Congressional and State Legislature maps
McHenry County now includes parts of two Congressional districts: IL-10 and IL-14. The county also includes parts of Illinois State Senate districts 26, 32 and 33, and all or part of Illinois State Representative districts 52, 63, 64, 65 and 66.
Congressional and state legislature district boundaries are redrawn every 10 years, after the Federal census, in order to rebalance them to account for changes in population. You can click on the map below to view the interactive district finder provided by the State Board of Elections.
