2030 Electoral College Projections: Seat Shifts and Drivers

The 2030 electoral college projections point to a clear southward shift: Texas, Florida, and other Sun Belt states are on track to gain House seats and electoral votes after the 2030 census, while California, New York, Illinois, and several Northern states are projected to lose them. Three major forecasts published in early 2026, from Jonathan Cervas of Carnegie Mellon University, the American Redistricting Project, and the Brennan Center for Justice, largely agree on the direction and roughly agree on the magnitude.¹

Which States Are Projected to Gain Seats

Texas leads the projected gainers with four additional House seats. Florida is projected to gain between two and four, depending on assumptions about immigration and domestic migration.¹²

Five more states appear as one-seat gainers across all three models: Georgia, North Carolina, Arizona, Utah, and Idaho. An earlier 2023 Brennan Center analysis also flagged South Carolina and Tennessee as possible one-seat gainers, but those states dropped out of the more recent 2026 projections and are considered marginal.³

Some of these seats are on a knife’s edge. Esri, a geospatial data firm using its own cohort-component modeling, found that Georgia’s projected 15th seat could vanish if the 2030 count falls short by about 35,000 people, and Michigan’s 13th seat hinges on a margin of roughly 4,100.⁴ The American Redistricting Project identifies six “bubble” seats that could flip on small shifts, including the last seats currently projected for Michigan, Texas, and Georgia.⁵

Which States Are Projected to Lose Seats

California is the biggest projected loser, expected to shed four seats. That would drop the state well below the 52 it held after the 2020 census.⁶

New York is projected to lose one to two seats, and Illinois one to two, with the exact number depending on the model. Oregon, Minnesota, Wisconsin, Pennsylvania, and Rhode Island are each projected to lose one seat.¹

By 2030, the Brennan Center projects that California, New York, and Illinois together will have congressional delegations roughly half the size they were in the 1930s and 1940s.³

What This Does to the Electoral Vote Totals

Each House seat gained or lost translates directly into an electoral vote, since a state’s electoral vote total equals its House seats plus its two senators. Under a projected 2032 map published by 270toWin, Texas would hold 43 electoral votes (up from 40), Florida 32 (up from 30), and Georgia 17 (up from 16). California would drop to 51 (from 54), New York to 27 (from 28), and Illinois to 17 (from 19). Pennsylvania would fall to 18 from 19, and Minnesota and Wisconsin would each drop by one.⁷

How the Presidential Math Changes

A February 2026 analysis by Geoffrey Skelley of DecisionDesk HQ re-ran the 2024 presidential election on the projected 2032 map. Donald Trump’s Electoral College margin over Kamala Harris would have grown from 312–226 to 322–216, a net ten-vote gain for the Republican column.⁸

The path-to-270 implications matter more than the topline. On the current map, a Democrat can carry the Blue Wall trio of Michigan, Pennsylvania, and Wisconsin along with the states Harris won and reach exactly 270. On the projected 2032 map, that same combination yields only 258, falling 12 short. The tipping-point state also shifts from Pennsylvania to Georgia.⁸

The Brennan Center illustrates the same squeeze from another angle. A Democrat who wins the traditional Blue Wall plus Arizona and Nevada would win 276–262 on the projected map, a thinner cushion than the same coalition delivers today.²

Adam Kincaid, president of the National Republican Redistricting Trust, has described the emerging map as a potential “Red Wall” built on Arizona, Georgia, and North Carolina, one that could let Republicans win the White House without carrying any Rust Belt states. He has also cautioned against reading the shifts as decisive, saying reapportionment “changes our campaigns like apportionment always does” without predetermining outcomes.¹⁹

What Is Driving the Shift

The South has been the country’s primary population growth engine since 2020, adding nearly 3.9 million residents and accounting for the vast majority of national gains. Texas, Florida, Georgia, and North Carolina alone represent more than 90 percent of that regional growth, with Texas and Florida together responsible for about 70 percent. If current trends hold, the South is projected to become the most populous region in the country by 2030, home to nearly four in ten Americans.³

Northeastern and upper Midwestern states have seen flat growth or outright declines. The result is a steady, decades-long transfer of House seats and electoral votes from those regions to the Sun Belt.

What Could Still Change the Projections

Every analyst studying 2030 reapportionment stresses that five years of population change remain before the actual count. Several factors could meaningfully move the numbers.

Immigration

Immigration is the largest single driver of growth in the projected gainer states. Between 2024 and 2025, immigration accounted for more than 90 percent of Florida’s population growth and 44 percent of Texas’s. The Brennan Center modeled a zero-immigration scenario for the rest of the decade and found that Florida’s projected gain drops from three seats to two and Wisconsin, currently projected to lose a seat, keeps it.⁶

Texas already saw immigration fall nearly 50 percent between 2024 and 2025. State demographer Lloyd Potter has said potential immigrants are becoming “more reticent” given heightened enforcement, which could dampen growth going forward. William Frey of the Brookings Institution has estimated that under a sharply curtailed immigration scenario, Texas might gain three seats instead of four, and California’s losses could be held to three instead of four.¹⁰

A Citizen-Only Apportionment Base

A larger wildcard is whether Congress or the executive branch changes who gets counted for apportionment. The Constitution has historically been interpreted to require counting all persons, and the Supreme Court has never directly ruled on excluding noncitizens from the apportionment count.¹¹ Several bills in the 118th Congress proposed a citizen-only base.

The Fair Lines America Foundation modeled apportionment using citizen-only figures from the American Community Survey. Under that approach, California would lose six seats instead of four, Texas and Florida would each gain two, and states like Ohio, Tennessee, and Georgia would pick up seats they are not otherwise projected to gain.¹² Whether such a change is legally or politically achievable is unresolved.

Census Accuracy

The accuracy of the 2030 count itself is in question. A June 2026 Government Accountability Office report found the Department of Commerce had cut the Census Bureau’s planned 2026 practice test from six sites to two, both in the South, eliminating test locations on tribal lands in Arizona, in rural western North Carolina, in western Texas, and in Colorado Springs. Ten of 19 planned operational activities were scaled back or cut, and the questionnaire was changed to an English-only version with a new citizenship question.¹³

Mark Mather of the Population Reference Bureau called the cuts “a step backward” and said the Bureau would be “essentially flying blind into communities that need testing most.”¹⁴ Undercounts have historically swung apportionment. Aggressive outreach helped New York retain a seat it was projected to lose in 2020, while Texas gained fewer seats than expected after a less robust effort.²

A Sun Belt Slowdown

Florida, the second-biggest projected gainer, is already seeing domestic in-migration slow as housing costs, insurance premiums, and climate concerns bite.¹⁵ Kincaid himself has acknowledged the uncertainty: “I don’t think anybody rationally expects Florida and Texas to grow as rapidly through the decade as they did during COVID.”¹⁰

How Reapportionment Produces These Numbers

The 435 House seats are redistributed among the states every ten years after the census. Each state is guaranteed one seat, and the remaining 385 are allocated by the “method of equal proportions,” a formula Congress adopted in 1941 that ranks states by priority values derived from their populations.¹⁶ Because a state’s electoral vote equals its House seats plus two senators, the reapportionment that follows the 2030 census determines the Electoral College map used starting in 2032.

The projections above are mid-decade estimates, and analysts describe them uniformly as “halftime” figures. What is consistent across every model is the direction: political weight in the Electoral College is shifting south, and the presidential math of the 2030s will not look like today’s.
