Pennsylvania, officially the Commonwealth of Pennsylvania, is a U.S. state spanning the Mid-Atlantic, Northeastern, and Appalachian regions of the United States. It borders Delaware to the southeast, Maryland to the south, West Virginia to the southwest, Ohio to the west, Lake Erie and the Canadian province of Ontario to the northwest, New York to the north, and New Jersey to the east.
Pennsylvania is 170 miles (274Â km) north to south and 283 miles (455Â km) east to west. Of a total 46,055 square miles (119,282Â km2), 44,817 square miles (116,075Â km2) are land, 490 square miles (1,269Â km2) are inland waters, and 749 square miles (1,940Â km2) are waters in Lake Erie. It is the 33rd-largest state in the United States. Pennsylvania has 51 miles (82Â km) of coastline along Lake Erie and 57 miles (92Â km) of shoreline along the Delaware Estuary. Of the original Thirteen Colonies, Pennsylvania is the only state that does not border the Atlantic Ocean.
The boundaries of the state are the Mason–Dixon line (39°43′ N) to the south, the Twelve-Mile Circle on the Pennsylvania-Delaware border, the Delaware River to the east, 80°31′ W to the west and the 42° N to the north, except for a short segment on the western end, where a triangle extends north to Lake Erie.
Cities include Philadelphia, Reading, Lebanon and Lancaster in the southeast, Pittsburgh in the southwest, and the tri-cities of Allentown, Bethlehem, and Easton in the central east (known as the Lehigh Valley). The northeast includes the former anthracite coal mining cities of Scranton, Wilkes-Barre, Pittston, Nanticoke, and Hazleton. Erie is located in the northwest. State College serves the central region while Williamsport serves the commonwealth’s north-central region as does Chambersburg in the south-central region, with York, Carlisle, and the state capital Harrisburg on the Susquehanna River in the east-central region of the Commonwealth and Altoona and Johnstown in the west-central region.
The state has five geographical regions, namely the Allegheny Plateau, Ridge and Valley, Atlantic Coastal Plain, Piedmont, and the Erie Plain.
Pennsylvania’s diverse topography also produces a variety of climates, though the entire state experiences cold winters and humid summers. Straddling two major zones, the majority of the state, except for the southeastern corner, has a humid continental climate (Köppen climate classification Dfb). The southern portion of the state has a humid subtropical climate. The largest city, Philadelphia, has a humid subtropical climate (Köppen Cfa).
Summers are generally hot and humid. Moving toward the mountainous interior of the state, the winter climate becomes colder, the number of cloudy days increases, and snowfall amounts are greater. Western areas of the state, particularly locations near Lake Erie, can receive over 100 inches (250Â cm) of snowfall annually, and the entire state receives plentiful precipitation throughout the year. The state may be subject to severe weather from spring through summer into autumn. Tornadoes occur annually in the state, sometimes in large numbers, such as 30 recorded tornadoes in 2011; generally speaking, these tornadoes do not cause significant damage.
Pennsylvania is divided into 67 counties. Counties are further subdivided into municipalities that are either incorporated as cities, boroughs, or townships. One county, Philadelphia County, is coterminous with the city of Philadelphia after it was consolidated in 1854. The most populous county in Pennsylvania is Philadelphia, while the least populous is Cameron (4,547). There are a total of 56 cities in Pennsylvania, which are classified, by population, as either first-, second-, or third-class cities. Philadelphia, Pennsylvania’s largest city, has a population of 1.6 million and is the state’s only first-class city. Pittsburgh (303,000) and Scranton (76,000) are second-class and second-class ‘A’ cities, respectively.
The rest of the cities, like the third and fourth-largest—Allentown (126,000) and Reading (95,000)—to the smallest—Parker with a population of only 820—are third-class cities. First- and second-class cities are governed by a “strong mayor” form of mayor–council government, whereas third-class cities are governed by either a “weak mayor” form of government or a council–manager government. Boroughs are generally smaller than cities, with most Pennsylvania cities having been incorporated as a borough before being incorporated as a city. There are 958 boroughs in Pennsylvania, all of which are governed by the “weak mayor” form of mayor-council government. The largest borough in Pennsylvania is State College (40,501) and the smallest is Centralia.
As of the 2020 U.S. census, Pennsylvania had a population of 13,011,844, up from 12,702,379 in 2010. In 2019, net migration to other states resulted in a decrease of 27,718, and immigration from other countries resulted in an increase of 127,007. Net migration to the Commonwealth was 98,289. Migration of native Pennsylvanians resulted in a decrease of 100,000 people. From 2008 to 2012, 5.8% of the population was foreign-born.

Pennsylvania German is often—even though misleadingly—called "Pennsylvania Dutch". The term Dutch used to mean "German" (including the Netherlands), before the Latin name for them replaced it (but stuck with the Netherlands). When referring to the language spoken by the Pennsylvania Dutch people (Pennsylvania German) it means "German" or "Teutonic" rather than "Netherlander". Germans, in their own language, call themselves "Deutsch", (Pennsylvania German: "Deitsch"). The Pennsylvania German language is a descendant of German, in the West Central German dialect family. It is closest to Palatine German. Pennsylvania German is still very vigorous as a first language among Old Order Amish and Old Order Mennonites (principally in the Lancaster County area), whereas it is almost extinct as an everyday language outside the plain communities, though a few words have passed into English usage.
Of all the colonies, only Rhode Island had religious freedom as secure as in Pennsylvania. Voltaire, writing of William Penn in 1733, observed: “The new sovereign also enacted several wise and wholesome laws for his colony, which have remained invariably the same to this day. The chief is, to ill-treat no person on account of religion, and to consider as brethren all those who believe in one God.” One result of this uncommon freedom was a wide religious diversity, which continues to the present.
Pennsylvania’s population in 2010 was 12,702,379; of these, 6,838,440 (53.8%) were estimated to belong to some sort of organized religion. According to the Association of Religion Data Archives (ARDA) at Pennsylvania State University, the largest religious bodies in Pennsylvania by adherents were the Roman Catholic Church with 3,503,028 adherents, the United Methodist Church with 591,734 members, and the Evangelical Lutheran Church in America with 501,974 members. Since 2014 among the religious population, 73% of the state was Christian per the Pew Research Center. In 2020, the Public Religion Research Institute estimated 68% of the population identified with Christianity. Among all surveys, the Roman Catholic Church remained the single-largest Christian denomination in the state.
Pennsylvania’s 2018 total gross state product (GSP) of $803Â billion ranks the state 6th in the nation. If Pennsylvania were an independent country, its economy would rank as the 19th-largest in the world. On a per-capita basis, Pennsylvania’s 2016 per-capita GSP of $50,665 (in chained 2009 dollars) ranks 22nd among the fifty states.
Geo map of average income by location in Pennsylvania. Data shown is from the 2014 American Community Survey five-year estimate. As of 2016, there were 5,354,964 people in employment in Pennsylvania, with 301,484 total employer establishments. Philadelphia in the southeast corner, Pittsburgh in the southwest corner, Erie in the northwest corner, Scranton-Wilkes-Barre in the northeast corner, and Allentown-Bethlehem-Easton in the east central region are urban manufacturing centers. Much of the Commonwealth is rural; this dichotomy affects state politics as well as the state economy. Philadelphia is home to six Fortune 500 companies, with more located in suburbs like King of Prussia; it is a leader in the financial and insurance industry.
Pittsburgh is home to eight Fortune 500 companies, including U.S. Steel, PPG Industries, and H.J. Heinz. In all, Pennsylvania is home to fifty Fortune 500 companies.

The first nationally chartered bank in the United States, the Bank of North America, was founded in 1781 in Philadelphia. After a series of mergers, the Bank of North America is part of Wells Fargo, which uses national charter 1. Pennsylvania is also the home to the first nationally chartered bank under the 1863 National Banking Act. That year, the Pittsburgh Savings & Trust Company received a national charter and renamed itself the First National Bank of Pittsburgh as part of the National Banking Act. That bank is still in existence today as PNC Financial Services and remains based in Pittsburgh. PNC is the state's largest bank and the sixth-largest in the United States.
The Pennsylvania Department of Agriculture worked with private companies to establish "PA Preferred" as a way to brand agricultural products grown or made in the state to support and promote Pennsylvania products and locally grown food. The financial impact of agriculture in Pennsylvania includes employment of more than 66,800 people employed by the food manufacturing industry; and over $1.7 billion in food product export (in 2011).
Pennsylvania has 500 public school districts, thousands of private schools, publicly funded colleges and universities, and over 100 private institutions of higher education.
In general, under state law, school attendance in Pennsylvania is mandatory for a child from the age of 8 until the age of 17, or until graduation from an accredited high school, whichever is earlier. As of 2005, 83.8% of Pennsylvania residents age 18 to 24 have completed high school. Among residents age 25 and over, 86.7% have graduated from high school. Additionally, 27.5% have gone on to obtain a bachelor's degree or higher. State students consistently do well in standardized testing. In 2007, Pennsylvania ranked 14th in mathematics, 12th in reading, and 10th in writing for 8th grade students.
The Pennsylvania State System of Higher Education (PASSHE) is the public university system of the Commonwealth, with 14 state-owned schools. West Chester University has by far the largest student body of the 14 universities. The Commonwealth System of Higher Education is an organizing body of the four state-related schools in Pennsylvania; these schools (Pennsylvania State University, Lincoln University, the University of Pittsburgh, and Temple University) are independent institutions that receive some state funding. There are also 15 publicly funded two-year community colleges and technical schools that are separate from the PASSHE system. Additionally, there are many private two- and four-year technical schools, colleges, and universities.
