Grimes is covered by the county

Grimes has no police department of its own in the FBI’s data. Calls here most likely go to the Polk County Sheriff’s Office, and its numbers cover the whole area it patrols, not just Grimes.

Polk County Sheriff’s Office

Crimes reported in the parts of Polk County it patrols: the towns and villages without police of their own.

Property crimes (burglary, theft, stolen cars)

Violent crimes (assault, robbery, rape, murder)

▼ Property crime down 33% since 2022→ Violent crime about the same since 2022

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.

The Safety Grade is our own summary of that data, not an official rating. Natural hazards: FEMA National Risk Index and flood insurance claims. Hospitals: CMS Hospital General Information. This isn’t an official statement of public safety. In an emergency, call 911.
