Table 32 Data Declaration
Ten-Year Arrest Trends, Totals, 2008–2017
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 10-year trend table provides the number of persons arrested in 2008 and 2017 and the percent change (except for rape) when the data for these 2 years are compared. The table furnishes a breakdown of these data by juveniles (persons under age 18) and adults.
- 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 submitting 12 months of arrest data for both 2008 and 2017.
- The 2008 rape figures are based on the legacy definition and the 2017 rape figures are aggregate totals based on both the legacy and revised definitions. For this reason, a percent change is not provided.
For the 2017 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 2016 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 2016 Census population estimate to derive the agency’s 2017 population estimate.
For the 2008 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 2000 decennial population counts and 2001 through 2007 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 2007 Census population estimate to derive the agency’s 2008 population estimate.
