Garrett Nelson and Alasdair Rae's 2016 analysis of American commuter flows, "An Economic Geography of the United States: From Commutes to Megaregions", identified the Pittsburgh megaregion as a region encompassing the entirety or significant portions of 54 counties inWestern Pennsylvania, EasternOhio, NorthernWest Virginia, and WesternMaryland.[11] By this definition, the informal regional boundaries are similar to historical interpretations where the region is defined as the central portion of theAllegheny Plateau to the west and north of theAllegheny Front and south ofLake Erie and Pennsylvania'sNorthern Tier.[12] The hills and river valleys along the UpperOhio River and its many eastern tributaries, including theAllegheny andMonongahela rivers have historically been the major centers of population of the region.[12]
According to this research the US can be divided into 'mega regions' based on the most extreme commuting patterns within a geographical area (commutes within 100 miles from the core city). By this liberal definition, the Pittsburgh mega region consists of twenty-eightPennsylvania counties (Allegheny,Armstrong,Beaver,Bedford,Blair,Butler,Cambria,Cameron,Centre,Clarion,Clearfield,Crawford,Elk,Erie,Fayette,Forest,Greene,Huntingdon,Indiana,Jefferson,Lawrence,Mercer,Mifflin,Somerset,Venango,Warren,Washington, andWestmoreland), nineteenWest Virginia counties (Barbour,Brooke,Doddridge,Grant,Hancock,Harrison,Lewis,Marion,Marshall,Mineral,Monongalia,Ohio,Preston,Randolph,Taylor,Tucker,Tyler,Upshur, andWetzel), fiveOhio counties (Belmont,Columbiana,Harrison,Jefferson, andMonroe), and twoMaryland counties (Allegany andGarrett), and portions ofChautauqua, New York in and aroundRipley.[11] The combined population of the megaregion was over 4.9 million in 2016.[13]

There are also several formal definitions of Greater Pittsburgh which are often used in media mentions of the region. These include theOffice of Management and Budget's Pittsburgh, PA Metropolitan Statistical Area (MSA) andPittsburgh-New Castle-Weirton, PA-OH-WV Combined Statistical Area (CSA).[15] TheNielsen Corporation'sPittsburgh Designated Market Area (DMA) is another commonly used formal definition of the region.[16] There are nineteen counties included in at least one of these definitions and their combined population was over 2.9 million in 2016.[13]

Historically, Pittsburgh has been grouped in the "Rust Belt";[17] however, reflective of the rebound of the region within the last generation, the metro area has been included as a part of the "Great Lakes Basin" gaining representation in the Great Lakes Metro Chamber Coalition.[18][19]
Pittsburgh's association with theGreat Lakes region is due in part to its economic, demographic and commuter connections to Great Lakes cities likeCleveland,Erie,Toledo and evenDetroit.[20] Christopher Briem, an economist at theUniversity of Pittsburgh's University Center for Social and Urban Research, has argued that southwestern Pennsylvania is "far more interconnected" with northeastern Ohio than it is with the eastern half of Pennsylvania, and that the industries of Pittsburgh are primarily linked to Ohioan cities such asYoungstown,Akron, andCleveland, not to Pennsylvanian cities such asAllentown,Scranton, orPhiladelphia.[21] He notes that, conversely, the population centers of northeastern Ohio are primarily connected with Pittsburgh and only secondarily connected to the state capital ofColumbus. Briem argues that "In so many ways the state boundaries we think of as important are no more than lines on a map."[21] In recognizing their economic interdependence, Briem coined the term "Cleveburgh" to refer collectively to the cities of Cleveland and Pittsburgh, along with the smaller towns dotting the corridor ofI-76 between the cities.[21][22][23] Robert Lang and Arthur Nelson of the Metropolitan Institute atVirginia Tech also identify the region between Cleveland and Pittsburgh as being an interconnected "megapolitan area" and refer to it as the "Steel Corridor".[24]

Pittsburgh International was thefortress hub ofUS Airways from 1952 to 2005 with over 500 daily departures to more than 110 destinations in 2000. By 2007, fewer than 70 departures to 21 destinations remained.[26] In 2007, US Airways did select the airport for its new $25 million, 27,000 sq ft (2,500 m2), 600-employees-strongGlobal Flight Operations Center. Since being de-hubbed the airport has seen expanded service fromJetBlue,Southwest Airlines andDelta Air Lines' direct trans-Atlantic service to Paris.

Pittsburgh and its surrounding area has a distinct regional identity and has historically been regarded as a transitional region within the Northeastern United States. The region's counties also fall within the borders ofAppalachia as defined by theAppalachian Regional Commission.[29] The City ofPittsburgh has been characterized as the "northern urban industrial anchor of Appalachia"[30]: which makes it an anomaly compared to much of Appalachia which has traditionally been characterized as southern, rural, and economically distressed.[30]
Joseph Scarpaci,professor emeritus of geography atVirginia Tech,[31] has described Pittsburgh as having "one foot in the East...and the other in the Midwest".[30]Barbara Johnstone, professor of rhetoric and linguistics atCarnegie Mellon University, ascribes this isolation and idiosyncratic cultural identity of the region to the difficulty of moving through theAllegheny Mountains and theAllegheny Plateau.
The Pittsburgh area was sort of isolated. It was very hard to get back and forth across the mountains. There's always been a sense that Pittsburgh was kind of a place unto itself—not really southern, not really Midwestern, not really part of Pennsylvania. People just didn't move very much.[32]
In his 2009 book,The Paris of Appalachia,Pittsburgh Post-Gazette writer Brian O'Neill meditates on this aspect of Pittsburgh's regional and cultural ambiguity. The title of the book is intentionally provocative:
"The Paris of Appalachia" some have called Pittsburgh derisively, because it's still the largest city along this gorgeous mountain chain that needs a better press agent. I've long felt we should embrace that title, though few are with me. Several tried to talk me out of slapping it on the cover, but were we called "The Paris of the Rockies," we wouldn't run from it. Sometimes we're so afraid of what others think, we're afraid to say who we are. This city is not Midwestern. It's not East Coast. It's just Pittsburgh, and there's no place like it. That's both its blessing and its curse.[33]
Greater Pittsburgh is home to several museums, galleries, and organizations which promote appreciation for the visual arts. The largest art museum in the region is theCarnegie Museum of Art, founded in 1895 by industrialistAndrew Carnegie and located in Pittsburgh'sOakland neighborhood.

Other regional visual arts museums include:[37][38]

The Pittsburgh area served as a launchpad for the professionalization of bothAmerican football andice hockey in the 1890s and 1900s. The first professional player (William Heffelfinger) played for a Pittsburgh football team in 1892, which was followed by the first open professional (John Brallier), the first all-professional team (theLatrobe Athletic Association), and a participant in the first all-professional league (thePittsburgh Stars of thefirst National Football League). In the case of ice hockey, theWestern Pennsylvania Hockey League was the first hockey league to pay its players in 1901, eventually merging into the first fully pro league, theInternational Professional Hockey League, in 1904. Professional hockey in Pennsylvania predated the professionalization of the game in Canada (where it eventually came to dominate in the early 20th century) by four years.
Today, the region is home to three major league franchises in baseball, football, and hockey; several minor league teams in soccer, baseball, and hockey; and three major NCAA universities.
