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 in Western Pennsylvania, Eastern Ohio, Northern West Virginia, and Western Maryland. By this definition, the informal regional boundaries are similar to historical interpretations where the region is defined as the central portion of the Allegheny Plateau to the west and north of the Allegheny Front and south of Lake Erie and Pennsylvania's Northern Tier. The hills and river valleys along the Upper Ohio River and its many eastern tributaries, including the Allegheny and Monongahela rivers have historically been the major centers of population of the region.
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-eight Pennsylvania 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, and Westmoreland), nineteen West Virginia counties (Barbour, Brooke, Doddridge, Grant, Hancock, Harrison, Lewis, Marion, Marshall, Mineral, Monongalia, Ohio, Preston, Randolph, Taylor, Tucker, Tyler, Upshur, and Wetzel), five Ohio counties (Belmont, Columbiana, Harrison, Jefferson, and Monroe), and two Maryland counties (Allegany and Garrett), and portions of Chautauqua, New York in and around Ripley. The combined population of the megaregion was over 4.9 million in 2016.

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

Economy
Historically, Pittsburgh has been grouped in the "Rust Belt"; 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.
Pittsburgh's association with the Great Lakes region is due in part to its economic, demographic and commuter connections to Great Lakes cities like Cleveland, Erie, Toledo and even Detroit. Christopher Briem, an economist at the University 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 as Youngstown, Akron, and Cleveland, not to Pennsylvanian cities such as Allentown, Scranton, or Philadelphia. He notes that, conversely, the population centers of northeastern Ohio are primarily connected with Pittsburgh and only secondarily connected to the state capital of Columbus. Briem argues that "In so many ways the state boundaries we think of as important are no more than lines on a map." 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 of I-76 between the cities. Robert Lang and Arthur Nelson of the Metropolitan Institute at Virginia Tech also identify the region between Cleveland and Pittsburgh as being an interconnected "megapolitan area" and refer to it as the "Steel Corridor".

The largest school district in the area is the Pittsburgh Public Schools, with the school districts of Allegheny County also boasting large student bodies. Many private schools also serve the core county of Allegheny. More public districts are found throughout Beaver, Westmoreland, and Washington counties, and private schools in each county.
Several area colleges and universities serve the region. Pittsburgh itself is home to many colleges, universities, and research facilities, the most well-known of which are Carnegie Mellon University, the University of Pittsburgh, and Duquesne University. Also in the city are Carlow University, Chatham University, Point Park University, the Community College of Allegheny County, Pittsburgh Theological Seminary, Reformed Presbyterian Theological Seminary, and the Pittsburgh Institute of Mortuary Science. Within the greater metropolitan area, universities include Clarion University of Pennsylvania, La Roche University, Slippery Rock University, Westminster College and Grove City College north of the city, Robert Morris University and Geneva College west of the city, Washington & Jefferson College, Pennsylvania Western University and Waynesburg University to the south, and Seton Hill University, Saint Vincent College, Westmoreland County Community College and Indiana University of Pennsylvania to the east.
Transportation
Airports
Pittsburgh International Airport (IATA: PIT) is located 17 mi (27 km) to the west of downtown Pittsburgh in Findlay. The smaller but less crowded Arnold Palmer Regional Airport (IATA: LBE) to the east of downtown in Latrobe provides commercial service to the metro area.
Pittsburgh International was the fortress hub of US 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. In 2007, US Airways did select the airport for its new $25 million, 27,000 sq ft (2,500 m), 600-employees-strong Global Flight Operations Center. Since being de-hubbed the airport has seen expanded service from JetBlue, Southwest Airlines and Delta Air Lines' direct trans-Atlantic service to Paris.
Arnold Palmer Regional Airport offers commercial service via Spirit Airlines to Florida and South Carolina. Palmer has had commercially scheduled air service since the 1980s.
Allegheny County Airport (IATA: AGC) in suburban West Mifflin, Pennsylvania, is the area's largest general aviation airport. The historic landmark, art deco terminal was the main passenger airport for the area until 1952. Allegheny opened in 1931 as the nation's third-largest and first with "hard surface" runways.
Smaller suburban airports serve as private plane and corporate jet bases include:
- North Metro:
- South Metro:
- East Metro:

Culture
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 of Appalachia as defined by the Appalachian Regional Commission. The City of Pittsburgh has been characterized as the "northern urban industrial anchor of Appalachia" which makes it an anomaly compared to much of Appalachia which has traditionally been characterized as southern, rural, and economically distressed.
Joseph Scarpaci, professor emeritus of geography at Virginia Tech, has described Pittsburgh as having "one foot in the East...and the other in the Midwest". Barbara Johnstone, professor of rhetoric and linguistics at Carnegie Mellon University, ascribes this isolation and idiosyncratic cultural identity of the region to the difficulty of moving through the Allegheny Mountains and the Allegheny 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.
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.
Arts
Visual arts
Greater Pittsburgh is home to several museums, galleries, and organizations which promote appreciation for the visual arts.

Sports and recreation
Main article: Sports in Pittsburgh
The Pittsburgh area served as a launchpad for the professionalization of both American football and ice 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 (the Latrobe Athletic Association), and a participant in the first all-professional league (the Pittsburgh Stars of the first National Football League). In the case of ice hockey, the Western Pennsylvania Hockey League was the first hockey league to pay its players in 1901, eventually merging into the first fully pro league, the International 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.
Golf
Golf in the metro area boasts such courses as Oakmont Country Club, which has hosted the U.S. Open a record nine times, and Foxburg Country Club the oldest continuous club in the U.S. Such tournaments as the 84 Lumber Classic, Pittsburgh Senior Open and the current Mylan Classic call the region home. Area courses have also hosted multiple PGA Championships, LPGA Championships, U.S. Women's Opens and Ryder Cup matches.
Annual sports events
Annual sporting events include the Head of the Ohio crew race, Three Rivers Regatta, Pittsburgh Vintage Grand Prix, and the Pittsburgh Marathon.
The regions rivers have hosted the Bassmaster Classic and Forrest Wood Cup and the city has enjoyed having one of only two teams to host the Major League Baseball All Star Game a record eight times. The area has also hosted the NHL All Star Game, NHL Winter Classic, Senior Olympics, NHL Entry Draft, AHL All Star Game, NCAA Tournament and Frozen Four.
Winter in the region sees sport continue at such rinks at PPG Place and North Park as well as area ski resorts like Boyce Park, Seven Springs Mountain Resort, Hidden Valley, Laurel Mountain and Wisp.
