Alaska statistical areas
From Wikipedia, the free encyclopedia
The U.S. State of Alaska currently has four statistical areas that have been delineated by the Office of Management and Budget (OMB). On July 21, 2023, the OMB delineated two metropolitan statistical areas and two micropolitan statistical areas in Alaska.[1] The most populous of these statistical areas is the Anchorage, AK Metropolitan Statistical Area, centered on the state's largest city of Anchorage.
The Office of Management and Budget (OMB) has designated more than 1,000 statistical areas for the United States and Puerto Rico.[2] 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.
Statistical areas
The OMB defines a core-based statistical area (CBSA) as the county or counties (or county-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 a CBSA based on population into a metropolitan statistical area (MSA) for those with at least 50,000 people or a micropolitan statistical area (μSA) for those with 10,000 to 49,999 people.[2]
The OMB defines a combined statistical area (CSA) as two or more adjacent CBSAs where the employment interchange rate (percent commuting from A to B plus percent commuting from B to A) is at least 15%.[2] A primary statistical area (PSA) includes all CSAs and any CBSA that is not a constituent of a combined statistical area.
