Representatives from organizations in Chicago’s South Side called for more public input and offered warnings Thursday about the potential for minority groups to be undercounted if lawmakers don’t use decennial Census data during the redistricting process.

Similar to what other witnesses said during the first four Senate redistricting hearings, members of the Senate Redistricting Chicago South Subcommittee listened to testimony from seven witnesses who expressed desires to improve public participation while making a host of recommendations on how to bolster engagement.
