2020–2024 direction
Across 5 comparable reporting years, the rate moved from 31.9 per 100,000 in 2020 to 272.1 in 2024 (+754.2%). The highest observed value was 272.1 in 2024 and the lowest 31.9 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 Dedham's 272.1 violent-crime rate per 100,000 are Bourne (274.6), Plainville (268.6), Nahant (268.5), Adams (276.8). 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 272.1 reported violent offenses per 100,000 residents in 2024, Dedham ranks 67 of 317 — above 250 of the 316 other Massachusetts cities whose 2024 submission passes this site’s completeness test. That is +89.2% 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 17.0% of the 405 Part I offenses reported in Dedham for 2024, against a median of 21.5% across comparable Massachusetts cities — a gap of 4.5 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.
Property counts dominate Dedham'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.
