Written from the FBI data on this page. County and state agency figures cover their whole patrol area, not just this town, so they can’t be turned into a rate.
Diablo is covered by the county
Diablo has no police department of its own in the FBI’s data. Calls here most likely go to the Contra Costa County Sheriff’s Office, and its numbers cover the whole area it patrols, not just Diablo.
Crimes reported in the parts of Contra Costa County it patrols: the towns and villages without police of their own.
Property crimes (burglary, theft, stolen cars)
Violent crimes (assault, robbery, rape, murder)
These are counts, not rates. The FBI doesn’t publish how many people each agency covers, so we can’t turn them into a per-resident figure or a Safety Grade. Source: FBI Uniform Crime Reporting, offenses known to law enforcement by county and by state agency.
