Delaware County, colloquially referred to as Delco, is a county located in the U.S. state of Pennsylvania. With a population of 562,960, it is the fifth most populous county in Pennsylvania, and the third smallest in area. The county was created on September 26, 1789, from part of Chester County and named for the Delaware River.

Delaware County is adjacent to the city-county of Philadelphia and is included in the Philadelphia–Camden–Wilmington, PA–NJ–DE–MD Metropolitan Statistical Area. Delaware County is the only county covered in its entirety by area codes 610 and 484.

Delaware County lies in the river and bay drainage area named "Delaware" in honor of Thomas West, 3rd Baron De La Warr, Governor of the nearby English colony of Virginia. The land was "discovered" and explored by Henry Hudson in 1609, and over the next several decades it was variously claimed and settled by the Swedes, the Dutch, and the English. Its original human inhabitants were the Lenni-Lenape tribe of American Indians.

Once the Dutch were defeated and the extent of New York was determined, King Charles II of England made his grant to William Penn in order to found the colony which came to be named Pennsylvania. Penn divided his colony into three counties: Bucks, Philadelphia, and Chester. The riverfront land south of Philadelphia, being the most accessible, was quickly granted and settled. In 1789, the southeastern portion of Chester County was divided from the rest and named Delaware County for the Delaware River.


According to the U.S. Census Bureau, the county has a total area of 191 square miles (490 km2), of which 184 square miles (480 km2) is land and 6.8 square miles (18 km2) (3.5%) is water. It is the third-smallest county in Pennsylvania by area.

Delaware County is roughly diamond- or kite-shaped, with the four sides formed by the Chester County boundary to the northwest, the boundary with the state of Delaware (a portion of the "Twelve Mile Circle") to the southwest, the Delaware River (forming the border with the state of New Jersey to the southeast, and the city of Philadelphia and Montgomery County to the east and northeast.

The lowest point in the state of Pennsylvania is located on the Delaware River in Marcus Hook in Delaware County, where it flows out of Pennsylvania and into Delaware. The highest point in Delaware County is 500 feet at two points southeast of Wyola in Newtown Township [1].

Waterways in Delaware County generally flow in a southward direction and ultimately drain into the Delaware River. The waterways are, from west to east: the Brandywine River (forming a portion of the county's western boundary with Chester County), Chester Creek, Ridley Creek, Crum Creek, Muckinipates Creek, Darby Creek and Cobbs Creek (forming a portion of the county's eastern boundary with Philadelphia). Crum Creek was dammed in 1931 near Pennsylvania Route 252 to fill Springton Lake (also known as Geist Reservoir), an approximately 391-acre (1.58 km2) drinking water reservoir maintained by Aqua America, the county's largest lake.

    Politics and government

    As of November 2008, there are 406,352 registered voters in Delaware County.

  • Republican: 190,716 (46.93%)
  • Democratic: 172,405 (42.43%)
  • Other Parties: 43,231 (10.64%)
  • Politically, Delaware County traditionally voted Republican. It voted for the Republican candidate in nearly every election from 1854 through 1988, with exceptions including the 1964 presidential election. As was the case in most of the Philadelphia suburbs, however, the brand of Republicanism that prevailed in the area was traditionally a moderate one. It has operated under a home-rule charter with five at-large councilmembers since 1972. Republicans remain in control of many county council seats and row offices.

    In recent elections, however, Delaware County has been trending Democratic and the Republican registration edge has declined rapidly from over twice as many voters as Democrats had in 2002. It narrowly voted for Bill Clinton in 1992, but has gone Democratic in every Presidential election since then by 10 points or more by progressively-increasing margins. In the 2004 election Democratic presidential candidate John Kerry won the county by 14 points. In the 2004 US Senate election, Republican Arlen Specter defeated Joe Hoeffel but Democrat Bob Casey, Jr. defeated Rick Santorum in the 2006 Senate election. In the 2008 presidential election, Democratic Senator Barack Obama defeated Republican Senator John McCain resoundingly, by over 21 points. All three Democratic state row office candidates also carried it in 2008.

    In 2016, Delaware County elected all Democrats in the elections except Republican Patrick Meehan (U.S. Representative).

    Most of Delaware County is located in the state's 7th congressional district, represented by Republican Pat Meehan. The district had been held for 20 years by Republican Curt Weldon until he was ousted by Joe Sestak, a retired admiral, in the 2006 U.S. House of Representatives election. Also in the 2006 election, Democrat Bryan Lentz unseated Republican incumbent State Representative Tom Gannon in the 161st House district. In 2010 Sestak ran for the senate seat vacated by Arlen Specter and was replaced by Meehan, defeating Lentz, who ran as the Democrat. Lentz was replaced in the State House by Joe Hackett, a Republican. A small portion of the county, mostly consisting of the areas around Chester, Yeadon and Darby, is in the Philadelphia-based 1st district, represented by Democrat Bob Brady.


    The George W. Hill Correctional Facility (Delaware County Prison) is located in Thornbury Township. The jail houses pre-trial inmates and convicted persons who serve county sentences of two years less one day.
