Philadelphia, Pennsylvania, United States

🇺🇸 Philadelphia, is the largest city in the U.S. state of Pennsylvania, and the sixth-most populous U.S. city. The city forms the urban core of the eighth-largest U.S. metropolitan statistical area, with over 6 million residents in the larger metropolitan area. Philadelphia is also the economic and cultural anchor of the greater Delaware Valley, within the Northeast megalopolis. The Delaware Valley is the ninth-largest combined statistical area in the United States.

Philadelphia is one of the oldest municipalities in the United States. William Penn, an English Quaker, founded the city in 1682 to serve as capital of the Pennsylvania Colony. In the 19th and 20th centuries, Philadelphia became a major industrial centre and a railroad hub. The city grew due to an influx of European immigrants, most of whom initially came from Ireland and Germany—the two largest reported ancestry groups in the city. Later immigrant groups in the 20th century came from Italy and other Southern European and Eastern European countries. In the early 20th century, Philadelphia became a prime destination for African Americans during the Great Migration after the Civil War. Puerto Ricans began moving to the city in large numbers in the period between World War I and II, and in even greater numbers in the post-war period.

The Philadelphia area's many universities and colleges make it a top study destination, as the city has evolved into an educational and economic hub. As of 2019, the Philadelphia metropolitan area is estimated to produce a gross metropolitan product (GMP) of $490 billion. Philadelphia is the centre of economic activity in Pennsylvania and is home to five Fortune 1000 companies. The Philadelphia skyline is expanding, with a market of almost 81,900 commercial properties in 2016, including several nationally prominent skyscrapers. Philadelphia has more outdoor sculptures and murals than any other American city. Fairmount Park, when combined with the adjacent Wissahickon Valley Park in the same watershed, is one of the largest contiguous urban park areas in the United States. The city is known for its arts, culture, cuisine, and colonial history, attracting 42 million domestic tourists in 2016 who spent $6.8 billion, generating an estimated $11 billion in total economic impact in the city and surrounding four counties of Pennsylvania. Philadelphia has also emerged as a biotechnology hub.

Philadelphia contains 67 National Historic Landmarks and the World Heritage Site of Independence Hall. The city became a member of the Organization of World Heritage Cities in 2015, as the first World Heritage City in the United States.

Philadelphia's economic sectors include financial services, health care, biotechnology, information technology, trade and transportation, manufacturing, oil refining, food processing, and tourism. Financial activities account for the largest economic sector of the metropolitan area, which is also one of the largest health education and research centres in the United States. Sectors with the largest number of jobs added were in education and health care, leisure and hospitality, and professional and business services. The city's two largest employers are the federal and city governments. Philadelphia's largest private employer is the University of Pennsylvania followed by the Children's Hospital of Philadelphia.

Geography: Topography Philadelphia's geographic centre is about 40° 0′ 34″ north latitude and 75° 8′ 0″ west longitude. The 40th parallel north passes through neighborhoods in Northeast Philadelphia, North Philadelphia, and West Philadelphia including Fairmount Park. The city encompasses 142.71 square miles (369.62 km²), of which 134.18 square miles (347.52 km²) is land and 8.53 square miles (22.09 km²), or 6%, is water. Natural bodies of water include the Delaware and Schuylkill rivers, lakes in Franklin Delano Roosevelt Park, and Cobbs, Wissahickon, and Pennypack creeks. The largest artificial body of water is East Park Reservoir in Fairmount Park.

The lowest point is sea level and the highest point is in Chestnut Hill, about 446 feet (136 m) above sea level on Summit Street near the intersection of Germantown Avenue and Bethlehem Pike at: 40.07815 N, 75.20747 W. Philadelphia is located on the Atlantic Seaboard Fall Line that separates the Atlantic Plain from the Piedmont. The Schuylkill River's rapids at East Falls were inundated by completion of the dam at Fairmount Water Works.

The city is the seat of its own county. The city is bordered by six adjacent counties: Montgomery to the northwest; Bucks to the north and northeast; Burlington County, New Jersey to the east; Camden County, New Jersey to the southeast; Gloucester County, New Jersey to the south; and Delaware County to the southwest.

City planning Philadelphia was created in the 17th century, following the plan by William Penn's surveyor Thomas Holme. Center City is structured with long, straight streets running nearly due east–west and north–south, forming a grid pattern between the Delaware and Schuylkill rivers that is aligned with their courses. The original city plan was designed to allow for easy travel and to keep residences separated by open space that would help prevent the spread of fire. In keeping with the idea of a "Greene Countrie Towne", and inspired by the many types of trees that grew in the region, Penn named many of the east–west streets for local trees. Penn planned the creation of five public parks in the city which were renamed in 1824. Centre Square was renamed Penn Square; Northeast Square was renamed Franklin Square; Southeast Square was renamed Washington Square; Southwest Square was renamed Rittenhouse Square; and Northwest Square was renamed Logan Circle/Square. Center City had an estimated 183,240 residents as of 2015, making it the second-most populated downtown area in the United States after Midtown Manhattan in New York City.

Philadelphia's neighborhoods are divided into six large sections that surround Center City: North Philadelphia, Northeast Philadelphia, South Philadelphia, Southwest Philadelphia, West Philadelphia, and Northwest Philadelphia. The city's geographic boundaries have been largely unchanged since these neighborhoods were consolidated in 1854. However, each of these large areas contains numerous neighborhoods, some of whose boundaries derive from the boroughs, townships, and other communities that constituted Pennsylvania County before their inclusion within the city.

The City Planning Commission, tasked with guiding growth and development of the city, has divided the city into 18 planning districts as part of the Philadelphia2035 physical development plan. Much of the city's 1980 zoning code was overhauled from 2007 to 2012 as part of a joint effort between former mayors John F. Street and Michael Nutter. The zoning changes were intended to rectify incorrect zoning maps to facilitate future community development, as the city forecasts an additional 100,000 residents and 40,000 jobs will be added by 2035.

The Philadelphia Housing Authority (PHA) is the largest landlord in Pennsylvania. Established in 1937, the PHA is the nation's fourth-largest housing authority, serving about 81,000 people with affordable housing, while employing 1,400 on a budget of $371 million. The Philadelphia Parking Authority is responsible for ensuring adequate parking for city residents, businesses, and visitors.

Architecture Philadelphia's architectural history dates back to colonial times and includes a wide range of styles. The earliest structures were constructed with logs, but brick structures were common by 1700. During the 18th century, the cityscape was dominated by Georgian architecture, including Independence Hall and Christ Church.

In the first decades of the 19th century, Federal and Greek Revival architecture were the dominant styles produced by Philadelphia architects such as Benjamin Latrobe, William Strickland, John Haviland, John Notman, Thomas Walter, and Samuel Sloan. Frank Furness is considered Philadelphia's greatest architect of the second half of the 19th century. His contemporaries included John McArthur Jr., Addison Hutton, Wilson Eyre, the Wilson Brothers, and Horace Trumbauer. In 1871, construction began on the Second Empire-style Philadelphia City Hall. The Philadelphia Historical Commission was created in 1955 to preserve the cultural and architectural history of the city. The commission maintains the Philadelphia Register of Historic Places, adding historic buildings, structures, sites, objects and districts as it sees fit.

In 1932, Philadelphia became home to the first modern International Style skyscraper in the United States, the PSFS Building, designed by George Howe and William Lescaze. The 548 ft (167 m) City Hall remained the tallest building in the city until 1987 when One Liberty Place was completed. Numerous glass and granite skyscrapers were built in Center City beginning in the late 1980s. In 2007, the Comcast Center surpassed One Liberty Place to become the city's tallest building. The Comcast Technology Center was completed in 2018, reaching a height of 1,121 ft (342 m), as the tallest building in the United States outside of Manhattan and Chicago.

For much of Philadelphia's history, the typical home has been the row house. The row house was introduced to the United States via Philadelphia in the early 19th century and, for a time, row houses built elsewhere in the United States were known as "Philadelphia rows". A variety of row houses are found throughout the city, from Federal-style continuous blocks in Old City and Society Hill to Victorian-style homes in North Philadelphia to twin row houses in West Philadelphia. While newer homes have been built recently, much of the housing dates to the 18th, 19th, and early 20th centuries, which has created problems such as urban decay and vacant lots. Some neighborhoods, including Northern Liberties and Society Hill, have been rehabilitated through gentrification.

Parks As of 2014, the city's total park space, including municipal, state, and federal parks in the city, amounts to 11,211 acres (17.5 sq mi). Philadelphia's largest park is Fairmount Park, which includes the Philadelphia Zoo and encompasses 2,052 acres (3.2 sq mi) of the total parkland. Fairmount Park's adjacent Wissahickon Valley Park contains 2,042 acres (3.2 sq mi). Fairmount Park, when combined with Wissahickon Valley Park, is one of the largest contiguous urban park areas in the U.S. The two parks, along with the Colonial Revival, Georgian and Federal-style mansions in them, have been listed as one entity on the National Register of Historic Places since 1972.

Corporations The city is home to the Philadelphia Stock Exchange and the headquarters of cable television and internet provider Comcast, Brandywine Realty Trust, insurance companies Cigna, Colonial Penn, and Independence Blue Cross, food services company Aramark, chemical makers FMC Corporation and Rohm and Haas, pharmaceutical company GlaxoSmithKline, apparel retailer Urban Outfitters and its subsidiaries including Anthropologie, automotive parts retailer Pep Boys, and stainless steel producer Carpenter Technology Corporation. The headquarters of Boeing Rotorcraft Systems, and its main rotorcraft factory, are in the Philadelphia suburb of Ridley Park, while The Vanguard Group and the US headquarters of Siemens Healthineers are headquartered in suburban Malvern.

Tech and biotech Philadelphia has emerged as a hub for information technology and biotechnology. Philadelphia and Pennsylvania are attracting new life sciences ventures. The Philadelphia metropolitan area, comprising the Delaware Valley, has also become a growing hub for venture capital funding.

Tourist Industry Philadelphia's history attracts many tourists, with the Independence National Historical Park (which includes the Liberty Bell, Independence Hall, and other historic sites) receiving over 5 million visitors in 2016. The city welcomed 42 million domestic tourists in 2016 who spent $6.8 billion, generating an estimated $11 billion in total economic impact in the city and surrounding four counties of Pennsylvania.

Trade and transportation Philadelphia International Airport and the Port of Philadelphia are key to the city's international connections. Philadelphia's 30th Street Station is the third-busiest Amtrak rail hub, carrying over 4 million inter-city rail passengers annually.

Education: Primary and Secondary Education in Philadelphia is provided by many private and public institutions. The School District of Philadelphia is the local school district, operating public schools, in all of the city. The Philadelphia School District is the eighth-largest school district in the nation with 142,266 students in 218 traditional public schools and 86 charter schools as of 2014.

The city's K-12 enrollment in district–run schools dropped from 156,211 students in 2010 to 130,104 students in 2015. During the same time period, the enrollment in charter schools increased from 33,995 students in 2010 to 62,358 students in 2015. This consistent drop in enrollment led the city to close 24 of its public schools in 2013. During the 2014 school year, the city spent an average of $12,570 per pupil, below the average among comparable urban school districts.

Graduation rates among district-run schools, meanwhile, steadily increased in the ten years from 2005. In 2005, Philadelphia had a district graduation rate of 52%. This number increased to 65% in 2014, still below the national and state averages. Scores on the state's standardized test, the Pennsylvania System of School Assessment (PSSA) trended upward from 2005 to 2011 but subsequently decreased. In 2005, the district-run schools scored an average of 37.4% on math and 35.5% on reading. The city's schools reached their peak scores in 2011 with 59.0% on math and 52.3% on reading. In 2014, the scores dropped significantly to 45.2% on math and 42.0% on reading.

Of the city's public high schools, including charter schools, only four performed above the national average on the SAT (1497 out of 2400) in 2014: Masterman, Central, Girard Academic Music Program, and MaST Community Charter School. All other district-run schools were below average.

The city's major art museum, the Philadelphia Museum of Art, is one of the largest art museums in the world. The long flight of steps to the Art Museum's main entrance became famous after the film Rocky (1976).

Areas such as South Street and Old City have a vibrant night life. The Avenue of the Arts in Center City contains many restaurants and theaters, such as the Kimmel Center for the Performing Arts, home of the Philadelphia Orchestra, and the Academy of Music, home of Opera Philadelphia and the Pennsylvania Ballet.

In May 2019, the Walnut Street Theatre announced a major expansion to begin in 2020. New Freedom Theatre, which is Pennsylvania's oldest African-American theatre, sits on North Broad Street.

Philadelphia has more public art than any other American city. In 1872, the Association for Public Art (formerly the Fairmount Park Art Association) was created as the first private association in the United States dedicated to integrating public art and urban planning. In 1959, lobbying by the Artists Equity Association helped create the Percent for Art ordinance, the first for a U.S. city. The program, which has funded more than 200 pieces of public art, is administered by the Philadelphia Office of Arts and Culture, the city's art agency. The city also has more murals than any other American city, due to the 1984 creation of the Department of Recreation's Mural Arts Program, which seeks to beautify neighborhoods and provide an outlet for graffiti artists. The program has funded more than 2,800 murals by professional, staff and volunteer artists and educated more than 20,000 youth in underserved neighborhoods throughout Philadelphia.

The city is home to a number of art organizations including the regional art advocacy nonprofit Philadelphia Tri-State Artists Equity, the Philadelphia Sketch Club, one of the country's oldest artists' clubs, and The Plastic Club, started by women excluded from the Sketch Club.

The orchestra performs at the Kimmel Center and has a summer concert series at the Mann Center for the Performing Arts. Opera Philadelphia performs at the nation's oldest continually operating opera house—the Academy of Music. The Philadelphia Boys Choir & Chorale has performed its music all over the world. The Philly Pops plays orchestral versions of popular jazz, swing, Broadway, and blues songs at the Kimmel Center and other venues within the mid-Atlantic region. The Curtis Institute of Music is one of the world's premier conservatories and among the most selective institutes of higher education in the nation.

Philadelphia has played a prominent role in the music of the United States. The culture of American popular music has been influenced by significant contributions of Philadelphia area musicians and producers, in both the recording and broadcasting industries. In 1952, the teen dance party program called Bandstand premiered on local television, hosted by Bob Horn. The show was renamed American Bandstand in 1957, when it began national syndication on ABC, hosted by Dick Clark and produced in Philadelphia until 1964 when it moved to Los Angeles. Promoters marketed youthful musical artists known as teen idols to appeal to the young audience. Philadelphia-born singers such as Frankie Avalon, James Darren, Eddie Fisher, Fabian Forte, and Bobby Rydell, along with South Philly-raised Chubby Checker, topped the music charts, establishing a clean-cut rock and roll image.

Philly soul music of the late 1960s–1970s is a highly produced version of soul music which led to later forms of popular music such as disco and urban contemporary rhythm and blues. On July 13, 1985, John F. Kennedy Stadium was the American venue for the Live Aid concert. The city also hosted the Live 8 concert, which attracted about 700,000 people to the Benjamin Franklin Parkway on July 2, 2005.

Notable rock and pop musicians from Philadelphia and its suburbs include Bill Haley & His Comets, Nazz, Todd Rundgren, Hall & Oates, the Hooters, Cinderella, DJ Jazzy Jeff & the Fresh Prince, Ween, Schoolly D, Pink, the Roots, Beanie Sigel, State Property, Lisa "Left Eye" Lopes, Meek Mill, Lil Uzi Vert, and others.

Cuisine The city is known for its hoagies, stromboli, roast pork sandwich, scrapple, soft pretzels, water ice, Irish potato candy, tastykakes, and the cheesesteak sandwich which was developed by Italian immigrants. The Philadelphia area has many establishments that serve cheesesteaks, including restaurants, taverns, delicatessens and pizza parlors. The originator of the thinly-sliced steak sandwich in the 1930s, initially without cheese, is Pat's King of Steaks, which faces its rival Geno's Steaks, founded in 1966, across the intersection of 9th Street and Passyunk Avenue in the Italian Market of South Philadelphia.

McGillin's Olde Ale House, opened in 1860 on Drury Street in Center City, is the oldest continuously operated tavern in the city. The City Tavern is a replica of a historic 18th-century building first opened in 1773, demolished in 1854 after a fire, and rebuilt in 1975 on the same site as part of Independence National Historical Park. The tavern offers authentic 18th-century recipes, served in seven period dining rooms, three wine cellar rooms and an outdoor garden.

The Reading Terminal Market is a historic food market founded in 1893 in the Reading Terminal building, a designated National Historic Landmark. The enclosed market is one of the oldest and largest markets in the country, hosting over a hundred merchants offering Pennsylvania Dutch specialties, artisan cheese and meat, locally grown groceries, and specialty and ethnic foods.

Dialect The traditional Philadelphia accent is considered by some linguists to be the most distinctive accent in North America. The Philadelphia dialect, which is spread throughout the Delaware Valley and South Jersey, is part of a larger Mid-Atlantic American English family, a designation that also includes the Baltimore dialect. Additionally, it shares many similarities with the New York accent. Owing to over a century of linguistic data collected by researchers at the University of Pennsylvania under sociolinguist William Labov, the Philadelphia dialect has been one of the best-studied forms of American English. The accent is especially found within the Irish American and Italian American working-class neighborhoods. Philadelphia also has its own unique collection of neologisms and slang terms.

Sport Philadelphia's first professional sports team was baseball's Athletics, organized in 1860. The Athletics were initially an amateur league team that turned professional in 1871, and then became a founding team of the current National League in 1876. The city is one of 13 U.S. cities to have teams in all four major league sports: the Philadelphia Phillies of Major League Baseball (MLB), the Philadelphia Eagles of the National Football League (NFL), the Philadelphia Flyers of the National Hockey League (NHL), and the Philadelphia 76ers of the National Basketball Association (NBA). The Phillies, formed in 1883 as the Quakers and renamed in 1884, are the oldest team continuously playing under the same name in the same city in the history of American professional sports.

The Philadelphia metro area is also home to the Philadelphia Union of Major League Soccer (MLS). The Union began playing their home games in 2010 at PPL Park, a soccer-specific stadium in Chester, Pennsylvania. The stadium's name was changed to Talen Energy Stadium in 2016 and to Subaru Park in 2020.

Philadelphia was the second of eight American cities to have won titles in all four major leagues (MLB, NFL, NHL and NBA), and also has a title in soccer from the now-defunct North American Soccer League in the 1970s. The city's professional teams and their fans endured 25 years without a championship, from the 76ers 1983 NBA Finals win until the Phillies 2008 World Series win. The lack of championships was sometimes attributed in jest to the Curse of Billy Penn after One Liberty Place became the first building to surpass the height of the William Penn statue on top of City Hall's tower in 1987. After nine years passed without another championship, the Eagles won their first Super Bowl following the 2017 season. In 2004, ESPN placed Philadelphia second on its list of The Fifteen Most Tortured Sports Cities. Fans of the Eagles and Phillies were singled out as the worst fans in the country by GQ magazine in 2011, which used the subtitle of "Meanest Fans in America" to summarize incidents of drunken behavior and a history of booing.

Major professional sports teams that originated in Philadelphia but later moved to other cities include the Golden State Warriors basketball team, which played in Philadelphia from 1946 to 1962 and the Oakland Athletics baseball team, which was originally the Philadelphia Athletics and played in Philadelphia from 1901 to 1954.

Philadelphia is home to professional, semi-professional, and elite amateur teams in cricket, rugby league (Philadelphia Fight), and rugby union. Major running events in the city include the Penn Relays (track and field), the Philadelphia Marathon, and the Broad Street Run. The Collegiate Rugby Championship is played every June at Talen Energy Stadium in Chester.

Rowing has been popular in Philadelphia since the 18th century. Boathouse Row is a symbol of Philadelphia's rich rowing history, and each Big Five member has its own boathouse. Philadelphia hosts numerous local and collegiate rowing clubs and competitions, including the annual Dad Vail Regatta, which is the largest intercollegiate rowing event in North America with more than 100 U.S. and Canadian colleges and universities participating; the annual Stotesbury Cup Regatta, which is billed as the world's oldest and largest rowing event for high school students; and the Head of the Schuylkill Regatta. The regattas are held on the Schuylkill River and organized by the Schuylkill Navy, an association of area rowing clubs that has produced numerous Olympic rowers.

The Philadelphia Spinners were a professional ultimate team in Major League Ultimate (MLU) until 2016. The Spinners were one of the original eight teams of the American Ultimate Disc League (AUDL) that began in 2012. They played at Franklin Field and won the inaugural AUDL championship and the final MLU championship in 2016. The MLU was suspended indefinitely by its investors in December 2016. As of 2018, the Philadelphia Phoenix continue to play in the AUDL.

Philadelphia is home to the Philadelphia Big 5, a group of five NCAA Division I college basketball programs. The Big 5 include La Salle, Penn, Saint Joseph's, Temple, and Villanova universities.

Philadelphia will be one of the eleven US host cities for the 2026 FIFA World Cup.

Law and government Philadelphia County is a legal nullity. All county functions were assumed by the city in 1952. The city has been coterminous with the county since 1854.

Philadelphia's 1952 Home Rule Charter was written by the City Charter Commission, which was created by the Pennsylvania General Assembly in an act of April 21, 1949, and a city ordinance of June 15, 1949. The existing city council received a proposed draft on February 14, 1951, and the electors approved it in an election held April 17, 1951. The first elections under the new Home Rule Charter were held in November 1951, and the newly elected officials took office in January 1952.

The city uses the strong-mayor version of the mayor–council form of government, which is led by one mayor in whom executive authority is vested. The mayor has the authority to appoint and dismiss members of all boards and commissions without the approval of the city council. Elected at-large, the mayor is limited to two consecutive four-year terms, but can run for the position again after an intervening term.

Courts Philadelphia County is coterminous with the First Judicial District of Pennsylvania. The Philadelphia County Court of Common Pleas is the trial court of general jurisdiction for the city, hearing felony-level criminal cases and civil suits above the minimum jurisdictional limit of $10,000. The court also has appellate jurisdiction over rulings from the Municipal and Traffic Courts, and some administrative agencies and boards. The trial division has 70 commissioned judges elected by the voters, along with about one thousand other employees. The court also has a family division with 25 judges and an orphans' court with three judges.

The Philadelphia Municipal Court handles traffic cases, misdemeanor and felony criminal cases with maximum incarceration of five years, and civil cases involving $12,000 or less ($15,000 in real estate and school tax cases), and all landlord-tenant disputes. The municipal court has 27 judges elected by the voters.

Pennsylvania's three appellate courts also have sittings in Philadelphia. The Supreme Court of Pennsylvania, the court of last resort in the state, regularly hears arguments in Philadelphia City Hall. The Superior Court of Pennsylvania and the Commonwealth Court of Pennsylvania also sit in Philadelphia several times a year. Judges for these courts are elected at large. The state Supreme Court and Superior Court have deputy prothonotary offices in Philadelphia.

Additionally, Philadelphia is home to the federal United States District Court for the Eastern District of Pennsylvania and the Court of Appeals for the Third Circuit, both of which are housed in the James A. Byrne United States Courthouse.

Environmental policy "Green Cities, Clean Water" is an environmental policy initiative based in Philadelphia that has shown promising results in mitigating the effects of climate change. The researchers on the policy have stated that despite such promising plans of green infrastructure building, "the city is forecasted to grow warmer, wetter, and more urbanized over the century, runoff and local temperatures will increase on average throughout the city". Even though landcover predictive models on the effects of the policy initiative have indicated that green infrastructure could be useful at decreasing the amount of runoff in the city over time, the city government would have to expand its current plans and "consider the cobenefit of climate change adaptation when planning new projects'' in limiting the scope of city-wide temperature increase.

Public safety According to a 2015 report by Pew Charitable Trusts, the police districts with the highest rates of violent crime were Frankford (15th district) and Kensington (24th district) in the Near Northeast, and districts to the North (22nd, 25th, and 35th districts), West (19th district) and Southwest (12th district) of Center City. Each of those seven districts recorded more than a thousand violent crimes in 2014. The lowest rates of violent crime occurred in Center City, South Philadelphia, the Far Northeast, and Roxborough districts, the latter of which includes Manayunk.

Philadelphia had 500 (503 according to some sources) murders in 1990, a rate of 31.5 per 100,000. An average of about 400 murders occurred each year for most of the 1990s. The murder count dropped in 2002 to 288, then rose to 406 by 2006, before dropping slightly to 392 in 2007. A few years later, Philadelphia began to see a rapid decline in homicides and violent crime. In 2013, the city had 246 murders, which is a decrease of nearly 40% since 2006. In 2014, 248 homicides were committed. The homicide rate rose to 280 in 2015, then fell slightly to 277 in 2016, before rising again to 317 in 2017. Homicides increased dramatically in the late 2010s/early 2020s, reaching 499 homicides in 2020 and surpassing the 1990 "record" in 2021, with 501st murder on November 27 and 510 by the end of the month.

In 2006, Philadelphia's homicide rate of 27.7 per 100,000 people was the highest of the country's 10 most populous cities. In 2012, Philadelphia had the fourth-highest homicide rate among the country's most populous cities. The rate dropped to 16 homicides per 100,000 residents by 2014 placing Philadelphia as the sixth-highest city in the country.

The number of shootings in the city has declined significantly since the early years of the 21st century. Shooting incidents peaked at 1,857 in 2006 before declining nearly 44 percent to 1,047 shootings in 2014. Major crimes have decreased gradually since a peak in 2006 when 85,498 major crimes were reported. The number of reported major crimes fell 11 percent in three years to 68,815 occurrences in 2014. Violent crimes, which include homicide, rape, aggravated assault, and robbery, decreased 14 percent in three years to 15,771 occurrences in 2014.

In 2014, Philadelphia enacted an ordinance decriminalizing the possession of less than 30 grams of marijuana or 8 grams of hashish; the ordinance gave police officers the discretion to treat possession of these amounts as a civil infraction punishable by a $25 ticket, rather than a crime. Philadelphia was at the time the largest city to decriminalize the possession of marijuana. From 2013 to 2018, marijuana arrests in the city dropped by more than 85%. The purchase or sale of marijuana remains a criminal offense in Philadelphia.

Firefighting The Philadelphia Fire Department provides fire protection and emergency medical services (EMS). The department's official mission is to protect public safety by quick and professional response to emergencies and the promotion of sound emergency prevention measures. This mandate encompasses all traditional firefighting functions, including fire suppression, with 60 engine companies and 30 ladder companies as well as specialty and support units deployed throughout the city; specialized firefighting units for Philadelphia International Airport and the Port of Philadelphia; investigations conducted by the fire marshal's office to determine the origins of fires and develop preventive strategies; prevention programs to educate the public; and support services including research and planning, management of the fire communications centre within the city's 911 system, and operation of the Philadelphia Fire Academy.

Transport Philadelphia is served by SEPTA, which operates buses, trains, rapid transit (as both subways and elevated trains), trolleys, and trackless trolleys (electric buses) throughout Philadelphia, the four Pennsylvania suburban counties of Bucks, Chester, Delaware, and Montgomery, in addition to service to Mercer County, New Jersey (Trenton) and New Castle County, Delaware (Wilmington and Newark, Delaware). The city's subway system consists of two routes: the subway section of the Market–Frankford Line running east–west under Market Street which opened in 1905 to the west and 1908 to the east of City Hall, and the Broad Street Line running north–south beneath Broad Street which opened in stages from 1928 to 1938.

Beginning in the 1980s, large sections of the SEPTA Regional Rail service to the far suburbs of Philadelphia were discontinued due to a lack of funding for equipment and infrastructure maintenance.

Philadelphia's 30th Street Station is a major railroad station on Amtrak's Northeast Corridor with 4.4 million passengers in 2017 making it the third-busiest station in the country after New York City's Pennsylvania Station and Washington's Union Station. 30th Street Station offers access to Amtrak, SEPTA, and NJ Transit lines. Over 12 million SEPTA and NJ Transit rail commuters use the station each year, and more than 100,000 people on an average weekday.

The PATCO Speedline provides rapid transit service to Camden, Collingswood, Westmont, Haddonfield, Woodcrest (Cherry Hill), Ashland (Voorhees), and Lindenwold, New Jersey, from stations on Locust Street between 16th and 15th, 13th and 12th, and 10th and 9th Streets, and on Market Street at 8th Street.

Philadelphia International Airport is among the busiest airports in the world measured by traffic movements (i.e., takeoffs and landings). More than 30 million passengers pass through the airport annually on 25 airlines, including all major domestic carriers. The airport has nearly 500 daily departures to more than 120 destinations worldwide. SEPTA's Airport Regional Rail Line provides direct service between Center City railroad stations and Philadelphia International Airport.

Transport: Road William Penn planned Philadelphia with numbered streets traversing north and south, and streets named for trees, such as Chestnut, Walnut, and Mulberry (since renamed Arch Street), traversing east and west. The two main streets were named Broad Street (the north–south artery, since designated Pennsylvania Route 611) and High Street (the east–west artery, since renamed Market Street) converging at Centre Square which later became the site of City Hall.

Interstate 95 (the Delaware Expressway) traverses the southern and eastern edges of the city along the Delaware River as the main north–south controlled-access highway, connecting Philadelphia with Newark, New Jersey and New York City to the north and with Baltimore and Washington, D.C. southward. The city is also served by Interstate 76 (the Schuylkill Expressway), which runs along the Schuylkill River, intersecting the Pennsylvania Turnpike at King of Prussia and providing access to Harrisburg and points west. Interstate 676 (the Vine Street Expressway) links I-95 and I-76 through Center City by running below street level between the eastbound and westbound lanes of Vine Street. Entrance and exit ramps for the Benjamin Franklin Bridge are near the eastern end of the expressway, just west of the I-95 interchange.

The Roosevelt Boulevard and Expressway (U.S. 1) connect Northeast Philadelphia with Center City via I-76 through Fairmount Park. Woodhaven Road (Route 63) and Cottman Avenue (Route 73) serve the neighborhoods of Northeast Philadelphia, running between I-95 and the Roosevelt Boulevard. The Fort Washington Expressway (Route 309) extends north from the city's northern border, serving Montgomery County and Bucks County. U.S. Route 30 (Lancaster Avenue) extends westward from West Philadelphia to Lancaster.

Interstate 476 (locally referred to as the Blue Route) traverses Delaware County, bypassing the city to the west and serving the city's western suburbs, and provides a direct route to Allentown and points north, including the Poconos. Interstate 276, the Pennsylvania Turnpike's Delaware River extension, is a bypass and commuter route to the north of the city and a link to the New Jersey Turnpike and New York City.

The Delaware River Port Authority operates four bridges in the Philadelphia area across the Delaware River to New Jersey: the Walt Whitman Bridge (I-76), the Benjamin Franklin Bridge (I-676 and U.S. 30), the Betsy Ross Bridge (New Jersey Route 90), and the Commodore Barry Bridge (U.S. 322 in Delaware County, south of the city). The Burlington County Bridge Commission maintains two bridges across the Delaware River: the Tacony–Palmyra Bridge which connects PA Route 73 in the Tacony section of Northeast Philadelphia with New Jersey Route 73 in Palmyra, Burlington County, and the Burlington–Bristol Bridge which connects NJ Route 413/U.S. Route 130 in Burlington, New Jersey with PA Route 413/U.S. 13 in Bristol Township, north of Philadelphia.

Transport: Rail Since the early days of rail transportation in the United States, Philadelphia has served as a hub for several major rail companies, particularly the Pennsylvania Railroad and the Reading Railroad. The Pennsylvania Railroad first operated Broad Street Station, then 30th Street Station and Suburban Station, and the Reading Railroad operated Reading Terminal, now part of the Pennsylvania Convention Center. The two companies also operated competing commuter rail systems in the area. The two systems now operate as a single system under the control of SEPTA, the regional transit authority. Additionally, the PATCO Speedline subway system and NJ Transit's Atlantic City Line operate successor services to southern New Jersey.

In 1911, Philadelphia had nearly 4,000 electric trolleys running on 86 lines. In 2005, SEPTA reintroduced trolley service to the Girard Avenue Line, Route 15. SEPTA operates six subway-surface trolleys that run on street-level tracks in West Philadelphia and subway tunnels in Center City, along with two surface trolleys in adjacent suburbs.

Philadelphia is a regional hub of the federally-owned Amtrak system, with 30th Street Station being a primary stop on the Washington-Boston Northeast Corridor and the Keystone Corridor to Harrisburg and Pittsburgh. 30th Street also serves as a major station for services via the Pennsylvania Railroad's former Pennsylvania Main Line to Chicago. As of 2018, 30th Street is Amtrak's third-busiest station in the country, after New York City and Washington.

Walk Score A 2017 study by Walk Score ranked Philadelphia the fifth-most walkable major city in the United States with a score of 79 out of 100, in the middle of the "very walkable" range. The city was just edged out by fourth place Miami (79.2), with the top three cities being New York, San Francisco, and Boston. Philadelphia placed fifth in the public transit friendly category, behind Washington, D.C., with the same three cities for walkability topping this category. The city ranked tenth in the bike friendly cities category, with the top three cities being Minneapolis, San Francisco and Portland.

USA Today readers voted the Schuylkill River Trail the best urban trail in the nation in 2015.

Utilities: Water In 1815, Philadelphia began sourcing its water via the Fairmount Water Works on the Schuylkill River, the nation's first major urban water supply system. In 1909, the Water Works was decommissioned as the city transitioned to modern sand filtration methods. Today, the Philadelphia Water Department (PWD) provides drinking water, wastewater collection, and stormwater services for Philadelphia, as well as surrounding counties. PWD draws about 57 percent of its drinking water from the Delaware River and the balance from the Schuylkill River. The city has two filtration plants on the Schuylkill River and one on the Delaware River. The three plants can treat up to 546 million gallons of water per day, while the total storage capacity of the combined plant and distribution system exceeds one billion gallons. The wastewater system consists of three water pollution control plants, 21 pumping stations, and about 3,657 miles (5,885 km) of sewers.

Electricity Exelon subsidiary PECO Energy Company, founded as the Brush Electric Light Company of Philadelphia in 1881 and renamed Philadelphia Electric Company (PECO) in 1902, provides electricity to about 1.6 million customers and more than 500,000 natural gas customers in the south-eastern Pennsylvania area including the city of Philadelphia and most of its suburbs. PECO is the largest electric and natural gas utility in the state with 472 power substations and nearly 23,000 miles (37,000 km) of electric transmission and distribution lines, along with 12,000 miles (19,000 km) of natural gas transmission, distribution & service lines.

Natural gas Philadelphia Gas Works (PGW), overseen by the Pennsylvania Public Utility Commission, is the nation's largest municipally-owned natural gas utility. PGW serves over 500,000 homes and businesses in the Philadelphia area. Founded in 1836, the company came under city ownership in 1987 and has been providing the majority of gas distributed within city limits. In 2014, the City Council refused to conduct hearings on a $1.86 billion sale of PGW, part of a two-year effort that was proposed by the mayor. The refusal led to the prospective buyer terminating its offer.

Telecommunications Southeastern Pennsylvania was assigned the 215 area code in 1947 when the North American Numbering Plan of the Bell System went into effect. The geographic area covered by the code was split nearly in half in 1994 when area code 610 was created, with the city and its northern suburbs retaining 215. Overlay area code 267 was added to the 215 service area in 1997, and 484 was added to the 610 area in 1999. A plan in 2001 to introduce a third overlay code to both service areas, area code 445 to 215 and area code 835 to 610, was delayed and later rescinded. Area code 445 was implemented as an overlay for area codes 215 and 267 starting on February 3, 2018.
