The FBI’s Uniform Crime Reporting (UCR) Program counts one arrest for each separate instance in which a person is arrested, cited, or summoned for an offense. The UCR Program collects arrest data on 29 offenses, as described in Offense Definitions. Because a person may be arrested multiple times during a year, the UCR arrest figures do not reflect the number of individuals who have been arrested. Rather, the arrest data show the number of times that persons are arrested, as reported by law enforcement agencies to the UCR Program.
The UCR Program considers a juvenile to be an individual under 18 years of age regardless of state definition. The program does not collect data regarding police contact with a juvenile who has not committed an offense, nor does it collect data on situations in which police take a juvenile into custody for his or her protection, e.g., neglect cases.
Expanded data about arrests include information about the age, gender, and race of the arrestees. These data are available in the following tables:
