The City of Philadelphia
Philadelphia is the largest city in Pennsylvania and the fifth-most-populous city in the United States.
According to the 2010 U.S. Census, the population of the city proper was 1,526,006. The Greater Philadelphia metropolitan area has a population of 6.1 million and is the country’s fifth-largest metro area. A commercial, educational, and cultural center, Philadelphia was the social and geographical center of the original 13 American colonies. It was a centerpiece of early American history, host to many of the ideas and actions that gave birth to the American Revolution and independence. It was the most populous city of the young United States and served as one of the nation’s many capitals during the Revolutionary War and after. After the ratification of the U.S. Constitution, the city served as the temporary national capital from 1790 to 1800 while Washington, D.C., was under construction.
