Aliquippa is a city in Beaver County in the U.S. state of Pennsylvania, located on the Ohio River in the western portions of the Pittsburgh, PA Metropolitan Statistical Area. The population was 9,438 at the 2010 census.HistoryAliquippa was founded by the merger of three towns: Aliquippa, Woodlawn, and New Sheffield. There is no evidence connecting the Seneca Queen Aliquippa with the location of the borough. This was one of several Indian names selected arbitrarily by the Pittsburgh and Lake Erie Railroad in 1878 for stations along the route. Aliquippa is best known as the location of a productive steel mill that the Jones and Laughlin Steel Company constructed there along the Ohio River beginning in 1905. Employment at the facility sustained a population of 27,023 in 1940. The mill closed during the collapse of the steel industry during the 1980s. This major economic loss alongside suburbanization caused a major population loss through the end of the 20th century. The oldest church within the current boundaries of Aliquippa is Mt. Carmel Presbyterian Church (formerly White Oak Flats Presbyterian Church), established about 1793 in the New Sheffield region on Brodhead Road. Many of the city's businesses have left since the closing of the mill. This has left the city economically depressed, with the crime rate dramatically rising over time.
