The 18th congressional district of Illinois covered central and western Illinois, including all of Jacksonville and Quincy and parts of Bloomington, Peoria, and Springfield. It is currently represented by Republican Darin LaHood, who took office in September 2015 following a special election.^[4]

Republican Aaron Schock previously represented the district from January 2009 until his resignation in March, 2015.^[5] Darin LaHood is the son of Schock's predecessor, Ray LaHood, and was reelected in 2016, 2018, and 2020.

Abraham Lincoln served much of the area that now lies within the 18th district for a single term; it was numbered as the 7th district at the time. It also contains most of the territory that was represented by future United States Senate Minority Leader Everett Dirksen (1933-1949, when it was the 16th district) and longtime House Minority Leader Bob Michel (1957-1995).

From 1949 to 2015, the district was always represented by an attendee or graduate of Bradley University. Due to reapportionment after the 2020 U.S. census, the 18th district was eliminated ahead of the 2022 elections.

2011 redistricting

The district covers parts of McLean, Peoria, Sangamon, Stark and Tazewell counties, and all of Adams, Brown, Cass, Hancock, Logan, Marshall, Mason, McDonough, Menard, Morgan, Pike, Schuyler, Scott and Woodford counties, as of the 2011 redistricting which followed the 2010 census. All or parts of Bloomington, Chatham, Jacksonville, Lincoln, Macomb, Morton, Normal, Peoria, Quincy and Springfield are included.^[6] The representatives for these districts were elected in the 2012 primary and general elections, and the boundaries became effective on January 5, 2013.

Future

Due to Illinois losing population in the 2020 United States census, the district will be eliminated in January 2023.^[7]
