The verdict
Lynnfield earns an A safety grade: violent crime runs 72% below the U.S. average, placing it safer than most U.S. cities.
Based on 13 reported violent incidents in a population of 13,298. 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 53.5 per 100,000 in 2020 to 97.8 in 2024 (+82.9%). The highest observed value was 154.0 in 2023 and the lowest 53.5 in 2020. Years whose submission failed the completeness test are left out of this comparison rather than plotted as change.
Small-count caution
Lynnfield reported 13 violent offences in 2024 against a population of 13,298. 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 Lynnfield's 97.8 violent-crime rate per 100,000 are New Braintree (98.8), Wenham (98.9), Brookline (99.8), Ashland (95.4). 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 10.2% of the 127 Part I offenses reported in Lynnfield for 2024, against a median of 21.5% across comparable Massachusetts cities — a gap of 11.3 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.
Position in the state cohort
At 97.8 reported violent offenses per 100,000 residents in 2024, Lynnfield ranks 212 of 317 — above 105 of the 316 other Massachusetts cities whose 2024 submission passes this site’s completeness test. That is -32.6% 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-offense composition
Larceny-theft is 88.6% of reported property offenses in Lynnfield, against a cohort median of 78.1%. The remainder is burglary (7) and motor vehicle theft (6). Composition differences of this size usually track what kinds of places and property are present in a jurisdiction.
Property counts dominate Lynnfield'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 13 reported violent incidents in a population of 13,298. 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.
Mid-size municipal totals above are reported offenses, not safety advice for any single block. Reporting completeness still varies by year and agency.
