The OMB Bulletin No. 23-01, issued by the Office of Management and Budget on July 21, 2023, provides updated delineations of Core Based Statistical Areas (CBSAs), which include Metropolitan Statistical Areas, Micropolitan Statistical Areas, and Combined Statistical Areas. This bulletin replaces the previous OMB Bulletin No. 20-01 and establishes the latest classifications based on the 2020 Standards. The bulletin informs federal agencies about these delineations for consistent data collection and reporting found in six detailed lists, covering 935 CBSAs across the U.S. and Puerto Rico. The bulletin emphasizes the intended statistical use of these areas, clarifying that they are not designed for non-statistical purposes such as program administration. However, it acknowledges that some legislation may require their application for specific programs. Agencies are cautioned that any modifications to these delineations for non-statistical uses must be carefully considered and publicly commented upon. The updated delineations are available electronically on the OMB website, encouraging federal and state use in aligning statistical activities with current standards.
