Why Does Illinois Have Counties?
Illinois has counties for the same reasons as other most other states. States are divided into counties so citizens can have easier access to smaller, localized government functions. The function of county governments vary widely across the United States with specific Illinois county functions perhaps varying slightly from other states.Most county level governments are responsible for paving streets and sidewalks, regulating the police and firefighters, collecting garbage, and managing public transit services. Overall, Illinois counties were created for a more personalized approach to governing smaller geographic areas of the state.
