Pittsburgh

Pittsburgh is a city in the American state of Pennsylvania. The city was known in the 20th century for its steel industry. However, with the collapse of United States steel industry in the 1980s, the economy of Pittsburgh is now mostly based on healthcare, education, technology, and financial services. It is also the home of the Pittsburgh Steelers football team, who have won the Super Bowl six times, the Pittsburgh Pirates, the Pittsburgh Penguins hockey team, the University of Pittsburgh and Carnegie Mellon University. Pittsburgh is the county seat for Allegheny County. The Allegheny and Monongahela rivers meet in Pittsburgh and form the Ohio River.

Pittsburgh is in western Pennsylvania. It has a population of 302,971 people and a metro population of around 2,400,000 people, making it the largest city in the Ohio Valley and Appalachia the second-largest city in Pennsylvania, and the 28th-biggest in the U.S. Pittsburgh was the most livable city in the United States in 2007. In 2014 Pittsburgh was ranked sixth in the country for polluted cities by the American Lung Association.

The French and Indian War started when George Washington went to Pittsburgh. Later it was a center of the Whiskey Rebellion. The Allegheny Mountains had lots of minerals inside, which led to the area historically argued over by the French, British, Virginians, Whiskey Rebels, and Civil War raiders. For a bit of the 20th century, Pittsburgh was behind only New York City and Chicago by corporate and industrial employment. Deindustrialisation in the late 20th century led to huge layoffs among industrial workers. Since the 1990s, the city has changed its energies on the healthcare, education, and technology areas of industry.

The city is served by the Pittsburgh International Airport.
