Position in the state cohort
At 574.6 reported violent offenses per 100,000 residents in 2024, Lynn ranks 12 of 317 — above 305 of the 316 other Massachusetts cities whose 2024 submission passes this site’s completeness test. That is +299.6% 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.
Comparable rate records
The nearest comparable 2024 records to Lynn's 574.6 violent-crime rate per 100,000 are Chicopee (566.6), Brockton (599.2), Lowell (532.5), Boston (627.9). 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 32.9% of the 1,801 Part I offenses reported in Lynn for 2024, against a median of 21.4% across comparable Massachusetts cities — a gap of 11.5 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 443.6 per 100,000 in 2020 to 574.6 in 2024 (+29.5%). The highest observed value was 655.1 in 2022 and the lowest 443.6 in 2020. Years whose submission failed the completeness test are left out of this comparison rather than plotted as change.
Property-offense composition
Larceny-theft is 67.0% of reported property offenses in Lynn, against a cohort median of 78.1%. The remainder is burglary (209) and motor vehicle theft (190). Composition differences of this size usually track what kinds of places and property are present in a jurisdiction.
Property counts dominate Lynn'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.
On a large city row, these are citywide reported offense totals - not neighbourhood advice. Conditions vary by place and time; reporting rates differ across jurisdictions.
