Metropolitan statistical area
In theUnited States,ametropolitan statistical area(MSA) is ageographical regionwith a relatively highpopulation densityat itscoreand close economic ties throughout the region.[1][2]Such regions are not legallyincorporated as a city or town would beand are not legaladministrative divisionslikecountiesor separate entities such asstates.As a result, sometimes the precise definition of a givenmetropolitan areawill vary between sources. The statistical criteria for a standard metropolitan area were defined in 1949 and redefined as a metropolitan statistical area in 1983.[3]
Due to suburbanization, the typical metropolitan area is polycentric rather than being centered around a large historic core city such asNew York CityorChicago.[4]Some metropolitan areas include more than one large historic core city; examples include theDallas–Fort Worth metroplex,Virginia Beach–Norfolk–Newport News (Hampton Roads),Riverside–San Bernardino (Inland Empire),andMinneapolis–Saint Paul (Twin Cities).
MSAs are defined by theOffice of Management and Budget(OMB), which is part of theExecutive Office of the President,and are used by theU.S. Census Bureauand otherU.S. federal governmentagencies for statistical purposes.[5]
Definitions
editThe U.S.Office of Management and Budgetdefines a set ofcore based statistical areas(CBSAs) throughout the country, which are composed ofcounties and county equivalents.[7]
CBSAs are delineated on the basis of a central contiguous area of relatively high population density, known as anurban area.The counties containing the core urban area are known as the "central counties" of the CBSA; these are defined as having at least 50% of their population living inurban areasof at least 10,000 in population.[8]Additional surrounding counties, known as "outlying counties", can be included in the CBSA if these counties have strong social and economic ties to the central county or counties as measured bycommutingand employment. Outlying counties are included in the CBSA if 25% of the workers living in the county work in the central county or counties, or if 25% of the employment in the county is held by workers who live in the central county or counties.
Adjacent CBSAs are merged into a single CBSA when the central county or counties of one CBSA qualify as an outlying county or counties to the other CBSAs.[8]One or more CBSAs may be grouped together or combined to form a larger statistical entity known as acombined statistical area(CSA) when the employment interchange measure (EIM) reaches 15% or more.
CBSAs are subdivided into MSAs (formed around urban areas of at least 50,000 in population) andmicropolitan statistical areas(μSAs), which are CBSAs built around an urban area of at least 10,000 in population but less than 50,000 in population. Some metropolitan areas may include multiple cities below 50,000 people, but combined have over 50,000 people.[8]Previous terms that are no longer used to describe these regions include "standard metropolitan statistical area" (SMSA) and "primary metropolitan statistical area" (PMSA).[9]
On January 19, 2021, OMB submitted a regulation for public comment that would increase the minimum population needed for an urban area population to be a metropolitan statistical area to be increased from 50,000 to 100,000.[10]It ultimately decided to keep the minimum at 50,000 for the 2020 cycle.[11]
On July 21, 2023, theOffice of Management and Budgetreleased revised delineations of the various CBSAs in the United States.[6]
History
editThe Census Bureau created the metropolitan district for the1910 censusas a standardized classification for large urban centers and their surrounding areas. The original threshold for a metropolitan district was 200,000, but was lowered to 100,000 in 1930 and 50,000 in 1940.[12]The metropolitan districts were replaced by standard metropolitan areas (SMAs) in the1950 census,which were defined by the Bureau of the Budget (now the Office of Management and Budget) and later renamed to standard metropolitan statistical areas (SMAs) in 1959.[12][13]The modern metropolitan statistical area was created in 1983 amid a large increase in the number of eligible markets, which grew from 172 in 1950 to 288 in 1980;[12][14]the core based statistical area (CBSA) was introduced in 2000 and defined in 2003 with a minimum population of 10,000 required for micropolitan areas and 50,000 for urban areas.[12][13]
