Uniform crime reporting (UCR) is a collective effort on the part of city, county and state law enforcement agencies to present a nationwide view of crime. The California Department of Justice (DOJ) UCR program provides a statewide view of crime, based on the reporting of statistics.

*Effective January 1, 2014, the California Department of Justice revised the definition of rape. Thus, some crime reports with a sexually based offense will now be reported as a Part I crime (rape). Examples include: PC288-Sexual Abuse, PC243.4 Sexual Battery, PC289-Sexual penetration, and PC286-Sodomy. 

Above you will find the number of Part 1 Crimes reported by the Orange County Sheriff's Department. They are categorized by crime type. Statistics are preliminary and subject to further analysis and revision.

The YTD statistics are reported from January to present month. The YTD % Change column compares statistics between 2014 YTD and 2015 YTD indicating an increase or decrease in the crime type.

The FBI does not publish arson data unless it receives data from the agency for all 12 months of the calendar year. Arson is defined as any willful or malicious burning or attempting to burn.
