Trump Census Plan Could Be Trouble For GOP

A Trump administration proposal involving how immigrants are counted for congressional representation could have an unexpected effect on some Republican-led states after the 2030 Census.

Rather than automatically helping states that typically vote Republican, an analysis published by The New York Times found that excluding certain noncitizens from the population used to divide seats in the U.S. House could potentially cost Texas and Florida congressional representation.

The finding adds a surprising twist to a growing national debate over immigration, the census and political power.

Texas Could Miss Out on an Additional House Seat

Under one set of population estimates examined in the analysis, Texas would receive one fewer House seat than it would if the entire resident population were counted for apportionment.

Florida could also receive one fewer seat.

Meanwhile, states including Minnesota and Oregon could benefit under the same scenario.

Different demographic estimates produced somewhat different results, underscoring how much could change before the 2030 Census.

Population growth, immigration trends and Americans moving between states will all affect the eventual numbers.

Still, the analysis demonstrates an important point: excluding certain immigrants from congressional apportionment would not necessarily benefit one political party in a predictable way.

Why Texas and Florida Could Be Hit Hard

Texas and Florida have experienced substantial population growth in recent years, including growth in their immigrant populations.

Pew Research Center estimated that approximately 2.1 million unauthorized immigrants lived in Texas in 2023, making it second only to California.

Florida had an estimated 1.6 million unauthorized immigrants, the third-highest total in the country.

That means a policy excluding large categories of noncitizens from apportionment totals could remove a significant number of residents from the calculations in both states.

Pew also found that unauthorized immigrants have become less concentrated geographically over time.

In 1990, the six states with the largest unauthorized immigrant populations accounted for about 80% of the national total. By 2023, those six states accounted for approximately 56%.

That shift helps explain why changes to census counting rules could now affect a wider range of states.

Why the 2030 Census Matters

The census determines much more than the country’s population.

Every 10 years, census results are used to divide the 435 voting seats in the U.S. House of Representatives among the 50 states.

That process is known as congressional apportionment.

States experiencing faster population growth can gain House seats, while states growing more slowly can lose representation.

The census also affects the drawing of congressional and legislative districts and helps inform the distribution of trillions of dollars in federal funding for programs including roads, schools, hospitals and emergency services.

Because House representation also contributes to the number of Electoral College votes a state receives, changes in apportionment can have national political consequences.

Even Small Population Differences Can Matter

Congressional apportionment can sometimes come down to extremely narrow population differences.

After each census, all 50 states compete mathematically for the same 435 House seats.

Once every state receives its constitutionally required minimum of one representative, the remaining seats are distributed according to a mathematical formula based on population.

That means relatively small changes in a state’s population total can determine whether it gains or loses a seat.

For states growing rapidly, every resident included in the apportionment count can potentially matter.

Constitutional Questions Could Loom Large

Any major change to which residents are included in congressional apportionment would likely generate significant legal challenges.

Section 2 of the Fourteenth Amendment states that House representatives are apportioned among the states according to their respective populations, based on “counting the whole number of persons in each State.”

The constitutional language refers to “persons,” rather than only citizens.

The Census Bureau’s current apportionment methodology includes each state’s total resident population, along with certain federal employees and dependents living overseas who identify that state as their home state.

Whether a future administration can constitutionally exclude particular categories of residents from the population used for House apportionment could therefore become a major question for the courts.

Immigration Has Shifted Across the Country

Another factor complicating the political impact is where immigrants now live.

Large immigrant populations are no longer concentrated primarily in California and New York.

Pew estimated that the six states with the largest unauthorized immigrant populations in 2023 were California, Texas, Florida, New York, New Jersey and Illinois.

Florida experienced especially rapid growth.

Pew estimated that its unauthorized immigrant population increased by roughly 700,000 between 2021 and 2023.

Texas increased by about 450,000 during that same period.

Those demographic changes mean immigration-related census policies can affect both Republican-led and Democratic-led states.

Congressional Maps Are Already a Major Political Battleground

The census debate comes during an increasingly intense national fight over congressional districts.

After every decennial census, states redraw congressional boundaries to reflect changes in population.

Some states give lawmakers significant authority over that process, while others rely on commissions or other systems.

The result can have major consequences for control of the U.S. House.

Redistricting disputes have also increasingly moved into state courts following a major Supreme Court ruling.

In its 2019 decision in Rucho v. Common Cause, the Supreme Court held that claims involving excessive partisan gerrymandering present political questions that federal courts cannot resolve under existing constitutional standards.

State laws, state constitutions and state courts can still place restrictions on how congressional maps are drawn.

The Political Impact May Be Hard to Predict

Supporters of changing census apportionment rules argue that congressional representation should more closely reflect citizens or lawful permanent residents.

Opponents point to the Fourteenth Amendment’s reference to the “whole number of persons” living in each state.

The political consequences could also be far less straightforward than supporters or opponents expect.

A state could support tighter immigration policies while simultaneously losing congressional representation if large numbers of its residents were excluded from apportionment.

Texas and Florida are among the clearest examples of that possibility.

Both states have grown rapidly and gained significant political influence in recent decades.

But both also have large immigrant populations that could potentially be affected by a change in counting rules.

What Happens Next

The 2030 Census remains several years away, and the final population picture could look very different from today’s estimates.

The Census Bureau is already planning for the nationwide count, which will determine the distribution of House seats for the following decade.

Immigration levels, domestic migration, birth rates and economic conditions could all change the projections before then.

Legal challenges could also determine whether any proposed changes to congressional apportionment can take effect.

For now, the emerging debate shows how closely immigration policy and political representation have become connected.

And if current demographic estimates are any indication, changing who is included in congressional apportionment could produce consequences that cut across traditional Republican and Democratic state lines.
