According to the FBI Uniform Crime Reporting (UCR) Program for 2024, Watertown, MA shows violent crime at 153.3 per 100,000 residents and property crime at 1,858.7 per 100,000.

Figures are voluntary agency submissions joined to population denominators; incomplete coverage can move the number.
2020–2024 direction
Across 5 comparable reporting years, the rate moved from 85.6 per 100,000 in 2020 to 153.3 in 2024 (+79.0%). The highest observed value was 153.3 in 2024 and the lowest 85.6 in 2020. Years whose submission failed the completeness test are left out of this comparison rather than plotted as change.
Comparable rate records
The nearest comparable 2024 records to Watertown's 153.3 violent-crime rate per 100,000 are Orleans (153.1), Millbury (153.5), Royalston (152.9), Salem (152.3). 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 7.6% of the 722 Part I offenses reported in Watertown for 2024, against a median of 21.5% across comparable Massachusetts cities — a gap of 13.9 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.
Property-offense composition
Larceny-theft is 95.8% of reported property offenses in Watertown, against a cohort median of 78.1%. The remainder is burglary (19) and motor vehicle theft (9). Composition differences of this size usually track what kinds of places and property are present in a jurisdiction.
Position in the state cohort
At 153.3 reported violent offenses per 100,000 residents in 2024, Watertown ranks 147 of 317 — above 170 of the 316 other Massachusetts cities whose 2024 submission passes this site’s completeness test. That is +6.6% 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.
Property counts dominate Watertown'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.
Mid-size municipal totals above are reported offenses, not safety advice for any single block. Reporting completeness still varies by year and agency.
