Map substantially equalizes population in each district for the first time in decades

SPRINGFIELD – The Senate and House Redistricting Committees today released a proposed map of new Illinois Supreme Court boundaries to bring them into compliance with the Illinois Constitution by reflecting population shifts over the nearly 60 years since the map was last drawn in 1963. 

“This map is about equal representation in the state’s most important court,” said Rep. Lisa Hernandez, Chair of the House Redistricting Committee. “As we strive for all to be equal before the law, we must ensure we all have an equal voice in choosing those who uphold it.”

Under this proposal, the number of residents in the Second, Third, Fourth and Fifth Supreme Court districts will be substantially equalized to better reflect the population and demographic shifts that have occurred in the state of Illinois over the course of the last sixty years. Currently, population fluctuates greatly between districts. For instance, the Second District contains 3.2 million people, while the Fourth and Fifth Districts contain under 1.3 million people.

“The boundaries for Illinois Supreme Court districts have not been updated for several decades, it’s time we make changes in recognition of the population changes and demographic shifts that have taken place since the 1960s,” said Sen. Omar Aquino, Chair of the Senate Redistricting Committee. “Illinois is a very different state than it was sixty years ago, and the voters of Illinois deserve to elect members to our state’s highest court that reflect their values.”

This new map will not impact the tenure of the current Appellate and Supreme Court justices. All justices running for retention will have the right to do so in their current districts. Further, this map avoids disruption to the Judicial Branch by ensuring that the Appellate Courts can remain where they currently reside and avoid changing the compositions or boundaries of the Judicial Circuits.  

Consistent with the proposed legislative maps, this proposed map was drafted using population information from the American Community Survey’s (ACS) 5-year estimate for 2019. The ACS estimate varies by just 0.3 percent from the state’s official population count released by the U.S. Census Bureau in April.

The public has the opportunity to provide input on this proposed map at four scheduled redistricting committee hearings between the House and the Senate this week. To view the proposed map, visit or
