Somerville, NJ is safer than most U.S. cities, and earns an A PlainCrime safety grade, where violent crime runs 79% below the U.S. average
According to the FBI Uniform Crime Reporting (UCR) Program for 2024, Somerville, NJ shows violent crime at 72.7 per 100,000 residents and property crime at 747.3 per 100,000. Violent crime runs 79% below the U.S. average. PlainCrime assigns grade A from those rates. Figures are voluntary agency submissions joined to population denominators; incomplete coverage can move the number.
2020–2024 direction
Across 5 comparable reporting years, the rate moved from 16.6 per 100,000 in 2020 to 72.7 in 2024 (+339.5%). The highest observed value was 78.6 in 2021 and the lowest 16.6 in 2020. Years whose submission failed the completeness test are left out of this comparison rather than plotted as change.
Small-count caution
Somerville reported 11 violent offences in 2024 against a population of 15,122. 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 Somerville's 72.7 violent-crime rate per 100,000 are East Windsor Township (72.5), Riverdale (71.5), Bordentown Township (74.2), Wallington (74.5). 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 69.9% of reported property offenses in Somerville, against a cohort median of 82.1%. The remainder is burglary (29) and motor vehicle theft (5). Composition differences of this size usually track what kinds of places and property are present in a jurisdiction.
Position in the state cohort
At 72.7 reported violent offenses per 100,000 residents in 2024, Somerville ranks 201 of 417 — above 216 of the 416 other New Jersey cities whose 2024 submission passes this site’s completeness test. That is +6.7% against the cohort median of 68.1. Cities that did not report, or that reported implausibly low totals, are excluded from this cohort rather than counted as low-crime.
Property counts dominate Somerville'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 11 reported violent incidents in a population of 15,122. 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.
