TheU.S.State of Wisconsin currently has 40statistical areas that have been delineated by theOffice of Management and Budget (OMB). On July 21, 2023, the OMB delineated 11combined statistical areas, 15metropolitan statistical areas, and 14micropolitan statistical areas in Wisconsin.[1] As of 2023, the largest of these is theMilwaukee-Racine-Waukesha, WI CSA, comprising the area around Wisconsin's largest city,Milwaukee.
TheOffice of Management and Budget (OMB) has designated more than 1,000statistical areas for theUnited States andPuerto Rico.[2] These statistical areas are important geographic delineations of population clusters used by the OMB, theUnited States Census Bureau, planning organizations, and federal, state, and local government entities.
The OMB defines acore-based statistical area (commonly referred to as aCBSA) as thecounty or counties (orcounty-equivalents) surrounding at least one densely-settled core of at least 10,000 population,[2] "plus adjacent counties having a high degree of social and economic integration with the core as measured through commuting ties with the counties containing the core".[2] The OMB further divides core-based statistical areas based on population intometropolitan statistical areas (MSAs) for those with at least 50,000 andmicropolitan statistical areas (μSAs) for those with 10,000 to 49,999 people.[2]
The OMB defines acombined statistical area (CSA) as two or more adjacentcore-based statistical areas where the employment interchange rate (% commuting from A to B plus % commuting from B to A) is at least 15%.[2] Theprimary statistical areas (PSAs) include allcombined statistical areas and anycore-based statistical area that is not a constituent of a combined statistical area.
The following table provides the in-state population ranking of each CBSA along with its rate of population change over time.
