According to the United States Census Bureau, the city has a total area of 17.0 square miles (44Â km), of which 10.9 square miles (28Â km2) is land and 6.2 square miles (16Â km) is water. The total area is 36.25% water.
The city sits at the confluence of the Christina and Delaware rivers, approximately 33 miles (53Â km) southwest of Philadelphia. Wilmington Train Station, one of the southernmost stops on Philadelphia's SEPTA rail transportation system, is also served by Northeast Corridor Amtrak passenger trains. Wilmington is served by I-95 and I-495 within city limits. In addition, the twin-span Delaware Memorial Bridge, a few miles south of the city, provides direct highway access between Delaware and New Jersey, carrying the I-295 eastern bypass route around Wilmington and Philadelphia, as well as US 40, which continues eastward to Atlantic City, New Jersey.
These transportation links and geographic proximity give Wilmington some of the characteristics of a satellite city to Philadelphia, but Wilmington's long history as Delaware's principal city, its urban core, and its independent value as a business destination makes it more properly considered a small but independent city in the Philadelphia metropolitan area.
Wilmington lies along the Fall Line geological transition from the Mid-Atlantic Piedmont Plateau to the Atlantic Coastal Plain. East of Market Street, and along both sides of the Christina River, the Coastal Plain land is flat, low-lying, and in places marshy. The Delaware River here is an estuary at sea level (with twice-daily high and low tides), providing sea-level access for ocean-going ships.
On the western side of Market Street, the Piedmont topography is rocky and hilly, rising to a point that marks the watershed between the Brandywine River and the Christina River. This watershed line runs along Delaware Avenue westward from 10th Street and Market Street.
These contrasting topography and soil conditions affected the industrial and residential development patterns within the city. The hilly west side was more attractive for the original residential areas, offering springs and sites for mills, better air quality, and fewer mosquitoes.
Wilmington has a warm temperate climate or humid subtropical climate (Köppen Cfa), with hot and humid summers, cool to cold winters, and precipitation evenly spread throughout the year. In July, the daily average is 76.8 °F (24.9 °C), with an average 21 days of 90 °F (32 °C)+ highs annually. Summer thunderstorms are common in the hottest months. The January daily average is 32.4 °F (0.2 °C), although temperatures may occasionally reach 10 °F (−12 °C) or 55 °F (13 °C) as fronts move toward and past the area. Snowfall is light to moderate, and variable, with some winters bringing very little of it and others witnessing several major snowstorms; the average seasonal total is 20.2 inches (51 cm). Extremes in temperature have ranged from −15 °F (−26 °C) on February 9, 1934, up to 107 °F (42 °C) on August 7, 1918, though both 100 °F (38 °C)+ and 0 °F (−18 °C) readings are uncommon; the last occurrence of each was July 18, 2012 and February 5, 1996, respectively.

Wilmington is built on the site of Fort Christina and the settlement Kristinehamn, the first Swedish settlement in North America. The modern city also encompasses other Swedish settlements, such as Timmerön / Timber Island (along Brandywine Creek), Sidoland (South Wellington), Strandviken (along the Delaware River near Simonds Garden) and Översidolandet (along the Christina River, near Woodcrest and Ashley Heights).
The area now known as Wilmington was settled by the Lenape (or Delaware Indian) band led by Sachem (Chief) Mattahorn just before Henry Hudson sailed up the Len-api Hanna ("People Like Me River", present Delaware River) in 1609. The area was called "Maax-waas Unk" or "Bear Place" after the Maax-waas Hanna (Bear River) that flowed by (present Christina River). It was called the Bear River because it flowed west to the "Bear People", who are now known as the People of Conestoga or the Susquehannocks.
The Dutch heard and spelled the river and the place as Minguannan. When settlers and traders from the Swedish South Company under Peter Minuit arrived in March 1638 on the Fogel Grip and Kalmar Nyckel, they purchased Maax-waas Unk from Chief Mattahorn and built Fort Christina at the mouth of the Maax-waas Hanna (which the Swedes renamed the Christina River after Queen Christina of Sweden). The area was also known as "The Rocks", and is located near the foot of present-day Seventh Street. Fort Christina served as the headquarters for the colony of New Sweden which consisted of, for the most part, the lower Delaware River region (parts of present-day Delaware, Pennsylvania, and New Jersey), but few colonists settled there. Dr. Timothy Stidham (Swedish:Timen Lulofsson Stiddem) was a prominent citizen and doctor in Wilmington. He was born in 1610, probably in Hammel, Denmark, and raised in Gothenburg, Sweden. He arrived in New Sweden in 1654 and is recorded as the first physician in Delaware.
The most important Swedish governor was Colonel Johan Printz, who ruled the colony under Swedish law from 1643 to 1653. He was succeeded by Johan Rising, who upon his arrival in 1654, seized the Dutch post Fort Casimir, located at the site of the present town of New Castle, which was built by the Dutch in 1651. Rising governed New Sweden until the autumn of 1655, when a Dutch fleet under the command of Peter Stuyvesant subjugated the Swedish forts and established the authority of the Colony of New Netherland throughout the area formerly controlled by the Swedes. This marked the end of Swedish rule in North America.
Beginning in 1664 British colonization began; after a series of wars between the Dutch and English, the area stabilized under British rule, with strong influences from the Quaker communities under the auspices of Proprietor William Penn. A borough charter was granted in 1739 by King George II, which changed the name of the settlement from Willington, after Thomas Willing (the first developer of the land, who organized the area in a grid pattern similar to that of its northern neighbor Philadelphia), to Wilmington, presumably after the British Prime Minister Spencer Compton, Earl of Wilmington, who took his title from Wilmington, East Sussex, in southern England.
Although during the American Revolutionary War only one small battle was fought in Delaware, British troops occupied Wilmington shortly after the nearby Battle of Brandywine on September 11, 1777. The British remained in the town until they vacated Philadelphia in 1778.
In 1800, Eleuthère Irénée du Pont, a French Huguenot, emigrated to the United States. Knowledgeable in the manufacture of gunpowder, by 1802 DuPont had begun making the explosive in a mill on the Brandywine River north of Brandywine Village and just outside the town of Wilmington. The DuPont company became a major supplier to the U.S. military. Located on the banks of the Brandywine River, the village was eventually annexed by Wilmington city.
The greatest growth in the city occurred during the Civil War. Delaware, though officially remaining a member of the Union, was a border state and divided in its support of both the Confederate and the Union causes. The war created enormous demand for goods and materials supplied by Wilmington including ships, railroad cars, gunpowder, shoes, and other war-related goods.
By 1868, Wilmington was producing more iron ships than the rest of the country combined and it rated[by whom?] first in the production of gunpowder and second in carriages and leather. Due to the prosperity Wilmington enjoyed during the war, city merchants and manufacturers expanded Wilmington's residential boundaries westward in the form of large homes along tree-lined streets. This movement was spurred by the first horsecar line, which was initiated in 1864 along Delaware Avenue.
The late 19th century saw the development of the city's first comprehensive park system. William Poole Bancroft, a successful Wilmington businessman influenced by the work of Frederick Law Olmsted, led the effort to establish open parkland in Wilmington. Rockford Park and Brandywine Park were created due to Bancroft's efforts.
Both World Wars stimulated the city's industries. Industries vital to the war effort – shipyards, steel foundries, machinery, and chemical producers – operated around the clock. Other industries produced such goods as automobiles, leather products, and clothing. In desperate need of workers more and more minorities moved to the north and settled in places like Wilmington. This led to tensions that occasionally boiled over like the Wilmington, Delaware race riot of 1919.
The post-war prosperity again pushed residential development further out of the city. In the 1950s, more people began living in the suburbs of North Wilmington and commuting into the city to work. This was made possible by extensive upgrades to area roads and highways and through the construction of Interstate 95, which cut through several of Wilmington's neighborhoods and accelerated the city's population decline. Urban renewal projects in the 1950s and 1960s cleared entire blocks of housing in the Center City and East Side areas.
The Wilmington riot of 1968, a few days after the April 4 assassination of Martin Luther King Jr., became national news. On April 9, Governor Charles L. Terry, Jr. deployed the National Guard and the Delaware State Police to the city at the request of Mayor John Babiarz. Babiarz asked Terry to withdraw the National Guard the following week, but the governor kept them in the city until his term ended in January 1969. This is reportedly the longest occupation of an American city by state forces in the nation's history.
In the 1980s, job growth and office construction were spurred by the arrival of national banks and financial institutions in the wake of the 1981 Financial Center Development Act, which liberalized the laws governing banks operating within the state, and similar laws in 1986. Today, many national and international banks, including Bank of America, Capital One, Chase, and Barclays, have operations in the city, typically credit card operations.
The Wilmington City Council consists of thirteen members. The council consists of eight members who are elected from geographic districts, four elected at-large and the City Council President. The Council President is elected by the entire city. The Mayor of Wilmington is also elected by the entire city.
The current mayor of Wilmington is Mike Purzycki (D). The current city council members are listed in the table below.
The Delaware Department of Correction Howard R. Young Correctional Institution, renamed from Multi-Purpose Criminal Justice Facility in 2004 and housing both pretrial and posttrial male prisoners, is located in Wilmington. The prison is often referred to as the "Gander Hill Prison" after the neighborhood it is located in. The prison opened in 1982.
Many Wilmington City workers belong to one of several Locals of the American Federation of State, County and Municipal Employees union.
Interstate 95, which splits Wilmington roughly into eastern and western halves, provides access to major markets in the Northeast and nationwide. Interstate 495 is a bypass passing through the east side of the city, and Interstate 295 is south of the city, crossing the Delaware River into New Jersey on the Delaware Memorial Bridge. U.S. Route 13 passes north–south through the eastern part of Wilmington, entering the city from the south along Dupont Highway before following Heald Street, the one-way pair of Church Street northbound and Spruce Street southbound, and Governor Printz Boulevard. U.S. Route 13 Business passes north–south through the center of Wilmington, entering the city from the south on Market Street before splitting into Walnut Street northbound and Market Street southbound, following Walnut Street northbound and King Street southbound in the downtown area, and following Market Street northeast out of the city to Philadelphia Pike. U.S. Route 202 follows I-95 through Wilmington before heading north onto Concord Pike through a business area to the north of the city. State routes serving Wilmington include Delaware Route 2, which follows the one-way pair of Lincoln Street eastbound and Union Street westbound in the western part of the city before heading west out of the city along Kirkwood Highway; Delaware Route 4, which heads southwest from the downtown area along Maryland Avenue; Delaware Route 9, which enters the city from the south along New Castle Avenue before crossing the Christina River and heading west through the center of the city along 4th Street; Delaware Route 9A, which provides access to the Port of Wilmington; Delaware Route 48, which heads west from the downtown area along Lancaster Avenue; Delaware Route 52, which follows Delaware Avenue and Pennsylvania Avenue northwest out of the city to Kennett Pike; and Delaware Route 202, which follows Concord Avenue through the northern part of the city to connect to US 202 at Concord Pike.
In Wilmington, streets are laid out in a grid, with north–south streets named and east–west streets north of Lancaster Avenue/Front Street numbered from 2nd Street and increasing to the north, while east–west streets south of Lancaster Avenue/Front Street are named. Lancaster Avenue/Front Street serves as the divider between north and south while Market Street serves as the divider between east and west. There are 34 red light cameras in the city of Wilmington situated at 31 intersections. Parking in downtown Wilmington is regulated by on-street parking meters along with commercial parking lots and parking garages operated by the Wilmington Parking Authority, Colonial Parking, and SP Plus Corporation.
Wilmington is served by the Joseph R. Biden Jr. Wilmington Rail Station, with frequent service between Boston, Massachusetts, and Washington, D.C., via Amtrak's Northeast Corridor. SEPTA Regional Rail provides frequent additional local commuter rail service to Philadelphia along the Wilmington/Newark Line. Amtrak has a major maintenance shop and yard in northeast Wilmington that maintains and rebuilds the agency's Northeast Corridor electric locomotive fleet. The Amtrak Training Facility is also located in Wilmington, as well as Amtrak's Consolidated National Operations Center (CNOC).
Two freight railroads, CSX and Norfolk Southern, also serve Wilmington. Norfolk Southern serves Wilmington along trackage rights on Amtrak's Northeast Corridor, the Shellpot Secondary line heading through the eastern part of Wilmington as a bypass of the Northeast Corridor, and the New Castle Secondary line heading south to New Castle and Porter. CSX serves Wilmington along its Philadelphia Subdivision line running between Philadelphia and Baltimore. Both CSX and Norfolk Southern have a major freight-yard in the area; CSX operates the Wilsmere Yard to the west of the city in Elsmere and Norfolk Southern operates the Edgemoor Yard to the northeast of the city in Edgemoor.
DART First State (Delaware Authority for Regional Transit) operates public bus service with approximately 30 bus lines serving the city and the surrounding suburbs as well as inter-county service to Dover, the state capital, and seasonal service to Lewes and Rehoboth Beach. Many DART First State bus routes operating in Wilmington serve Wilmington Transit Center and/or Rodney Square, the main bus transit hubs in the city. DART First State also offers RideShare Delaware, a program which links commuters looking for carpools or vanpools. In addition, the site offers transit riders, walkers or bikers a Guaranteed Ride Home in the event of a work emergency. Greyhound Lines operates interstate bus service out of the Wilmington Bus Station at the rail station.
Wilmington Airport (ILG) is located a few miles south of downtown, and offers scheduled passenger service operated by Avelo Airlines. Wilmington Airport also serves as a base for both the Delaware Army National Guard and Delaware Air National Guard. The closest major international airport is Philadelphia International Airport (PHL).
Wilmington is also served by the Port of Wilmington, a modern full-service deepwater port and marine terminal handling over 400 vessels per year with an annual import/export cargo tonnage of 5 million tons. The Port of Wilmington handles mostly international imports of fruits and vegetables, automobiles, steel, and bulk products.
Delmarva Power, a subsidiary of Exelon, provides electricity and natural gas to Wilmington. The city's Department of Public Works provides water and sewer service to Wilmington and some surrounding unincorporated areas. The city's water supply comes from the Hoopes Reservoir to the northwest of the city and from a dam along the Brandywine Creek in the city, with water mains pumping the water from these sources to facilities in the city, where the water is treated and stored or distributed to customers. The city's Department of Public Works also provides trash collection and recycling to Wilmington.
Christiana Care Health System, a health network headquartered in Wilmington, runs Wilmington Hospital on the edge of downtown Wilmington and Christiana Hospital in suburban Christiana, as well as various satellite health centers throughout the area. St. Francis Hospital, a member of Trinity Health, is located in the west end of Wilmington. The Nemours Foundation runs Nemours Children's Hospital, Delaware in North Wilmington, just outside the city proper.
The city has one of the highest per capita rates of HIV infection in the United States, with disproportionate rates of infection among African-American males. Efforts by local advocates to create needle exchange programs to reduce the spread of infection were obstructed for several years by downstate and suburban state legislators but a program was finally approved in June 2006.
Much of Wilmington's economy is based on its status as the most populous and readily accessible city in Delaware, a state that made itself attractive to corporations with business-friendly financial laws and a longstanding reputation for a fair and effective judicial system. Contributing to the economic health of the downtown and Wilmington Riverfront regions has been the presence of Wilmington Station, through which 665,000 people passed in 2009.
Wilmington has become a national financial center for the credit card industry, largely due to regulations enacted by former Governor Pierre S. du Pont IV in 1981. The Financial Center Development Act of 1981, among other things, eliminated the usury laws enacted by most states, thereby removing the cap on interest rates that banks may legally charge customers. Major credit card issuers such as Barclays Bank of Delaware (formerly Juniper Bank), are headquartered in Wilmington. The Dutch banking giant ING Groep N.V. headquartered its U.S. internet banking unit, ING Direct (now Capital One 360), in Wilmington. Wilmington Trust is headquartered in Wilmington at Rodney Square. Barclays and Capital One 360 have very large and prominent locations along the waterfront of the Christina River. In 1988, the Delaware legislature enacted a law which required a would-be acquirer to capture 85 percent of a Delaware chartered corporation's stock in a single transaction or wait three years before proceeding. This law strengthened Delaware's position as a safe haven for corporate charters during an especially turbulent time filled with hostile takeovers.
Wilmington's other notable industries include insurance (American Life Insurance Company [ALICO], Blue Cross and Blue Shield of Delaware), retail banking (including the Delaware headquarters of: Wilmington Trust (now a branch of M&T Bank, after Wilmington Trust merged with M&T in 2011), PNC Bank, Wells Fargo, JPMorgan Chase, HSBC, Citizens Bank, Wilmington Savings Fund Society, and Artisans' Bank), and legal services. A General Motors plant was closed in 2009. Wilmington is home to one Fortune 500 company, E.I. du Pont de Nemours and Company. Science and Technology are also thriving as companies such as Incyte, Chemours, Corteva, Solenis and ZipCode call Wilmington home. In addition, the city is the corporate domicile of more than 50% of the publicly traded companies in the United States, and over 60% of the Fortune 500.[citation needed]
Delaware chartered corporations rely on the state's Court of Chancery to decide legal disputes, which places legal decisions with a judge instead of a jury. The Court of Chancery, known both nationally and internationally for its speed, competence, and knowledgeable judiciary as a court of equity, is empowered to grant broad relief in the form of injunctions and restraining orders, which is of particular importance when shareholders seek to block or enjoin corporate actions such as mergers or acquisitions. The Court of Chancery, as a statewide court, may hear cases in any of the state's three counties. A dedicated-use Chancery courthouse was constructed in 2003 in Georgetown, Sussex County. It has hosted high-profile complex corporate trials such as the Disney shareholder litigation.
Because Delaware is the official state of incorporation for so many American companies, the United States Bankruptcy Court for the District of Delaware, located in Wilmington, is one of the busiest of the 94 federal bankruptcy courts located around the United States.
Delaware has among the strictest rules in the U.S. regarding out-of-state legal practice, allowing no reciprocity to lawyers who passed the bar in other states.
According to Wilmington's 2019 Comprehensive Annual Financial Report, the top employers in the city are:
Departing from earlier practices, the 2014 Comprehensive Annual Report that is currently available declined to identify the city's top employers. It is possible this information will be included, consistent with past reports, when a final version of the report is publicized as mandated by City Charter.
In terms of growth, as of 2018 the city is seeing nearly $450M worth of private investments, multi-million dollars of city infrastructure improvements, and significant improvements to their transportation infrastructure.
