Map of the seventeen core-based statistical areas in Colorado

The U.S. state of Colorado has twenty-one statistical areas that have been delineated by the Office of Management and Budget (OMB). 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.

On March 6, 2020, the OMB delineated four combined statistical areas, seven metropolitan statistical areas, and ten micropolitan statistical areas in Colorado.[1] The most populous of these statistical areas is the Denver–Aurora, CO Combined Statistical Area, with a population of 3,623,560 at the 2020 census.[2]

Statistical areas

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]

  1. ^ The OMB defines a core as "a densely settled concentration of population, comprising an Urban Area (of 10,000 or more population) delineated by the Census Bureau, around which a core-based statistical area is delineated."[3]
  2. ^ The OMB defines the employment interchange measure as "the sum of the percentage of workers living in the smaller entity who work in the larger entity plus the percentage of employment in the smaller entity that is accounted for by workers who reside in the larger entity."[3]
  3. ^ This table is initially sorted by the most populous primary statistical area, then by the most populous core-based statistical area, and finally by the most populous county.
