Data updated 2026-09-05
Riverdale, NJ is safer than most U.S. cities, and earns a B PlainCrime safety grade, where violent crime runs 80% below the U.S. average
According to the FBI Uniform Crime Reporting (UCR) Program for 2024, Riverdale, NJ shows violent crime at 71.5 per 100,000 residents and property crime at 3,002.9 per 100,000. Violent crime runs 80% below the U.S. average. PlainCrime assigns grade B from those rates. Figures are voluntary agency submissions joined to population denominators; incomplete coverage can move the number.
Small-count caution
Riverdale reported 3 violent offences in 2024 against a population of 4,196. 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 Riverdale's 71.5 violent-crime rate per 100,000 are Harrison Township (70.6), East Windsor Township (72.5), Milltown (70.4), Somerville (72.7). 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 95.2% of reported property offenses in Riverdale, against a cohort median of 82.0%. The remainder is burglary (3) and motor vehicle theft (3). Composition differences of this size usually track what kinds of places and property are present in a jurisdiction.
Offense mix
Violent offenses are 2.3% of the 129 Part I offenses reported in Riverdale for 2024, against a median of 7.2% across comparable New Jersey cities — a gap of 4.9 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.
Position in the state cohort
At 71.5 reported violent offenses per 100,000 residents in 2024, Riverdale ranks 203 of 417 — above 214 of the 416 other New Jersey cities whose 2024 submission passes this site’s completeness test. That is +4.9% 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 Riverdale'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 3 reported violent incidents in a population of 4,196. 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-city offense counts above are voluntary UCR submissions, not neighbourhood advice. Year-to-year swings can look large when the population base is modest.
