Since 1930, the Federal Bureau of Investigation’s (FBI) Uniform Crime Reporting (UCR) program has collected data on crimes reported to law enforcement agencies throughout the United States. Recently, the FBI released data on crime in 2016. These data likely underestimate the total number of crimes that have actually occurred. This is because they do not include unreported crime, and some reported crimes—including all drug crime—are excluded. Despite these limitations, the UCR data provide useful metrics for tracking changes in crime rates over time. In this report, we present crime trends in California and show how California compares to nationwide trends.
