Warren, MA is higher-crime than most U.S. cities, and earns an A PlainCrime safety grade, where violent crime runs 39% below the U.S. average
According to the FBI Uniform Crime Reporting (UCR) Program for 2024, Warren, MA shows violent crime at 215.4 per 100,000 residents and property crime at 352.5 per 100,000. Violent crime runs 39% 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
Warren reported 11 violent offences in 2024 against a population of 5,106. 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 Warren's 215.4 violent-crime rate per 100,000 are Bellingham (215.5), Woburn (215.4), Kingston (216.9), Sturbridge (217.1). 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 37.9% of the 29 Part I offenses reported in Warren for 2024, against a median of 21.4% across comparable Massachusetts cities — a gap of 16.6 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 365.2 per 100,000 in 2020 to 215.4 in 2024 (-41.0%). The highest observed value was 365.2 in 2020 and the lowest 201.2 in 2022. Years whose submission failed the completeness test are left out of this comparison rather than plotted as change.
Position in the state cohort
At 215.4 reported violent offenses per 100,000 residents in 2024, Warren ranks 99 of 317 — above 218 of the 316 other Massachusetts cities whose 2024 submission passes this site’s completeness test. That is +49.8% 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.
Property counts dominate Warren'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 11 reported violent incidents in a population of 5,106. 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.
Small-city offense counts above are voluntary UCR submissions, not neighbourhood advice. Year-to-year swings can look large when the population base is modest.
