Pittsburgh (pronounced /ˈpɪtsbərɡ/) is the second-largest city in the Commonwealth of Pennsylvania and the county seat of Allegheny County. Regionally, it anchors the largest urban area of Appalachia^[7] and the Ohio River Valley, and nationally, it anchors the 22nd largest urban area in the United States.^[8]

The 2009 estimated population of the city was 311,647,^[9] while the seven-county metropolitan area was estimated at 2,354,957.^[10]Downtown Pittsburgh retains substantial economic influence, ranking at 25th in the nation for jobs within the urban core and 6th in job density.^[11]

The characteristic shape of Pittsburgh's central business district is a triangular tract carved by the confluence of the Allegheny andMonongahela rivers, where the Ohio River forms. The city features 151 high-rise buildings,^[12] 446 bridges,^[13] two inclined railways, and a pre-revolutionary fortification. Pittsburgh is known colloquially as "The City of Bridges" and "The Steel City" for its many bridges and former steel manufacturing base.

While the city is historically known for its steel industry, today its economy is largely based on healthcare, education, technology, robotics, and financial services. The region is also becoming a hub for oil and natural gas companies' Marcellus Shale production.^[14][15]The city has redeveloped abandoned industrial sites with new housing, shopping and offices, such as The Waterfront and the SouthSide Works. While Pittsburgh faced an economic crisis in the 1980s as the regional steel industry waned,^[16] modern Pittsburgh is economically strong.^[17] The housing market is relatively stable despite a national subprime mortgage crisis, and Pittsburgh added jobs in 2008 even as the national economy entered a significant jobs recession.^[18] This positive economic trend is in contrast to the 1980s, when Pittsburgh lost its manufacturing base in steel and electronics, and corporate jobs in the oil (Gulf Oil), electronics (Westinghouse), chemical (Koppers) and defense (Rockwell International) industries. The city is also headquarters to major global financial institutionsPNC Financial Services (the nation's fifth largest bank), Federated Investors and the regional headquarters of BNY Mellon, descended from Mellon Financial and the Mellon family.

Major publications often note Pittsburgh's high livability compared to other American cities. Most recently, in 2010, Forbes and Yahoo!both listed Pittsburgh as the most livable city in the United States.^[19][20]
