Comparable rate records
The nearest comparable 2024 records to Plymouth's 322.6 violent-crime rate per 100,000 are Framingham (325.5), Barre (318.9), Freetown (326.6), Orange (317.6). 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 322.6 reported violent offenses per 100,000 residents in 2024, Plymouth ranks 46 of 317 — above 271 of the 316 other Massachusetts cities whose 2024 submission passes this site’s completeness test. That is +124.3% against the cohort median of 143.8. 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 31.7% of the 694 Part I offenses reported in Plymouth for 2024, against a median of 21.4% across comparable Massachusetts cities — a gap of 10.3 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 295.2 per 100,000 in 2020 to 322.6 in 2024 (+9.3%). The highest observed value was 363.4 in 2022 and the lowest 292.0 in 2021. Years whose submission failed the completeness test are left out of this comparison rather than plotted as change.
