Small-count caution
South Plainfield reported 29 violent offences in 2024 against a population of 24,605. 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 South Plainfield's 117.9 violent-crime rate per 100,000 are Franklin Township, Gloucester County (117.9), Highlands (117.9), Montclair (118.1), Winslow Township (117.2). 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 117.9 reported violent offenses per 100,000 residents in 2024, South Plainfield ranks 143 of 417 — above 274 of the 416 other New Jersey cities whose 2024 submission passes this site’s completeness test. That is +73.0% 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.
2020–2024 direction
Across 5 comparable reporting years, the rate moved from 116.2 per 100,000 in 2020 to 117.9 in 2024 (+1.4%). The highest observed value was 160.6 in 2023 and the lowest 91.9 in 2021. Years whose submission failed the completeness test are left out of this comparison rather than plotted as change.
Property counts dominate South Plainfield'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 29 reported violent incidents in a population of 24,605. 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.
