Ferney is policed by the county: what that means
Ferney has no police department of its own: it’s an unincorporated community (a census-designated place) in Brown County. The Brown County Sheriff’s Office reports to the FBI for the parts of the county without police of their own, so there are no figures for Ferney alone, and no Safety Grade. Aberdeen, 20 miles away, is the nearest town with a Safety Grade (C).

What this data can and can’t tell you
- It’s reported crime. Only incidents reported to and recorded by police appear here. Many crimes are never reported to police.
- A county agency covers a wide area. Its totals mix many communities, so they say little about any one of them.
- Gaps are real gaps. A missing year means the department didn’t report a full year, not that nothing happened.
