Source and notes
FBI Crime Data Explorer, Uniform Crime Reporting Program (Public domain (U.S. government work); source FBI Uniform Crime Reporting Program).
These are the crimes the Thornton police reported to the FBI's Uniform Crime Reporting program, per 100,000 people the department serves. Violent crime is murder, rape, robbery and aggravated assault; murder includes nonnegligent manslaughter. Property crime is burglary, theft and car theft. A year counts only when the department reported violent crimes in all 12 months, and not when its rate is far out of line with the years either side (under a quarter, or over 1.75 times, of both), which means it sent only part of its reports or some twice. In 2021 the FBI took only reports from its newer system (NIBRS), and many departments hadn't switched yet, so that year is often missing or less certain. NIBRS counts every crime in an incident, not just the most serious, so a jump or drop when a department switched can come from the change in counting rather than in crime. The FBI widened its definition of rape in 2013. A city's rate depends on where its borders fall, so compare cities with care. The U.S. rates count only the agencies that reported, so they differ a little from the FBI's national estimates.
