Table 62 Data Declaration
Arrest Trends, Suburban Areas, 2017–2018
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 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 2-year trend table provides the reported number of persons arrested in suburban areas in 2017 and 2018 and the percent change 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.
- Suburban area law enforcement agencies are defined as all agencies within a currently designated Metropolitan Statistical Area, excluding those agencies that cover principal cities as defined by the U.S. Office of Management and Budget.(See Area Definitions.)
- 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 suburban area law enforcement agencies submitting 12 months of arrest data for both 2017 and 2018.
- The rape figures in this table are aggregate totals of data submitted using both the legacy and revised UCR definitions of rape.
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.
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.
