Why It Matters
The Constitution requires a periodic census to apportion political representation among states. But by scaling back on a key test which followed a Department of Commerce review, the Census Bureau risks missing critical information about whether certain design features will actually work when the next count happens in four years.
The 2026 Census Test is the first of two major field tests meant to help the Census Bureau examine new methods, processes, and approaches to the census. Its stated purpose is to assess the viability of new or revised design elements for the 2030 Census.
The Big Picture
According to a recent Government Accountability Office (GAO) report published June 4, the Census Bureau initially planned to test new census methods across six locations during the 2026 Census Test. After a review by the Department of Commerce, that number dropped to two: Huntsville, Alabama, and Spartanburg, South Carolina. The reduction eliminated testing opportunities in tribal-lands sites and rural areas, communities that are historically harder to count.
The Department of Commerce narrowed the test's focus to two priorities: piloting in-field enumeration by U.S. Postal Service staff and enhancements to field infrastructure, staffing, and training. This meant scrapping or reducing 10 of 19 operational activities the Census Bureau had originally planned to test, including providing an internet self-response option for residents of university halls, and changing how the Bureau uses administrative data to enumerate certain households.
The Government Accountability Office reviewed operational and staffing plans for both the 2026 test and the 2030 Census, and sought a rationale from the Department of Commerce regarding the scope reduction. In June 2026 the department concurred with the recommendations and stated it would prepare a formal action plan, though specific comprehensive milestones are still being evaluated.
The Bottom Line
By removing testing sites in harder-to-count communities, the Census Bureau loses the opportunity to validate approaches in the very communities where they matter most.
GAO recommended that the Secretary of Commerce instruct the Census Bureau Director to research and test the operational activities and design features removed from the 2026 Census Test prior to finalizing the design of the 2030 Census, and to determine decennial census workforce needs so the Bureau may address skills gaps in time to effectively manage the 2030 Census.
The Department of Commerce has agreed with both recommendations, though both remain open with no actions yet taken or formally planned.
