How the Crime Grade is calculated
- Source: FBI Uniform Crime Reporting via the Crime Data Explorer. Agency-level data, pulled directly. No third-party aggregators, no proprietary score.
- Metric: Violent crime rate per 100,000 residents (murder + rape + robbery + aggravated assault), most recent fully-reported year.
- National decile: Dennis's rate placed against all FBI-reporting U.S. cities with population ≥ 25,000. 1 = safest.
- State decile: Same calculation restricted to Massachusetts cities with population ≥ 10,000.
- Letter grade: 1–3 = A · 4–5 = B · 6–7 = C · 8 = D · 9–10 = F.
- Refresh: Twice a year. The FBI typically releases the prior year's full data each September.
- Limits: The FBI relies on local agency reporting. Rates reflect what was reported, not what occurred.
