The Trump administration has introduced a far-reaching proposal to reshape how the United States conducts the 2030 Census, arguing that congressional representation should better reflect the nation's permanent resident population. If approved, the changes would significantly affect how House seats are apportioned among the states and how federal resources are distributed.

At the center of the proposal is a revised definition of "usual residence." Under the new approach, undocumented immigrants would no longer be included in the population totals used to allocate seats in the U.S. House of Representatives. The Census Bureau is also considering excluding certain non-citizens who are legally in the country but do not hold lawful permanent resident status, such as green cards.

According to the administration, the proposal is intended to ensure that congressional representation is based on individuals who have a lasting legal connection to the United States. Census officials argue that people without permanent legal status may not meet the standard of having a sufficient and enduring tie to the country for apportionment purposes.

The proposal also seeks to simplify the decennial census by removing questions related to race, ethnicity and sexual orientation from the standard questionnaire. The administration says demographic information could still be obtained through administrative records and other federal surveys, while reducing questions it considers unnecessary or sensitive.

If implemented, the changes would have broad implications. Census data determine how the 435 seats in the House of Representatives are divided among the states, influence the redrawing of congressional and legislative districts, and help guide the distribution of hundreds of billions of dollars in federal funding each year.

The proposal revives an issue that has been the subject of legal and political debate for years. During Trump's first term, the administration pursued similar efforts related to census methodology, though those initiatives were ultimately not implemented. The new proposal is expected to face legal challenges, with opponents arguing that the Constitution requires the census to count all persons residing in each state for apportionment purposes.

Before any changes take effect, the proposed rule will go through a public comment period and the federal rulemaking process, meaning the policy is not yet final. Any final version could also be subject to judicial review before the 2030 Census begins.
