Illinois Congressional Districts Wall Map
This map covers all 17 Illinois congressional districts with the boundaries in effect for the 2026 election and the 120th Congress seated 2027 through 2029. Map Shop designs and publishes this map in house, so the lines reflect current redistricting data rather than a recycled cycle.
Color coding is non-partisan — no red, no blue, just readable district separation you can point at in a briefing without anyone reading intent into it. Campaign staff use it for field planning and voter targeting, government affairs teams for district outreach and policy research, and sales managers for carving service territories along district lines. Schools and libraries hang it for civics instruction.
