The Trump administration has proposed significant reforms to the 2030 U.S. Census, planning to limit the count to U.S. citizens and permanent residents, excluding undocumented immigrants and temporary legal immigrants. Additionally, the proposal would eliminate race and ethnicity questions from the census. As census data determines congressional representation and the allocation of federal funds, these changes could significantly impact states with large immigrant populations. The proposal is now open for a 30-day public comment period and may face legal challenges.
