Pennsylvania Information
The Commonwealth of Pennsylvania , often colloquially referred to as PA
(its postal abbreviation, which succeeds the archaic Penn. and Penna. as common abbreviations) by natives and Northeasterners, is a state located
in the Northeastern and Middle Atlantic regions of the United States. The
state borders Delaware and Maryland to the south, West Virginia to the
southwest, Ohio to the west, New York and a water border with Ontario to
the north, and New Jersey to the east. The state's three most populous cities
are, respectively, Philadelphia, Pittsburgh and Allentown. The state capital is Harrisburg.
Pennsylvania has been known as the Keystone State since 1802, based in
part upon its central location among the original Thirteen Colonies forming
the United States, and also in part because of the number of important
American documents signed in the state (such as the Declaration of Independence). It was also a keystone state economically, having both
the industry common to the North (making such wares as Conestoga wagons
and rifles)and the agriculture common to the South (producing feed, fiber,
food, and tobacco)
