Among the 863 city police departments serving 25,000–50,000 residents in the 51 states loaded so far: violent crime 1.9 per 1,000 residents a year (56% of them report less), property crime 18 per 1,000 (78% report less).
The FBI warns against ranking places with these numbers: visitors, commuters, and how each department records and reports crime all differ. Treat this as context, not a grade.
Is San Dimas safe?
Crime Radar doesn't grade towns as safe or unsafe: one number can't say what a street is like, and the FBI warns against ranking places. What these reports can say is whether San Dimas has more or fewer reported crimes than it usually does, and that its yearly rate is 19.9 per 1,000 residents against 22.8 across California.

How this works
San Dimas Police Department sends monthly counts of violent and property crime to the FBI. Crime Radar compares the newest complete three months with the same months in past years, and only calls a change when it's bigger than this department's usual ups and downs. Months with missing reports are left out, so a reporting gap never looks like a safe stretch. These are totals for everywhere the department patrols, not one street.
Not every crime reaches these numbers: in the national victim survey, about 6 in 10 serious violent crimes and 3 in 10 property crimes were reported to police in 2024 (BJS).
