What this data can and can’t tell you
- It’s reported crime. Only incidents reported to and recorded by police appear here. Many thefts and some assaults are never reported.
- Small numbers swing. In a town of about 6,100, a handful of incidents moves the rate noticeably from year to year. The trend matters more than any one year.
- Visitors count too. Towns with a campus, highway, beach or shopping center see incidents involving people who don’t live there.
- Gaps are real gaps. A missing year means the department didn’t report a full year, not that nothing happened.
