Crime statistics are compiled from UCR data and published annually by the FBI in the Crime in the United States series. The FBI does not collect the data itself. Rather, law enforcement agencies across the United States provide the data to the FBI, which then compiles the Reports.

What does the UCR rely on?

The UCR relies on official data that have been collected and reported by law enforcement agencies. The NCVS and other surveys discussed in this report are large-scale social surveys that rely on self-reports of offenses or victimization.

Who is the UCR compiled by?

Each year, the Federal Bureau of Investigation (FBI) publishes the Uniform Crime Reports which consists, in part, of a detailed analysis of eight major crime categories covering jurisdictions of various sizes in the United States. The UCR Program collects statistics on the number of offenses known to law enforcement.
