List of statistical areas in Colorado

The Office of Management and Budget (OMB) has designated more than 1,000 statistical areas across the United States and Puerto Rico.^[3]

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."^[3] The OMB further divides core-based statistical areas into metropolitan statistical areas (MSAs), which have a population of at least 50,000, and micropolitan statistical areas (μSAs), which have a population of at least 10,000, but fewer than 50,000.^[3]

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%".^[3]

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. Of the 21 statistical areas of Colorado, 12 are PSAs comprising four combined statistical areas, three metropolitan statistical areas, and five micropolitan statistical areas.
