FBI UCR Data Snapshot: Chelsea, MA
Chelsea, MA, reporting population 38,307 in 2024, recorded 375 violent crimes and 550 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 978.9 per 100,000 residents, while the property crime rate reaches 1435.8 per 100,000. Combining those two rates against national benchmarks yields a composite safety grade of F (High Risk), scoring 17 out of 100.
Within the violent crime count, aggravated assault accounted for 296 incidents, robbery 46, murder 2, and rape 31 in 2024. Property crime splits into larceny-theft (441), burglary (57), and motor vehicle theft (52); the FBI UCR Program tracks arson (3) 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 Chelsea's mix at 47.7% of all Part I offenses.
Against the national violent crime average, Chelsea runs 178% above the US benchmark, and 217% above the Massachusetts statewide rate. Year-over-year, the violent crime rate rose 0.9% from 2023 to 2024, while property crime declined 12%. By violent crime rate, Chelsea ranks #184 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.
