FBI UCR Data Snapshot: Chelmsford, MA
Chelmsford, MA, reporting population 36,795 in 2024, recorded 45 violent crimes and 415 property crimes in the FBI Uniform Crime Reporting (UCR) Program's Table 8 city-level submissions. The city's violent crime rate works out to 122.3 per 100,000 residents, while the property crime rate reaches 1127.9 per 100,000. Combining those two rates against national benchmarks yields a composite safety grade of A (Safe), scoring 78 out of 100.
Within the violent crime count, aggravated assault accounted for 38 incidents, robbery 1, murder 0, and rape 6 in 2024. Property crime splits into larceny-theft (359), burglary (43), and motor vehicle theft (13); the FBI UCR Program tracks arson (0) as a separate offense category, so it is not included in the property crime total above. Larceny-theft and other property offenses typically dominate city crime counts, and larceny-theft leads Chelmsford's mix at 78.0% of all Part I offenses.
Against the national violent crime average, Chelmsford runs 65% below the US benchmark, and 60% below the Massachusetts statewide rate. Year-over-year, the violent crime rate rose 6.8% from 2023 to 2024, while property crime climbed 16.1%. By violent crime rate, Chelmsford ranks #65 of 186 Massachusetts cities with at least 10,000 residents. UCR figures reflect offenses reported to and submitted by local law enforcement and may undercount unreported crime.
How to read these numbers
These figures come from the FBI's Uniform Crime Reporting (UCR) program, which compiles offenses voluntarily submitted by local law enforcement agencies. Rates are expressed per 100,000 residents so a small town and a large city sit on the same scale, 50 burglaries mean something very different in a town of 2,000 than in a city of 500,000. Two caveats matter when reading any city's numbers. First, a year with missing or partial agency reporting can understate true crime, so a sudden drop sometimes reflects a reporting gap rather than a real safety gain. Second, UCR counts reported offenses, not convictions, and many crimes are never reported at all. Treat a grade as one input among several, not a final verdict on a place.
