Dauphin County (/ˈdɔːfɪn/; Pennsylvania Dutch: Daffin Kaundi) is a county in the Commonwealth of Pennsylvania. As of the 2020 census, the population was 286,401. The county seat is Harrisburg, Pennsylvania's state capital and ninth-most populous city. The county was created on March 4, 1785, from part of Lancaster County and was named after Louis Joseph, Dauphin of France, the first son of King Louis XVI. The county is part of the South Central Pennsylvania region of the state.

Dauphin County is included in the Harrisburg–Carlisle Metropolitan Statistical Area.

Located within the county is Three Mile Island Nuclear Generating Station, site of the 1979 nuclear core meltdown. The nuclear power plant closed in 2019.

The inclusion of temperature numbers for the past decade shows some lower-lying areas, including Harrisburg, to have a humid subtropical climate (Cfa.) The hardiness zone is 7a except in some higher northern areas where it is 6b and a few very small areas along the river below the city including the airport where it is 7b.

2020 census

Amish community

Dauphin County is home to an Amish community that resides in the Lykens Valley in the northern part of the county, consisting of eight church districts. The community was settled by Amish from Lancaster County seeking cheaper land.

Metropolitan Statistical Area

The United States Office of Management and Budget has designated Dauphin County as the Harrisburg-Carlisle, PA Metropolitan Statistical Area (MSA). As of the 2010 U.S. Census the metropolitan area ranked 5th most populous in the State of Pennsylvania and the 96th most populous in the United States with a population of 549,475. Dauphin County is also a part of the larger Harrisburg–York–Lebanon combined statistical area (CSA), which combines the populations of Dauphin County as well as Adams, Cumberland, Lebanon, Perry and York Counties in Pennsylvania. The combined statistical area ranked the 5th most populous in Pennsylvania and 43rd most populous in the nation with a population of 1,219,422.

Politics and government

Dauphin County was historically a Republican stronghold, like most of south-central Pennsylvania. It was long one of the more conservative urban counties in the nation, having only supported a Democrat for president twice from 1880 to 2004. The only breaks in this trend were in 1936 and 1964, which were national 400-electoral vote Democratic landslides.

However, there has been a decided shift toward the Democrats in national and statewide elections in recent years. This culminated when the Democrats overtook the Republicans in countywide registration during the summer of 2008.

Bob Casey Jr. carried the county in the 2006 Senate election when he unseated Rick Santorum. According to the Dauphin County Board of Elections, in 2008 Barack Obama became the first Democratic presidential candidate to carry Dauphin County since 1964, receiving 9.0% more of the vote than John McCain. It was also only the third time Dauphin County had supported a Democrat for president since 1936. Obama won Dauphin with a slightly reduced majority in 2012, while Hillary Clinton won it with a narrow plurality in 2016. It is now the only blue county in the traditionally powerfully Republican Susquehanna Valley.

In 2023, with the election of newcomer Justin Douglas to join George Hartwick, III, the Democrats took a majority on the Board of County Commissioners for the first time in nearly 100 years. That same year, Democrat Bridget Whitley was elected Clerk of Courts as the first Democratic row officer, while the remaining row offices remained Republican. Three of the state house seats are held by Democrats. Republicans control two state house seats as well as one of the two state senate seats and the congressional seat. Most local elected officials are also Republican, by a margin of 3 to 1. This is because most of the Democratic gains have been in already heavily Democratic Harrisburg, which has had a Democratic mayor since 1982 and has been represented in the state house by a Democrat since 1975. In contrast, the suburbs and rural areas are among the most Republican areas of Pennsylvania.

Voter registration

As of July 29, 2024, 44.0% of registered voters in the county were Democrats, 38.6% Republicans, 13.3% non-affiliated, and 4.1% other party.
