Pennsylvania, officially the **Commonwealth of Pennsylvania**, is a state in the **Northeastern/Mid-Atlantic** United States and one of the original 13 colonies. It is known as the **Keystone State** for its central geographic and historical role among the colonies. It ratified the U.S. Constitution on December 12, 1787, as the **second state**. With a population of approximately **13.06–13.2 million** as of 2025–2026 estimates (5th most populous in the U.S.), it covers about 46,054 square miles (33rd in area) and features 67 counties.
### Geography and Climate
Pennsylvania borders New York to the north, New Jersey to the east (separated by the Delaware River in parts), Delaware and Maryland to the southeast, West Virginia to the southwest, and Ohio to the west. Its diverse landscape includes the **Appalachian Mountains** and Allegheny Plateau in the west/center, the fertile Piedmont and agricultural valleys in the southeast (including Amish Country), the Pocono Mountains in the northeast, and the flat coastal plain near Philadelphia. Major rivers include the Delaware, Susquehanna, Allegheny, and Monongahela (forming the Ohio River). The climate is humid continental—cold, snowy winters (especially in the north and mountains) and warm, humid summers—with four distinct seasons supporting skiing, hiking, farming, and fall foliage.
Major cities (approximate 2026 populations):
- **Philadelphia** — largest (~1.56–1.58 million), historic and cultural powerhouse.
- **Pittsburgh** (~300,000–310,000), known for its tech and healthcare renaissance.
- **Allentown** (~124,000–126,000).
- Others: Reading, Erie, Scranton, Bethlehem, Harrisburg (state capital), and Lancaster.
Much of the population clusters in the southeast (Philadelphia metro) and southwest (Pittsburgh metro), with rural and small-town areas dominating the rest.
### History
Named after William Penn ("Penn's Woods"), the colony was founded in 1681 as a Quaker haven emphasizing religious tolerance and peaceful relations with Native Americans (Lenape, Susquehannock, and others). Philadelphia served as the cradle of American independence: the Declaration of Independence and Constitution were signed there, and it was the early U.S. capital. Key events include the Revolutionary War, the Battle of Gettysburg (Civil War turning point), industrial booms in coal, steel, oil, and railroads, and waves of European immigration. Pennsylvania's motto is **"Virtue, Liberty, and Independence."** It transitioned from an industrial powerhouse to a diversified economy in the late 20th century.
### Culture and Famous For
Pennsylvania blends historic significance, industrial heritage, rural traditions, and urban vibrancy:

- **Outdoors and Recreation** — Pocono Mountains (skiing, resorts), Allegheny National Forest, state parks for hiking/fishing, Hersheypark, and the Appalachian Trail.
- **Other** — Strong arts and music scenes (Philadelphia Orchestra, Pittsburgh cultural institutions), professional sports (Eagles, Steelers, Phillies, Penguins, 76ers), and a reputation for "Pennsylvania nice" mixed with blue-collar grit. State symbols include the mountain laurel (flower) and ruffed grouse (bird).
The culture varies widely: cosmopolitan and diverse in Philly, innovative and resilient in Pittsburgh, traditional and agricultural in central/rural areas.
### Economy
Pennsylvania has a large, diversified economy with strengths in:
- **Manufacturing and Advanced Industries** — Steel (legacy), chemicals, pharmaceuticals, life sciences, robotics/AI (Pittsburgh as a hub), and automotive/aerospace.
- **Energy** — Second-largest U.S. natural gas producer (Marcellus Shale), plus nuclear, coal (declining), and growing renewables.
- **Healthcare, Education, and Services** — Major employers via hospitals, universities (Penn, Pitt, Carnegie Mellon, Penn State), and finance/insurance.
- **Agriculture and Tourism** — Dairy, mushrooms (national leader), poultry, apples; tourism generates billions, boosted by historic sites, outdoors, and events like America250 in 2026.

Growth areas include data centers, AI/cloud computing (e.g., major Amazon investments), and exports. Challenges include an aging workforce, slower population growth (recent gains driven by international migration), rural declines, and infrastructure needs. Unemployment typically hovers near national averages, with steady but modest GSP growth projected.
