indian River County had 118,894 active registered voters on August 31, 2026, the latest month the Florida Division of Elections had posted by October 12, 2026, for the county that includes Sebastian, Vero Beach and Fellsmere (Division of Elections, August 2026).

Republicans hold a clear majority of the rolls kept by the Supervisor of Elections. The August 31 report lists 63,343 Republicans, 26,292 Democrats, 23,926 voters with no party affiliation and 5,333 minor party voters (Division of Elections). That makes Republicans 53.3% of active voters in the county (63,343 divided by 118,894), against 41.6% statewide, where the same report counts 5,649,410 Republicans among 13,580,124 active voters (statewide totals, row 72).

The neighbor to the south looks different. St. Lucie County, which begins below Vero Beach, had 95,442 Republicans and 80,361 Democrats among 243,831 active voters on the same date (Division of Elections, St. Lucie row), so Democrats were 33.0% of its rolls against 22.1% in Indian River County. The Division of Elections leaves the September to December 2026 sheets blank until it posts them, so the September and October month-end counts will appear there later.

Active voters in Indian River County rose from 117,141 on December 31, 2025 to 118,894 on August 31, 2026, a gain of 1,753, while the Supervisor of Elections' rolls lost 729 no party voters (December 2025, August 2026).

The arithmetic by party on the Supervisor of Elections rolls, December 31 to August 31: Republicans went from 61,719 to 63,343 (up 1,624), Democrats from 26,010 to 26,292 (up 282), minor parties from 4,757 to 5,333 (up 576) and no party affiliation from 24,655 to 23,926 (down 729) (Division of Elections, PriorDecember sheet). The Division's own net sheet measures from January 31 instead, and reports a net gain of 1,653 active voters in Indian River County, including 1,466 Republicans and a loss of 640 no party voters (Net-Year-to-Date sheet).

Most of the growth came in midsummer, in the weeks around the August 18 primary run by the Supervisor of Elections in Vero Beach. Between July 31 and August 31 alone the county added a net 579 active voters, 471 of them Republicans, while the no party group shrank by 150 (NetJulToAug sheet). From January 31 to May 31 the total barely moved, from 117,241 to 117,222 (January, May), before rising to 118,315 by July 31 (July).

From January through August 2026 the Division of Elections recorded 3,360 new valid voters and 2,005 active voters removed in Indian River County, where the Supervisor of Elections maintains the rolls for Sebastian, Vero Beach and Fellsmere (New and Removed Voters, year to date).

Monthly figures for the county around Sebastian and Vero Beach show the pace. January brought 379 new voters and 251 removals (January), July 504 new and 235 removed (July) and August 477 new and 201 removed (August). The year-to-date sheet shows no inactive-voter removals in Indian River County through August. New voters minus active removals comes to 1,355 for the eight months (3,360 minus 2,005), smaller than the 1,753 rise in active voters in the party report over the same months.

Driver license offices drive registration. Of 3,804 new registration and preregistration applications from Indian River County in 2026 through August, 3,364 came through the Department of Highway Safety and Motor Vehicles, 243 through online voter registration, 99 directly through the Supervisor of Elections and 95 by mail (Applications by Source, year to date). That is 88.4% through motor vehicle channels (3,364 divided by 3,804). In January alone, 400 of 431 applications came that way (January). In this county the Tax Collector lists driver license services, and its offices include the Sebastian Office at Sebastian Corners, 1921 U.S. Highway 1, and the Main Office at 1800 27th Street, Vero Beach (Indian River County Tax Collector).

Turnout reached 82.85% in the November 5, 2024 general election, with 100,155 ballots from 120,880 registered voters, and 29.05% in the August 18, 2026 primary, with 34,307 ballots from 118,078 voters, according to the Supervisor of Elections (2024 general, 2026 primary).

The 2024 general election was reported from 34 precincts and the 2026 primary from 36 (ENR archive, ENR archive). Both summaries are the official results posted by the Indian River County Supervisor of Elections, whose office at 4375 43rd Avenue in Vero Beach is open weekdays from 8:30 a.m. to 5:00 p.m. and answers at (772) 226-4700 (Supervisor of Elections).

The primary's registered count matches a frozen set of figures in the county registration data feed for Indian River. That feed lists frozen figures dated 2026-7-20 of 62,760 Republicans, 26,072 Democrats, 24,003 no party voters and 5,243 others (Indian River registration data feed). Those four add up to 118,078 (62,760 plus 26,072 plus 24,003 plus 5,243), exactly the registered total on the primary results page.

No official report splits Indian River County registration by party for Sebastian, but the City of Sebastian recall election of September 15, 2020 counted 20,550 registered city voters in 4 precincts (ENR archive, 2020 recall).

That election drew 6,401 ballots, a 31.15% turnout, from Sebastian voters alone (Supervisor of Elections ENR archive). A more recent Sebastian figure comes from a city ballot question. On November 5, 2024 the City of Sebastian charter referendum, reported by 5 precincts, drew 15,262 votes, 6,377 for approval and 8,885 for rejection (2024 general, ENR archive), on a ballot where countywide turnout was 82.85%.

The other cities appear the same way in the archive. In the 2024 general, the City of Vero Beach charter questions were reported by 3 precincts and the City of Fellsmere council race by 1 (ENR archive), so the results pages show where each city's voters sit inside the countywide total without giving a separate registered count.

Updated numbers come from two places. The Division of Elections posts each month's county party counts in its 2026 workbook, and the Indian River County Supervisor of Elections, led by Supervisor Leslie Rossway Swan, publishes official results for county and city elections in its results archive (Supervisor of Elections). Last verified: October 12, 2026, on the Florida Division of Elections 2026 workbooks for party affiliation (August, PriorDecember, January, May, July, Net-Year-to-Date Total and NetJulToAug sheets), new and removed voters (Year-to-Date Total, January, July and August sheets) and applications by source (Year-to-Date Total and January sheets), the Supervisor of Elections results archive pages for the August 18, 2026 primary, the November 5, 2024 general and the September 15, 2020 Sebastian recall, the Supervisor of Elections home page, the Indian River registration data feed, and the Tax Collector home page.
