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.
Weather is a real factor too, not just crime. Illinois sits in a genuine severe thunderstorm and tornado corridor, with the highest activity typically in spring and early summer, and winters can turn harsh fast — especially near Lake Michigan, where lake-effect conditions can intensify snowfall along the Chicago shoreline. It's worth checking current weather alerts alongside crime data if you're relocating.
Illinois's flat 4.95% state income tax applies statewide, but cost of living otherwise varies enormously between Chicago's core, its suburbs, and downstate communities like Springfield. Our income calculator can help translate that gap into what you'd actually need to earn for a specific ZIP code rather than relying on statewide averages.
Some of the widest ZIP-to-ZIP safety score variation of any major U.S. city, tied to decades of differing investment across the North, South, and West Sides.
Consistently among the state's safer ZIP codes, with a suburban housing stock and lower density than the urban core.
The state capital and much of downstate Illinois show crime patterns more typical of smaller Midwestern communities than a major metro.
Heavily agricultural, lower density, and more affordable than the Chicago metro, with less severe weather exposure than the lakefront.
Crime score is one piece of the picture in a state with real tornado and winter storm exposure. Swap the ZIP for your own once you're on the tool page.
Illinois safety statistics are dominated by Chicago, but Chicago itself shows some of the widest ZIP-to-ZIP variation of any major U.S. metro. Downstate Illinois and Chicago's suburbs look very different again. Look up your specific ZIP code rather than a citywide or statewide reputation.
Based on the ZIP-level data in this tool, suburban communities in areas like Naperville and the broader DuPage County region consistently show stronger safety scores than Chicago's urban core.
Chicago's North Side, South Side, and West Side have well-documented differences in crime patterns tied to decades of differing economic investment and housing density. A single citywide crime statistic tends to obscure just how differently individual neighborhoods, and even individual ZIP codes, actually perform.
Illinois sees a real tornado and severe thunderstorm season, typically spring through early summer, along with harsh winter conditions including extreme cold and heavy snow, especially near Lake Michigan. Check the weather tool for current alerts on a specific ZIP code.
