About IL04

Illinois’ 4th Congressional District covers Chicago’s southwest and northwest sides, including the neighborhoods of Brighton Park, Gage Park, McKinley Park, North Lawndale, Little Village, Humboldt Park, Logan Square, Avondale, and Belmont Cragin. It also encompasses parts of several western suburbs, including Berwyn, Cicero, Melrose Park, and Riverside. IL-04 is located entirely within Cook County.

The District owes its distinctive shape to Hastert v. Board of Elections, a 1991 federal district court decision that created a Hispanic voting majority district in the Chicagoland area in response to the Voting Rights Act of 1965 and the 14th and 15th Amendments to the US Constitution.

Waves of immigrants from all over the world have come to call IL-04 home and contributed to the District’s rich culture. People born in other countries continue to settle in the area: according to 2017 estimates, almost 240,000 of the District’s 700,000 residents were born abroad, the highest portion in the Midwest.
