This district spans the lands of Cook County. Its borders embrace all or part of Broadview, Bellwood, Chicago, Forest Park, Hillside, Oak Park, La Grange Park, Maywood, and Westchester, shaped by the great redrawing that followed the Census of 2020.

The Seventh is a land where history was forged. Within its borders lies Bronzeville, the legendary Black Metropolis, where African American culture, business, and community flourished during the Great Migration. Here, countless dreams took root, leaving a legacy that endures to this day.

The district also guards the home of Oscar Stanton De Priest, the first African American ever elected to Congress from a northern state. His house remains a monument to a landmark victory in the nation's history.

Many great treasures can be found across the Seventh. The Adler Planetarium and Astronomy Museum, opened in 1930, became the first planetarium in the Western Hemisphere, inviting generations of explorers to chart the stars. The Art Institute of Chicago, founded in 1879, stands among the oldest and greatest museums in the nation, preserving masterpieces from across the ages.

Beyond these landmarks lies the Ridgeland–Oak Park Historic District, where streets are lined with grand Prairie School and Victorian architecture. Together, these places make the Seventh a realm of history, culture, and enduring legacy.
