Interactive map of Delaware County, Pennsylvania

Delaware County, colloquially referred to as Delco,[2] is a county in the Commonwealth of Pennsylvania. With a population of 576,830 as of the 2020 census,[3] 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. The county is part of the Southeast region of the commonwealth.[a]

Delaware County borders Philadelphia, the nation's sixth-most populous city, to its northeast. It also is adjacent to the city-county of Philadelphia County and is included in the Philadelphia–Camden–Wilmington, PA–NJ–DE–MD metropolitan statistical area. Its county seat is Media.[4]

## History

[edit]

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 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 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

[edit]

Bartram's Covered Bridge, built 1860 west of Newtown Square, crosses Crum Creek into Chester County Newlin Mill, built 1704, on the west branch of Chester Creek, near Concordville

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.[6]

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)[7] 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.

With its location in the southeastern part of the state, Delaware County is the only county to border both Delaware and New Jersey.

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

Until the 1990s, Delaware County was regarded as a classic suburban 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 all but once from 1860 through 1988, with the exception being Lyndon Johnson's national landslide of 1964.

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. The county 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 large 21-point margins in each of his bids for president. Hillary Clinton carried it by an equally substantial 22 points in 2016. 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.

Driving the county's Democratic shift have been longstanding trends in voter registration advantage and demographics. In 1998, Republicans held a voter registration advantage of about 125,000,[19] but by 2008 that advantage had shrunk to under 20,000 voters.[20] As of the November 2021 election, Democrats enjoyed a voter registration advantage of 50,000. Propelling and compounding the voter registration shift has been a change in demographics in the county. Since the 2000 Census, the White population of the county has decreased from 80.3% to 68.5% as of the 2020 Census, while, the Black population has risen from 14.5% to 22.7%, driven by the gentrification of Philadelphia and University City neighborhood and rapid demographic shift in Upper Darby.[21][22][23] Further increasing the shift has been the change in education level demographics in the county, as voters have become more college educated and white collar (and, in turn, less blue collar) over the past few decades.

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).[24]

After the election of Donald Trump in 2016, the county rapidly shifted blue as a result of increased Democratic turnout and less enthusiasm from often less conservative suburban Republicans. In the 2019 elections for the Delaware County Council, Democrats swept the board and elected Monica Taylor, Elaine P. Schaefer, and Christine Reuther, gaining control of the county Council for the first time since the Civil War.[25] This was the first time in history that the county had an all-Democratic Council.[26]

As of 2020, 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.[27] 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.[28]

### County row officers

[edit]

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.[31]
