The District's boundaries in the 2018 elections that will be effective January 3, 2019

Pennsylvania's 18th congressional district includes parts of Greene, Washington, Allegheny, and Westmoreland counties. The district is represented by Conor Lamb, who was elected March 13, 2018.^[4]

The district is concentrated in the southern suburbs of Pittsburgh. It is predominantly white, although it contains a diverse range of suburbs. It is drawn in such a way that in some locations, neighborhoods and even streets are split between the 18th and the neighboring 12th and 14th districts. In parts of the eastern portion of the district, one side of the street is in the 12th while the other side is in the 18th. In the west, one side of the street is in the 14th while the other side is in the 18th.

Although there are 35,000 more^[5]Democrats in the district than Republicans, the district has trended increasingly Republican since the mid-1990s; most of the district's state legislators are Republicans. The district is home to many large coal mines and the energy industry is an important employer. The western part of the district contains some rural regions of Washington County, as well as the very wealthy suburbs in the northern part of that county, which tends to be more Republican than the part contained in the neighboring 9th District. The district also contains many of Allegheny County's southern suburbs of Pittsburgh, which range from traditionally wealthy areas such as Mount Lebanon and Upper St. Clair to middle-class communities such as Bethel Park and Scott Township and working-class labor towns such as Elizabeth.

The district skews older and has the second-oldest electorate in the state.^[6]

The district winds along the eastern suburbs at the edge of Allegheny County, including most of the large suburban commercial center of Monroeville, and in western Westmoreland County. Central Westmoreland County, including the city of Greensburg, is also part of the district. It also contains the rural foothills of the county at the district's eastern end. Westmoreland County has become a major Republican stronghold.

The Supreme Court of Pennsylvania ruled that the district map violated the state constitution and redrew it in February 2018. The 18th and 14th districts will swap names and have their boundaries adjusted for the 2018 elections (after March's special election) and thereafter.^[7]^[8]

Historically, the current district covers much of the area that was the center of the Whiskey Rebellion of the 1790s.
