Map of the 22 core-based statistical areas in Washington (state).
An enlargeable map of the 22 core-based statistical areas in Washington. [1]

The U.S. state of Washington has 28 statistical areas that have been delineated by the Office of Management and Budget (OMB). On March 6, 2020, the OMB delineated six combined statistical areas, 13 metropolitan statistical areas, and nine micropolitan statistical areas in Washington. [1] The largest of them is the Seattle metropolitan area, which had a population of 4,018,762 as of the 2020 census. [2]

The state historically had three metropolitan areas: Seattle, Spokane, and Tacoma. Seattle and Tacoma were eventually merged, while other metropolitan areas were added in the 1970s and 1980s. [3]

Statistical areas

The Office of Management and Budget (OMB) has designated more than 1,000 statistical areas for the United States and Puerto Rico. [4] These statistical areas are important geographic delineations of population clusters used by the OMB, the United States Census Bureau, planning organizations, and federal, state, and local government entities.

The OMB defines a core-based statistical area (commonly referred to as a CBSA) as "a statistical geographic entity consisting of the county or counties (or county-equivalents) associated with at least one core [a] of at least 10,000 population, 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." [4] The OMB further divides core-based statistical areas into metropolitan statistical areas (MSAs) that have "a population of at least 50,000" and micropolitan statistical areas (μSAs) that have "a population of at least 10,000, but less than 50,000." [4]

The OMB defines a combined statistical area (CSA) as "a geographic entity consisting of two or more adjacent core-based statistical areas with employment interchange measures [b] of at least 15%." [4] The primary statistical areas (PSAs) include all combined statistical areas and any core-based statistical area that is not a constituent of a combined statistical area.
