Small-count caution
Lockport reported 18 violent offences in 2024 against a population of 26,668. 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 Lockport's 67.5 violent-crime rate per 100,000 are Palatine (67.2), Palos Hills (68.4), Manito (68.6), Rushville (68.9). 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.
2020–2024 direction
Across 5 comparable reporting years, the rate moved from 101.2 per 100,000 in 2020 to 67.5 in 2024 (-33.3%). The highest observed value was 101.2 in 2020 and the lowest 23.1 in 2021. Years whose submission failed the completeness test are left out of this comparison rather than plotted as change.
Position in the state cohort
At 67.5 reported violent offenses per 100,000 residents in 2024, Lockport ranks 314 of 506 — above 192 of the 505 other Illinois cities whose 2024 submission passes this site’s completeness test. That is -33.0% against the cohort median of 100.7. Cities that did not report, or that reported implausibly low totals, are excluded from this cohort rather than counted as low-crime.
Property-offense composition
Larceny-theft is 59.5% of reported property offenses in Lockport, against a cohort median of 70.3%. The remainder is burglary (58) and motor vehicle theft (6). Composition differences of this size usually track what kinds of places and property are present in a jurisdiction.
Property counts dominate Lockport's FBI UCR Table 8 municipal row. Per-100,000 rates use the reporting-year population on that row; cities that fail the completeness test stay out of rate rankings. A citywide figure rarely describes any single neighbourhood inside the municipal boundary.
Based on 18 reported violent incidents in a population of 26,668. 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.
Mid-size municipal totals above are reported offenses, not safety advice for any single block. Reporting completeness still varies by year and agency.
