The 11th congressional district of Illinois is represented by Democrat Bill Foster.
From 1865 to 1867, the district included Bureau, LaSalle, Livingston and Woodford counties.[3] From 1901 until 1947 the 11th congressional district included Kane, DuPage, McHenry and Will Counties. Following the Congressional Apportionment Act of 1947, the district covered a portion of Cook County and the far northwest side of Chicago roughly centered on Norwood Park.[4] The district was not changed by 1951's redistricting.[5] In 1961, the district was widened westward to the Des Plaines River and east into parts of Lincoln Square.[6] The district covered the northwest side of Chicago until the early 1990s when it moved closer to its current area, encompassing most of LaSalle and Grundy Counties, the southern part of Will County, the northern part of Kankakee County and a small portion of southeastern Cook County along the Indiana state line.[7] The Illinois Congressional Reapportionment Act of 2001 (10 ILCS 76) defined its boundaries following the 2000 U.S. census.
Following the 2010 U.S. census the district includes Joliet in Will County, parts of Naperville in southern DuPage County, and Aurora in Kane County. It includes the Argonne National Laboratory. The congressional district covers parts of Cook, Du Page, Kane, Kendall and Will counties, as of the 2011 redistricting which followed the 2010 census. All or parts of Aurora, Bolingbrook, Darien, Joliet, Montgomery, Naperville, Lisle, Downers Grove, New Lenox, Shorewood and Woodridge are included.[8] The representatives for these districts were elected in the 2012 primary and general elections, and the boundaries became effective on January 3, 2013.
