As of February 28, 2013, the [[United States]] [[Office of Management and Budget]] (OMB) defined 1,098 [[statistical area]]s for the metropolitan areas of the United States and [[Puerto Rico]].<ref name="OMB_13-01">{{cite web |date=February 28, 2013 |title=OMB Bulletin No. 13-01: Revised Delineations of Metropolitan Statistical Areas, Micropolitan Statistical Areas, and Combined Statistical Areas, and Guidance on Uses of the Delineations of These Areas |url=https://obamawhitehouse.archives.gov/sites/default/files/omb/bulletins/2013/b13-01.pdf |url-status=live |archive-url=https://web.archive.org/web/20170121004708/https://obamawhitehouse.archives.gov/sites/default/files/omb/bulletins/2013/b13-01.pdf |archive-date=January 21, 2017 |access-date=April 2, 2013 |publisher=United States Office of Management and Budget}}</ref> These 1,098 statistical areas comprise 929 [[Core-Based Statistical Area]]s (CBSAs) and 169 [[Combined Statistical Area]]s (CSAs). The 929 Core-Based Statistical Areas are divided into 388 [[Metropolitan Statistical Area]]s (MSAs – 381 for the U.S. and seven for Puerto Rico) and 541 [[Micropolitan Statistical Area]]s (μSAs – 536 for the U.S. and five for Puerto Rico). The 169 Combined Statistical Areas (166 for the U.S. and three for Puerto Rico) each comprise two or more adjacent Core Based Statistical Areas.{{citation needed||date=December 2023}}

The Office of Management and Budget defines a Metropolitan Statistical Area as one or more adjacent [[county (United States)|counties]] or [[county-equivalent|county equivalents]] that have at least one [[List of United States urban areas|urban area]] of at least 50,000 population, plus adjacent territory that has a high degree of economic and [[social integration]] with the core as measured by [[commuting]] ties. The OMB then defines a Combined Statistical Area as consisting of various combinations of adjacent metropolitan and micropolitan statistical areas with economic ties measured by commuting patterns. The Office of Management and Budget further defines a core-based statistical area (CBSA) to be a geographical area that consists of one or more counties (or equivalents) anchored by an urban center of at least 10,000 people plus adjacent counties that are socioeconomically tied to the urban center by commuting.
