Data are from the California Department of Justice, Office of the Attorney General, Interactive Crime Statistics. Data for Silicon Valley includes San Mateo and Santa Clara Counties. Population data is from the California Department of Finance, Mid-Year Annual Intercensal Population Estimates by Race/Ethnicity with Age and Gender Detail and Population Projections by Age. Juveniles include children ages 10-17, and adults include the at-risk population (ages 18-69). Felony offenses include Violent, Property Offenses, Drug Offenses, Sex Offenses, Weapons, Driving Under the Influence, Hit and Run, Escape, Bookmaking, Manslaughter Vehicular, and Other Felonies. In November 2014, California voters passed Proposition 47 which reduced numerous state statutes from felonies to misdemeanors. Caution should be used when comparing felony and misdemeanor arrest data to prior years. Additionally, in November 2016, California voters passed Proposition 64 which legalized the possession and use of marijuana for individuals 21 years of age and older and reduced the offense degree for numerous state statutes. Caution should be used when comparing drug offense arrests to prior years. Starting in 2021, the California Department of Justice arrest numbers started including transgender individuals in the male and female gender categories; however, arrest numbers for the non-binary gender category are not included in the data due to the small population size.

*The felony arrest rates for 2015 and subsequent years were affected by the passage of Propositions 47 (2014) and 64 (2016), so caution is advised in comparing to previous years.

California Department of Justice felony arrest data do not include the gender non-binary category due to the small sample size.
