The group launched by Elon Musk to cut federal spending in the second Trump administration is targeting some U.S. Census Bureau surveys it claims are “wasteful,” worrying users of federal data who are already concerned about the health of the nation’s statistical infrastructure.

The Department of Government Efficiency said on social media this week that five surveys costing $16.5 million that are conducted by the statistical agency for other federal agencies have been “terminated.” It didn’t specify which ones. The DOGE post said some of the questions on the eliminated surveys asked about alcohol consumption and the frequency of home internet use.

Other surveys are being reviewed “one-by-one,” said Tuesday’s post on DOGE’s X account. The Census Bureau didn’t respond this week to an inquiry seeking comment.

Based on the post, it’s highly possible that the eliminated surveys included the Survey of Inmates in Local Jails, which gathered information on inmates for the Department of Justice, and the Ask U.S. Panel, an internet survey conducted with the Department of Defense, said Beth Jarosz, a senior program director at the Population Reference Bureau, a nonpartisan research organization.

There is a public process for changing government surveys that involves giving notice and seeking public comment, and anything that is canceled without going through that process may be violating the law, Jarosz said.

The Census Bureau asks the public survey questions in order to help Congress and federal agencies implement laws or develop policies, said Terri Ann Lowenthal, a former congressional staffer who consults on census issues.
