The verdict
Glen Rock earns an A+ safety grade: violent crime runs 95% below the U.S. average, placing it among the safest cities in the country.
Based on 2 reported violent incidents in a population of 12,331. 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.
Small-count caution
Glen Rock reported 2 violent offences in 2024 against a population of 12,331. 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.
2020–2024 direction
Across 5 comparable reporting years, the rate moved from 8.5 per 100,000 in 2020 to 16.2 in 2024 (+89.8%). The highest observed value was 33.3 in 2022 and the lowest 8.2 in 2021. Years whose submission failed the completeness test are left out of this comparison rather than plotted as change.
Comparable rate records
The nearest comparable 2024 records to Glen Rock's 16.2 violent-crime rate per 100,000 are River Edge (16.3), Westfield (16.1), Dumont (16.0), Roseland (16.0). 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.
Position in the state cohort
At 16.2 reported violent offenses per 100,000 residents in 2024, Glen Rock ranks 349 of 417 — above 68 of the 416 other New Jersey cities whose 2024 submission passes this site’s completeness test. That is -76.3% against the cohort median of 68.5. Cities that did not report, or that reported implausibly low totals, are excluded from this cohort rather than counted as low-crime.
Offense mix
Violent offenses are 2.6% of the 78 Part I offenses reported in Glen Rock for 2024, against a median of 7.2% across comparable New Jersey cities — a gap of 4.7 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.
Property counts dominate Glen Rock'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.
