The U.S. census is far more than a statistical snapshot of the country. Every ten years, the Constitution requires a count of every person living in the states, and the population totals that emerge from that count are used to redistribute seats in the House of Representatives and votes in the Electoral College—a process known as congressional apportionment. That decennial count effectively determines how much political power each state holds in Washington for the following decade, shaping everything from the size of a state's congressional delegation to the number of electoral votes it can cast in presidential elections.
NPR correspondent Hansi Lo Wang, who has covered the census for years, explains the mechanics of this process in a comic-style explainer. The core idea is straightforward: the census is not just a demographic exercise, but the foundation of the nation's system of representative government. Because the Constitution mandates a count of every person living in the states—not just citizens—the census has historically included all residents, regardless of immigration status.
That long-standing practice is now the target of a major proposed change. The Trump administration is attempting to alter who gets included in the apportionment counts. Specifically, it wants to exclude—for the first time in U.S. history—any resident who is not a U.S. citizen or a green-card holder. Under this proposal, undocumented immigrants and other noncitizens without permanent legal status would be left out of the population totals used to divide up House seats and Electoral College votes among the states.
The implications of such a shift would be significant. The proposal would make certain residents effectively invisible in the apportionment process. It could also shift political power away from states that have higher numbers of certain noncitizen residents, including people without legal status. States with large immigrant populations could lose congressional seats and electoral votes, while states with smaller noncitizen populations could gain influence—even if their overall resident populations are smaller.
The NPR explainer describes the apportionment process as a relay race. The runners in this race are the commerce secretary, who oversees the Census Bureau; the president; and Congress. The batons being passed between them are the state population counts and the House reapportionment numbers that flow from those counts. Each of these actors plays a distinct role in turning raw census data into the allocation of political power.
President Trump has pursued this change before. During his first term, he attempted to alter the census in ways that would have excluded undocumented immigrants from apportionment counts, but those efforts ultimately failed. Now, ahead of the 2030 census, he is trying again. The renewed push signals that the administration views the census as a venue for reshaping the political map—not merely a bureaucratic accounting exercise.
The proposal is expected to set off court battles. Legal challenges would likely center on the Constitution's requirement that apportionment be based on a count of "the whole number of persons in each state," language that has historically been interpreted to include all residents, not only citizens or lawful permanent residents. Immigration advocates and civil rights groups have long argued that excluding any residents from the count would violate both the letter and the spirit of the Constitution.
Beyond the legal questions, the debate raises broader issues about representation and fairness. The census determines not only congressional seats but also the distribution of federal funding for programs that serve communities across the country. If certain residents are excluded from the count, those communities could also see their share of federal resources diminished. The 2030 census, still several years away, is already emerging as a central battleground in the larger national debate over immigration and political power.
The original comic was first published in 2020 and again in 2021, and earlier versions have been updated to reflect the renewed effort by the Trump administration. That repetition itself underscores how persistent the issue has become. What began as a technical question about who is counted has evolved into a high-stakes constitutional fight over who is represented—and how much power their state wields in Congress and the Electoral College.
For now, the outcome remains uncertain. The administration's proposal faces likely legal challenges that could reach the Supreme Court. In the meantime, the census apparatus continues to prepare for the 2030 count, while states, advocacy groups, and legal scholars watch closely. The stakes are clear: the rules governing who is counted will help determine the balance of political power in the United States for years to come.
