Neighboring departments count the same offenses the same way, but their areas, populations and visitors differ, so a difference between two towns is a starting point for a question, not an answer.

How to read these numbers

These are offenses known to the police and reported to the FBI’s Uniform Crime Reporting Program: crimes nobody reported, or that a department did not record, are not in them.

Violent crime is murder and nonnegligent manslaughter, rape, robbery and aggravated assault; property crime is burglary, larceny-theft, motor vehicle theft and arson.

A department reports the crimes in the area it polices, which can differ from the town’s boundaries, and the FBI estimates the population it serves.

The FBI asks that these figures not be used to rank places or to judge how safe a neighborhood is: crime depends on many local factors, and the counts describe a whole town, not any street or home.

A year is shown only when the department reported all twelve months.
