Micropolitan statistical area in the context of "Office of Management and Budget"

Combined statistical area (CSA) is a United States Office of Management and Budget (OMB) term for a combination of adjacent metropolitan (MSA) and micropolitan statistical areas (μSA) across the 50 U.S. states and the territory of Puerto Rico that can demonstrate economic or social linkage. CSAs were first designated in 2003. OMB defines a CSA by various combinations of adjacent metropolitan and micropolitan areas with economic ties measured by commuting patterns. CSAs retain their own designations as metropolitan or micropolitan statistical areas in their respective larger combined statistical areas.

The primary distinguishing factor between a CSA and an MSA/μSA is that the social and economic ties between the individual MSAs/μSAs within a CSA are at lower levels than those between the counties within an MSA. CSAs represent multiple metropolitan or micropolitan areas that have an employment interchange of at least 15% (% commuting from A to B plus % commuting from B to A). CSAs often represent regions with overlapping labor and media markets.

A New England city and town area (NECTA) was a geographic and statistical entity defined by the U.S. federal government for use in the six-state New England region of the United States. NECTAs are analogous to metropolitan statistical areas and micropolitan statistical areas and are defined using the same criteria, except that they are defined on the basis of New England towns instead of entire counties. NECTAs are classified as either metropolitan or micropolitan NECTAs. A micropolitan NECTA has an urban core with a population of at least 10,000 but less than 50,000, whereas a metropolitan NECTA has an urban core with a population of at least 50,000. Tabulations of census information by NECTA was discontinued effective July 2023.

In New England, towns (which are classified by the United States Census Bureau as minor civil divisions) are a much more important level of government than counties. Because towns are smaller than counties, a NECTA usually provides a much closer approximation to the real metropolitan area than a metropolitan statistical area does.

The Washington–Baltimore combined metropolitan statistical area is a statistical area, including the overlapping metropolitan areas of Washington, D.C. and Baltimore. The region includes Central Maryland, Northern Virginia, three counties in the Eastern Panhandle of West Virginia, and one county in south-central Pennsylvania. It is the most educated, highest-income, and third-most populous combined statistical area in the United States behind New York City–Newark, NJ and Los Angeles–Long Beach.

The area is designated by the Office of Management and Budget (OMB) as the Washington–Baltimore–Arlington, DC–MD–VA–WV–PA Combined Statistical Area. It is composed primarily of two major metropolitan statistical areas (MSAs), the Washington–Arlington–Alexandria, DC–VA–MD–WV MSA and the Baltimore–Columbia–Towson, Maryland Metropolitan Statistical Area. Five smaller urban areas not contiguous to the main urban area but having strong commuting ties with the main area are included in the metropolitan area:Hagerstown–Martinsburg, Maryland–West Virginia MSA, the Chambersburg–Waynesboro, Pennsylvania MSA, the Winchester, VA–WV MSA, the California–Lexington Park, Maryland MSA, and the Easton, Maryland micropolitan statistical area (μSA).

Minnesota (/ˌmɪnəˈsoʊtə/ MIN-ə-SOH-tə) is a state in the Upper Midwestern region of the United States. It is bordered by the Canadian provinces of Manitoba and Ontario to the north and east and by the U.S. states of Wisconsin to the east, Iowa to the south, and North Dakota and South Dakota to the west. The northeast corner has a water boundary with Michigan. It is the 12th-largest U.S. state in area and the 22nd-most populous, with about 5.8 million residents. Minnesota is known as the "Land of 10,000 Lakes"; it has 14,420 bodies of fresh water covering at least ten acres each. Roughly a third of the state is forested. Much of the remainder is prairie and farmland. More than 60% of Minnesotans (about 3.71 million) live in the Minneapolis–Saint Paul metropolitan area, known as the "Twin Cities", which is Minnesota's main political, economic, and cultural hub and the 16th-largest metropolitan area in the U.S. Other minor metropolitan and micropolitan statistical areas include Duluth, Mankato, Moorhead, Rochester, and St. Cloud.

Minnesota, which derives its name from the Dakota language, has been inhabited by various Native Americans since the Woodland period of the 11th century BCE. Between roughly 200 and 500 CE, two areas of the indigenous Hopewell tradition emerged: the Laurel complex in the north, and Trempealeau Hopewell in the Mississippi River Valley in the south. The Upper Mississippian culture, consisting of the Oneota people and other Siouan speakers, emerged around 1000 CE and lasted through the arrival of Europeans in the 17th century. French explorers and missionaries were the earliest Europeans to enter the region, encountering the Dakota, Ojibwe, and various Anishinaabe tribes. Much of what is now Minnesota formed part of the vast French holding of Louisiana, which the United States purchased in 1803. After several territorial reorganizations, the Minnesota Territory was admitted to the Union as the 32nd state in 1858. Minnesota's official motto, L'Étoile du Nord ("The Star of the North"), is the only state motto in French. This phrase was adopted shortly after statehood and reflects both the state's early French explorers and its position as the northernmost state in the contiguous U.S.

The United States Office of Management and Budget (OMB) has defined 935 core-based statistical areas (CBSAs) for the United States and 10 for Puerto Rico. The OMB defines a core-based statistical area as one or more adjacent counties or county equivalents that have at least one urban core area of at least 10,000 population, plus adjacent territory that has a high degree of social and economic integration with the core as measured by commuting ties. The 935 core-based statistical areas currently defined by the OMB include the 393 metropolitan statistical areas (MSAs), which have an urban core population of at least 50,000, and the 542 micropolitan statistical areas (μSAs), which have an urban core population of at least 10,000 but less than 50,000.

The United States federal government defines and delineates the nation's metropolitan areas for statistical purposes, using a set of standard statistical area definitions. As of 2023, the U.S. Office of Management and Budget (OMB) defined and delineated 393 metropolitan statistical areas (MSAs) and 542 micropolitan statistical areas (μSAs) in the United States and Puerto Rico. Many of these 935 MSAs and μSAs are, in turn, components of larger combined statistical areas (CSAs) consisting of adjacent MSAs and μSAs that are linked by commuting ties; as of 2023, 582 metropolitan and micropolitan areas are components of the 184 defined CSAs.

Metropolitan and micropolitan statistical areas are defined as consisting of one or more adjacent counties or county equivalents with at least one urban core area meeting relevant population thresholds, plus adjacent territory that has a high degree of social and economic integration with the core, as measured by commuting ties. A metropolitan statistical area has at least one core with a population of at least 50,000. In a micropolitan statistical area, the largest core has a population of at least 10,000 but less than 50,000.
