Illinois is a major Midwestern state. Look up safety scores and crime statistics for ZIP codes across Illinois including Chicago and Springfield. Click any ZIP code to see the full safety report.
Illinois's safety statistics are heavily influenced by Chicago, the state's dominant metro area and third-largest city in the country. Chicago's well-documented variation between North Side, South Side, and West Side neighborhoods means the city alone shows some of the widest safety score ranges of any major U.S. metro, while downstate Illinois cities like Springfield show patterns more typical of smaller Midwestern communities.
Suburban Chicago communities, particularly in areas like Naperville and the broader DuPage County region, consistently rank among the safer ZIP codes in the state. When researching Illinois safety data, it's important to recognize how much Chicago's internal variation can skew perceptions of the city and state as a whole.
