Table 69 Data Declaration
Arrests, by State, 2018
The FBI collects these data through the Uniform Crime Reporting (UCR) Program.
Important note about rape data
In 2013, the FBI’s UCR Program initiated the collection of rape data under a revised definition within the Summary Based Reporting System. The term “forcible” was removed from the offense name, and the definition was changed to “penetration, no matter how slight, of the vagina or anus with any body part or object, or oral penetration by a sex organ of another person, without the consent of the victim.”
In 2016, the FBI Director approved the recommendation to discontinue the reporting of rape data using the UCR legacy definition beginning in 2017.
- This table provides arrest data reported for each state for 2018. The table provides both total arrests and arrests of juveniles (persons under the age of 18).
- These data represent the number of persons arrested; however, some persons may be arrested more than once during a year. Therefore, the statistics in this table could, in some cases, represent multiple arrests of the same person.
- The data used in creating this table were from all law enforcement agencies that submitted 12 months of arrest data for 2018.
- The rape figures in this table are aggregate totals of data submitted using both the legacy and revised UCR definitions of rape.
- Arrest totals are aggregates of the totals reported by agencies providing data to the UCR Program within each state.
- Any comparison of statistics in this table should take into consideration variances in arrest practices, particularly for Part II crimes. (Offense Definitions define the UCR Program’s Part II offenses.)
Arrest information for 2018
- No 2018 arrest data were received from the District of Columbia’s Metropolitan Police Department. The two agencies in the District of Columbia for which 12 months of arrest data were received, the District of Columbia Fire and Emergency Medical Services: Arson Investigation Unit, and the Metro Transit Police, have no attributable population.
- For 2018, only arrest totals (with no age or gender breakdowns) are available for Florida. Therefore, Florida arrest totals are included only in this table.
- Limited arrest data were received from the Illinois state UCR Program. (Arrest counts presented in this table are for Chicago and Rockford only.)
- No 2018 arrest data were received from the New York City Police Department.
For the 2018 population estimates used in this table, the FBI computed individual rates of growth from one year to the next for every city/town and county using 2010 decennial population counts and 2011 through 2017 population estimates from the U.S. Census Bureau. Each agency’s rates of growth were averaged; that average was then applied and added to its 2017 Census population estimate to derive the agency’s 2018 population estimate.
