The county’s figures, for the wider area
Naperville’s own police figures aren’t in the FBI’s data. These are the numbers the DuPage County Sheriff’s Office reports for the parts of DuPage County it patrols, which usually don’t include a town with its own police.
Crimes reported in the parts of DuPage 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.
