Its county seat is Media.[4] Until 1850, Chester was the county seat of Delaware County and, before that, of Chester County.

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.

History
Map of the early settlements of Delaware County, Pennsylvania

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 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.

Geography
Bartram's Covered Bridge, built 1860 west of Newtown Square, crosses Crum Creek into Chester County.

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.[5] 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 .

Newlin Mill, built 1704, on the west branch of Chester Creek, near Concordville.

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), Naaman's Creek, Stoney Creek, 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)[6] drinking water reservoir maintained by Aqua America, the county's largest lake.

The Trainer Refinery and the Port of Chester are located along the shores of the Delaware River.

Adjacent counties

Delaware County is one of four counties in the United States to border a state with which it shares the same name (the other three are Nevada County, California, Texas County, Oklahoma, and Ohio County, West Virginia).

The county has operated under a home-rule charter with five at-large council-members since 1972.

In November 2019, there was a historically significant election held that resulted in the Democratic Party taking total control of the county council for the first time since the Civil War.[14] Another notable election result was that of Nusrat Rashid, who now enjoys the accolades of being the first African-American female Common Pleas judge in the county, as well as being the first Muslim to be elected into any judicial position in the entire Commonwealth.[15] Also of note was the election of Jack Stollsteimer to the position of District Attorney, representing the first time a Democrat has ever had this position in the county.[16] This major change has been colloquially referred to as "The Blue Wave."[17]

As of June 2017, there were 391,683 registered voters in Delaware County.[13]

  • Democratic: 178,788 (45.65%)
  • Republican: 164,106 (41.88%)
  • No Affiliation: 25,892 (6.61%)
  • Other Parties: 22,897 (5.85%)

Until recent years, Delaware County was regarded as a strongly Republican county. The Delaware County Republican [political machine]] was controlled by William McClure and his son John J. McClure from 1875 to 1965.[18] Delaware County voted for the Republican candidate in nearly every election from 1854 through 1988, one of the few exceptions being Lyndon Johnson's national landslide of 1964. As a measure of how Republican the county was, Franklin Roosevelt was completely shut out in all four of his successful campaigns for president. Even in his 46-state landslide victory of 1936, Roosevelt only got 45 percent of Delaware County's vote.

In 1992, however, the county swung from a 21-point win for George H. W. Bush to a narrow one-point win for Bill Clinton, who became only the second Democrat to win the county in the 20th century. Clinton won it just under 10 points in 1996, coming up just short of a majority. It 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. Barack Obama won it by resounding 21-point margins in each of his bids for president. Hillary Clinton carried it by 22 points in 2016. Clinton turned in her second-best performance in the state, behind only Philadelphia, thus cementing Delaware County's status as one of the most Democratic suburban counties in the nation. Underlining this, Joe Biden carried it in 2020 with 62 percent of the vote, his second-strongest performance in Pennsylvania. Donald Trump turned in the worst showing for a Republican in the county in over 160 years.

While the longstanding Republican registration edge has been erased, Republicans still remain competitive with Democrats at the state and local level. Most Republicans from the county tend to be fiscally conservative and socially moderate, as is the case with Republicans from most suburban Philadelphia counties. 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. All three Democratic state row office candidates carried it in 2008.

In 2016, Delaware County elected all Democrats in national office elections except Republican Patrick Meehan (U.S. Representative).[19]

All of Delaware County is located in the state's 5th congressional district, represented by Democrat Mary Gay Scanlon. Prior to 2019, most of Delaware County had been in the 7th congressional district. 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 Republican Pat Meehan, who defeated Lentz, the Democratic candidate. Lentz was replaced in the State House by Joe Hackett, a Republican. Meehan represented the 7th district until his resignation on April 27, 2018.[20] Before it was thrown out by a Pennsylvania Supreme Court decision in 2018, the 7th Congressional District had been regarded one of the most irregularly drawn districts in the nation.[21]

In the 2019 elections for the Delaware County Council, Republicans John McBlain and Colleen Morrone had served two terms and were not eligible for a third. Michael Culp, the council's third Republican, chose not to run. After a campaign described as having a good share of mud-throwing,[22] Democrats swept the board and elected Monica Taylor, Elaine P. Schaefer, and Christine Reuther. This was the first time in history that the county had an all-Democratic county council.[23]

County row officers

Row officers, a term unique to Pennsylvania, are a conglomeration of elected officials defined by Article IX, Section 4 of the Pennsylvania Constitution. This unit of officers includes the position of controller, District Attorney, treasurer, sheriff, register of wills, recorder of deeds, prothonotaries, clerks of the court, and the coroner. It is thought that this term originated because these positions were arranged in a row on a typical ballot.[25]

Corrections

The George W. Hill Correctional Facility (Delaware County Prison) is located in Thornbury Township.[26][27] The jail houses pre-trial inmates and convicted persons who are serving sentences of no longer than two years less one day.[27] It is operated by the for-profit prison corporation GEO Group, of Boca Raton, Florida. It is the only privately operated county-level correctional facility in Pennsylvania, although there are plans for it to be deprivatized as early as December 31, 2020.[28][29]
