How much crime is reported in San Diego?
In 2024, law enforcement reported 5,726 violent and 23,197 property offenses in the San Diego jurisdiction — a violent-crime rate of 412.2 per 100,000, above the U.S. estimate of 359.1.
Reported offenses known to law enforcement from the FBI Uniform Crime Reporting Program (CIUS Table 8), 2024. Figures describe the FBI agency jurisdiction: San Diego — an FBI jurisdiction population of 1,389,024, versus the Census place population of 1,406,106. The rate per 100,000 is the FBI's own (count ÷ that jurisdiction population), never divided by the Census place figure. These are reported crimes under voluntary participation — not measured or victimization crime — and the FBI cautions against using them to rank or compare places. See methodology §31.
