Swansea, MA is close to the national middle for violent crime, and earns an A PlainCrime safety grade, where violent crime runs 63% below the U.S. average
According to the FBI Uniform Crime Reporting (UCR) Program for 2024, Swansea, MA shows violent crime at 129.4 per 100,000 residents and property crime at 731.5 per 100,000. Violent crime runs 63% 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.
Small-count caution
Swansea reported 23 violent offences in 2024 against a population of 17,772. 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 Swansea's 129.4 violent-crime rate per 100,000 are Acushnet (129.4), Warwick (129.2), West Brookfield (127.4), Wrentham (131.7). 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.
Offense mix
Violent offenses are 15.0% of the 153 Part I offenses reported in Swansea for 2024, against a median of 21.5% across comparable Massachusetts cities — a gap of 6.5 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.
2020–2024 direction
Across 5 comparable reporting years, the rate moved from 112.7 per 100,000 in 2020 to 129.4 in 2024 (+14.8%). The highest observed value was 149.0 in 2022 and the lowest 112.7 in 2020. Years whose submission failed the completeness test are left out of this comparison rather than plotted as change.
Position in the state cohort
At 129.4 reported violent offenses per 100,000 residents in 2024, Swansea ranks 171 of 317 — above 146 of the 316 other Massachusetts cities whose 2024 submission passes this site’s completeness test. That is -10.8% against the cohort median of 145.1. 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 Swansea'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 23 reported violent incidents in a population of 17,772. 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.
