The Pittsburgh metropolitan area (also called Greater Pittsburgh, Southwestern Pennsylvania or the Pittsburgh Tri-State) is the largest population center in both the Ohio River Valley and Appalachia. The metropolitan area consists of the city of Pittsburgh in the Commonwealth of Pennsylvania and surrounding counties. By many definitions the area extends into the U.S. states of West Virginia and Ohio.〔(【引用サイトリンク】title=Explore by Map )〕 The larger "tri-state" region is defined by the U.S. Census as the Combined Statistical Area (CSA) while definitions of the Metropolitan Statistical Area (MSA) are within Pennsylvania.〔http://www.whitehouse.gov/sites/default/files/omb/bulletins/2013/b13-01.pdf〕 The area is renowned for its industries including steel, glass and oil; its economy also thrives on healthcare, education, technology, robotics, financial services and the film industry. The region is an emergent area for oil and natural gas companies' Marcellus shale production. The city is headquarters to major global financial institutions including PNC Financial Services (the nation's fifth-largest bank), Federated Investors and the regional headquarters of BNY Mellon. The region is also the 21st largest port in the United States with almost 34 million short tons of river cargo for 2011, the port ranked 9th largest in the U.S. when measured in domestic trade.〔http://aapa.files.cms-plus.com/PDFs/2011%20U%20S%20%20PORT%20RANKINGS%20BY%20CARGO%20TONNAGE.pdf〕 Since 1954 suburban Boyers, Pennsylvania has been home to one of the world's largest archives including CORBIS images, and Federal documents, since 1998 Iron Mountain Incorporated has used the complex as its main facility. thumb ==Definition== The U.S. Census Bureau defines the area as both an MSA consisting of seven Western Pennsylvania counties anchored by the city of Pittsburgh and a twelve county Pittsburgh–New Castle-Weirton CSA with 2 West Virginia counties and one in Ohio. The MSA definition includes the city proper and the Pennsylvania counties of Allegheny, Armstrong, Beaver, Butler, Fayette, Washington, and Westmoreland. The CSA definition also adds the two Western Pennsylvania counties of Lawrence and Indiana, West Virginia's Brooke and Hancock as well as Ohio's Jefferson. The MSA had a 2012 population of 2,360,733〔http://www.census.gov/popest/data/metro/totals/2012/tables/CBSA-EST2012-01.csv〕 and has a land area of 5,343 sq. miles, while the CSA had a 2012 population of 2,661,369.〔http://www.census.gov/popest/data/metro/totals/2012/tables/CBSA-EST2012-02.csv〕 Pittsburgh is part of the Great Lakes Megalopolis containing an estimated 54 million people, while many residents also consider themselves part of the Mid-Atlantic coastal region of Virginia to New York. It is classified as Northeast by the U.S. Census with the West Virginia and Ohio components of the CSA being classified as South and Mid-west respectively.〔()〕 The entire MSA and CSA are within the Congressional Appalachian Regional Commission's definition of Appalachia. The area's media market extends to 15 counties in Pennsylvania, Maryland and West Virginia. The region is also sometimes defined as reaching into the southwestern New York State county of Chautauqua the western Maryland counties of Garrett and Allegany as well as the majority of West Virginia, all of Western Pennsylvania and the east-central counties of Ohio.〔(【引用サイトリンク】title=District Map )〕〔(【引用サイトリンク】title=County Warning Forecast Area WFOs )〕〔(【引用サイトリンク】title=United States Military Entrance Processing Command )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Pittsburgh metropolitan area」の詳細全文を読む スポンサード リンク
