Erie/ˈɪəri/ is a city in northwestern Pennsylvania, United States. Named for the lake and the Native American tribe that resided along its southern shore, Erie is the state's fourth-largest city (after Philadelphia, Pittsburgh and Allentown), with a population of 101,786 at the 2010 census, and an estimated population of 99,452 in 2014. It was the third-largest city in the state until 1999. It is the second largest city in Western Pennsylvania (after Pittsburgh) and the largest city in northwestern Pennsylvania. Erie's metropolitan area, equivalent to all of Erie County, consists of approximately 280,000 residents. The city is the seat of government for Erie County and the principal city of the Erie, PA Metropolitan Statistical Area.
Erie is between Buffalo, New York, Cleveland, Ohio, and Pittsburgh, Pennsylvania. Once teeming with heavy industry, Erie's manufacturing sector remains prominent in the local economy, though service industries, health care, higher education, and tourism are emerging as greater economic drivers. Hundreds of thousands visit Erie for recreation at Presque Isle State Park, as well as attractions like the casino and horse racetrack named for the state park.
Erie is known as the "Flagship City" because of its status as the home port of Oliver Hazard Perry's flagship Niagara. The city has also been called the "Gem City" because of the sparkling lake. Erie won the All-America City Award in 1972.
