Congress moves to strip House seats from high-immigration states via census redefinition.

What it does

This bill excludes noncitizens from the population count used to apportion House seats among states, requires the Commerce Secretary to revise the 2020 census data by January 2027 to remove noncitizens, and mandates that all future decennial censuses include a citizenship question. States that lose population due to noncitizen exclusion will lose House seats; states that gain or retain seats will benefit. The bill also creates expedited judicial review and federal court jurisdiction for any legal challenges.

Why we flagged it

The bill's core mechanism is not a new census but a retroactive redefinition of the 2020 census population base to exclude noncitizens, triggering a reapportionment of House seats. This is a structural shift in how representation is calculated, not a routine census or apportionment procedure.

What the text implies

• The bill presumes apportionment changes are lawful and requires 'clear and convincing' evidence to overturn them—a standard higher than typical administrative law review, potentially insulating the reallocation from constitutional challenge.
• Expedited judicial review and three-judge panels are designed to fast-track litigation to the Supreme Court, suggesting the drafters anticipate constitutional challenges and want to resolve them quickly before implementation.
• The citizenship question on future censuses will create a permanent record of noncitizen population by state, enabling future apportionments to exclude noncitizens without requiring new census data collection.
• States are required to provide immigration and citizenship data to Commerce Secretary; the bill does not specify privacy protections or limits on use of that data beyond apportionment.
• The bill applies to the 2020 census retroactively (revision by Jan. 2027) and prospectively (2030 census onward), creating two separate apportionment bases and potentially two different House seat allocations depending on which census is used.

Who it affects

Citizens in states with higher noncitizen populations lose House representation and thus voting power, while citizens in states with lower noncitizen populations gain representation. This is a zero-sum reallocation of democratic power based on immigration status, not citizenship status of voters. The bill also creates a presumption of validity for apportionment changes and a high bar (clear and convincing evidence) for courts to overturn them, insulating the reallocation from judicial review and
