Pennsylvania is the 33rd-largest, the 6th-most populous, and the 9th-most densely populated of the 50 United States. The state's five most populous cities are Philadelphia (1,560,297), Pittsburgh (305,801), Allentown (118,577), Erie (100,671), and Reading (89,893). The state capital, and its ninth-largest city, is Harrisburg. Pennsylvania has 140 miles (225 km) of shoreline along Lake Erie and the Delaware Estuary.
The state takes its name from the Ohio River. The name originated from the Iroquois language word ohi-yo, meaning "great river" or "large creek". Partitioned from the Northwest Territory, the state was admitted to the Union as the 17th state (and the first under the Northwest Ordinance) on March 1, 1803. Ohio is historically known as the "Buckeye State" after its Ohio buckeye trees, and Ohioans are also known as "Buckeyes".
