How much crime is reported in Olathe?
In 2024, law enforcement reported 293 violent and 1,407 property offenses in the Olathe jurisdiction — a violent-crime rate of 196.0 per 100,000, below the U.S. estimate of 359.1.
Reported offenses known to law enforcement from the FBI Uniform Crime Reporting Program (CIUS Table 8), 2024.
