According to the FBI Uniform Crime Reporting (UCR) Program for 2024, Lanark, IL shows violent crime at 137.4 per 100,000 residents and property crime at 137.4 per 100,000.

Offense mix
Violent offenses are 50.0% of the 4 Part I offenses reported in Lanark for 2024, against a median of 11.2% across comparable Illinois cities — a gap of 38.8 points. Offense mix is shaped by which agencies report and how incidents are classified as well as by the underlying offenses, so it describes the reported record rather than a settled difference in conditions.
Small-count caution
Lanark reported 2 violent offences in 2024 against a population of 1,456. At this volume one additional or one fewer report moves the per-100,000 rate noticeably, so the figure is better read as a data point than as a precise measurement, and year-to-year swings here are expected.
Comparable rate records
The nearest comparable 2024 records to Lanark's 137.4 violent-crime rate per 100,000 are Altamont (137.7), Elwood (136.9), White Hall (137.8), McLean (137.9). These are same-year agency submissions that pass the same completeness screen, not a claim that the cities have identical conditions. They make the cohort position above checkable against named records instead of a generic state average.
Property-offense composition
Larceny-theft is 50.0% of reported property offenses in Lanark, against a cohort median of 70.3%. The remainder is burglary (1) and motor vehicle theft (0). Composition differences of this size usually track what kinds of places and property are present in a jurisdiction.
Position in the state cohort
At 137.4 reported violent offenses per 100,000 residents in 2024, Lanark ranks 210 of 506 — above 296 of the 505 other Illinois cities whose 2024 submission passes this site’s completeness test. That is +37.8% against the cohort median of 99.7. Cities that did not report, or that reported implausibly low totals, are excluded from this cohort rather than counted as low-crime.
Lanark's FBI UCR Table 8 municipal row keeps violent and property totals in a closer balance. Per-100,000 rates use the reporting-year population on that row; incomplete reporters stay out of rate rankings. A citywide figure rarely describes any single neighbourhood inside the municipal boundary.
Based on 2 reported violent incidents in a population of 1,456. At this volume, one additional or one fewer report can shift the rate and letter grade noticeably; small-city crime counts are inherently more volatile year to year than large-city counts, so treat this grade as a data point, not a precise ranking.
On a small municipal row, small denominators make rates sensitive to a handful of incidents. Figures are reported totals, not neighbourhood advice.
