Pittsburgh is a city in Allegheny County, Pennsylvania, United States, and its county seat. It is the second-most populous city in Pennsylvania (after Philadelphia) and the 67th-most populous city in the U.S., with a population of 302,971 as of the 2020 census. The city is located in southwestern Pennsylvania at the confluence of the Allegheny River and Monongahela River, which combine to form the Ohio River. It anchors the Pittsburgh metropolitan area, which had a population of 2.5 million residents and is the largest metro area in both the Ohio Valley and Appalachia, the second-largest in Pennsylvania, and the 26th-largest in the U.S. Pittsburgh is known as "the Steel City" for its dominant role in the history of the U.S. steel industry. It developed as a vital link of the Atlantic coast and Midwest, as the mineral-rich Allegheny Mountains led to the region being contested by the French and British empires, Virginians, Whiskey Rebels, and Civil War raiders. For part of the 20th century, Pittsburgh was behind only New York City and Chicago in corporate headquarters employment; it had the most U.S. stockholders per capita. Deindustrialization in the late 20th century resulted in massive layoffs among blue-collar workers as steel and other heavy industries declined, coinciding with several Pittsburgh-based corporations moving out of the city. However, the city divested from steel and, since the 1990s, Pittsburgh has focused its energies on the healthcare, education, and technology industries.
