Lemont, IL Crime Map

Lemont, IL Safety Overview: An A-Rated Community

With a population of 17,131 and an overall crime grade of A, Lemont, Illinois ranks among the safest communities in the Chicago metropolitan area. Every single analyzed neighborhood — 100% of them — earned an A-level grade, meaning residents across the entire village enjoy a consistently low-crime environment. That kind of uniformity is rare, and it reflects the community's strong socioeconomic foundation, including a median household income of $114,509 and a poverty rate of just 5.1%.

Neighborhood-Level Safety in Lemont

The Argonne National Laboratory area is the one neighborhood for which granular data is available, and it holds a grade of A-, with a local population of 3,327 and a median income of $102,990. While it appears in both the safest and the relatively higher-crime lists — a reflection of how narrow the safety range truly is in Lemont — an A- still represents an exceptionally low-crime environment by any standard. There are no D- or F-rated areas in this village, and the absence of any grade below A underscores just how safe Lemont is compared to most Illinois communities.

Crime Grade Distribution Across Lemont

One hundred percent of Lemont's analyzed neighborhoods earned an A grade, with zero neighborhoods scoring B, C, D, or F. That means the combined share of safe neighborhoods — those rated A or B — is 100%. This distribution is not typical. Most cities of comparable size show at least some variation, with pockets of elevated risk pulling down the overall profile. Lemont's consistency points to well-maintained infrastructure, active code enforcement, and a community that takes neighborhood watch and civic engagement seriously.

Property Crime vs. Violent Crime in Lemont

Like most low-density suburban communities with an unemployment rate of 3.7% and a median home value of $374,472, Lemont's crime profile skews heavily toward minor property incidents rather than violent offenses. Opportunistic property crimes — such as vehicle break-ins or package theft — are far more likely to occur here than assaults or robberies. The low poverty rate of 5.1% and the relatively modest population density of 794 people per square mile reduce the conditions that typically drive violent crime upward. Residents are statistically far more likely to encounter a nuisance property incident than any form of violent crime, and even those incidents remain infrequent given the A-level rating.
