The Current Population Survey is a monthly survey of approximately 60,000 U.S. households conducted jointly by the U.S. Census Bureau and the Bureau of Labor Statistics. It is the primary source of the official unemployment rate published on the first Friday of each month. The CPS collects data on employment status, occupation, industry, hours worked, earnings, and other demographic characteristics. It has been conducted since 1940. In 2026, it does not include any questions specifically tracking whether a worker's job duties have been automated by AI, whether a layoff was related to AI adoption, or whether a worker is being displaced by AI. The nine senators' March 6, 2026 letter cited this gap explicitly, arguing the CPS should be expanded with AI-specific supplement questions to allow policymakers to track AI displacement before it shows up as a crisis in unemployment figures.
