From 2003 to 2013 the district included suburbs ofPittsburgh as well asBeaver County,Lawrence County, andMercer County. The district had a slightDemocratic registration edge, although it had voted for Republicans in several federal elections over the 2000s decade, including for PresidentGeorge W. Bush in 2000 and 2004, as well asLynn Swann for governor in 2006. The heart of the district was a string of mostly white and middle class suburbs.Plum andMurrysville, two large and mainly residential boroughs, are the main towns in the suburban portion of the district that lies to the east of the city. Also included were the many suburban areas that make up northernAllegheny County and southernButler County, Pennsylvania, including the larger communities ofMcCandless andFranklin Park, as well as several exclusive suburbs that have long been home to Pittsburgh's old money elite, includingFox Chapel andSewickley. The northern suburbs had a generally moderate voting populace, which trends Democratic but makes up the swing vote, especially in races for national office. Further north, the district took on a different character. The suburban areas ofBeaver County are somewhat less affluent and were heavily labor Democratic. The areas ofLawrence County andMercer County had a more rural feel, but also had a union Democrat center within the city ofNew Castle.
This district changed drastically when Pennsylvania's new districts went into effect on January 3, 2013. Due to slower population growth than the nation as a whole, Pennsylvania lost a seat in Congress in reapportionment following the2010 United States census, and this seat was effectively eliminated. Most of the 4th district was merged into a redrawn12th district, and the previous19th district was rebranded as the 4th. Thus from 2013 to 2018, the 4th district was located in south-central Pennsylvania and included all ofAdams andYork counties, as well as parts ofCumberland andDauphin counties. During this time, the district was represented by RepublicanScott Perry.
TheSupreme Court of Pennsylvania redrew the state's congressional districts in February 2018 after ruling the previous map unconstitutional due togerrymandering. The fourth district was reconfigured as a Democratic-leaning area to the northwest ofPhiladelphia for the 2018 election and representation thereafter. Geographically, it is the successor to the old13th district, which was represented at the time by DemocratBrendan Boyle. Boyle, however, opted to run in the neighboring2nd district, the geographic successor to the1st district, represented by retiring incumbentBob Brady. The bulk of Perry's representation, includingYork andHarrisburg, became part of a redrawn10th district.Gettysburg and Adams County joined a new, heavily Republican 13th district, which was the successor to the old9th district of retiring CongressmanBill Shuster. Areas to the south and east of York joinedLancaster in a redrawn, heavily Republican11th district, the successor of RepublicanLloyd Smucker's16th district.[5]
