The map below identifies the 12 regions Illinois was divided into. This was done to provide assigned Regional Intermediaries (RIs) with manageable sections of the state to conduct their Census outreach, and to allow them to tailor messaging and activities to specific Hard-to-Count (HTC) communities and counties.
