Census Bureau Proposes 2030 Rule Changing Residency, Apportionment Rules

In a resource brief, State Health and Value Strategies examines a Census Bureau proposed rule, published September 10, 2026, that would overhaul 2030 Census residence criteria and demographic data collection, alongside a new Disclosure Avoidance Order changing privacy protection methods for public data products. The residency proposal would exclude many non-citizens from population counts and establish a new January 3–April 1 enumeration period, while also excluding undocumented immigrants and other groups from congressional apportionment counts. State health agencies rely on Census products like the American Community Survey and Current Population Survey for Medicaid and CHIP funding formulas, coverage monitoring, disparity analysis, and program cost projections. Comments on the proposed rule are due October 13, 2026, giving states a limited window to weigh in on changes that could ripple through health policy data infrastructure.
