The verdict
Sea Isle City earns a C safety grade: violent crime runs 60% below the U.S. average, placing it close to the national middle for violent crime.
Based on 3 reported violent incidents in a population of 2,128. 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.
2020–2024 direction
Across 5 comparable reporting years, the rate moved from 49.5 per 100,000 in 2020 to 141.0 in 2024 (+184.6%). The highest observed value was 515.2 in 2022 and the lowest 0.0 in 2021. Years whose submission failed the completeness test are left out of this comparison rather than plotted as change.
Small-count caution
Sea Isle City reported 3 violent offences in 2024 against a population of 2,128. 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 Sea Isle City's 141.0 violent-crime rate per 100,000 are Clayton (141.4), West Orange (139.8), South Amboy (139.1), Lakehurst (143.3). 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 141.0 reported violent offenses per 100,000 residents in 2024, Sea Isle City ranks 115 of 417 — above 302 of the 416 other New Jersey cities whose 2024 submission passes this site’s completeness test. That is +106.9% 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.
Offense mix
Violent offenses are 4.0% of the 75 Part I offenses reported in Sea Isle City for 2024, against a median of 7.2% across comparable New Jersey cities — a gap of 3.2 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 Sea Isle City'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 2,128. 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.
On a small municipal row, small denominators make rates sensitive to a handful of incidents. Figures are reported totals, not neighbourhood advice.
