The Trump administration is eliminating four out of the six locations that had been slated for a practice test to try out new methods for the 2030 census, raising concerns that the U.S. Census Bureau might not learn enough about communities that have been traditionally difficult to count.
The test, which started Monday, will be conducted only in Huntsville, Alabama, and Spartanburg, South Carolina, according to a notice submitted by the Commerce Department that will be formally published on Tuesday. The Commerce Department oversees the Census Bureau.
Four other sites — Colorado Springs, Colorado, tribal lands in Arizona, western North Carolina and western Texas — originally were included when the Census Bureau announced the locations in 2024.
The bureau didn't respond to an emailed inquiry on Monday about the reasons for the reduced number of sites. In a statement on its website, it said it ''remains committed to conducting the most accurate count in history for the 2030 Census and looks forward to the continued partnership with local communities.''
Mark Mather, an associate vice president at the Population Reference Bureau, a nonpartisan research group, said limiting the test to just two metro areas in the South would be ''a step backward.''
''The Census Bureau would be essentially flying blind into communities that need testing most — tribal lands, rural areas with limited connectivity and places with historically low response rates,'' Mather said. ''You can't fix what you don't test.''
Terri Ann Lowenthal, a former congressional staffer who consults on census issues, called the locale eliminations ''an ominous sign for the 2030 Census.''
''The new plan for 2026 is unclear,'' Lowenthal said.
