Table 44 Data Declaration
Arrest Trends, Cities, 2013–2014
The FBI collects these data through the Uniform Crime Reporting (UCR) Program.
Important note about rape data
In 2013, the FBI UCR Program initiated the collection of rape data under a revised definition and removed the term “forcible” from the offense name. The UCR Program now defines rape as follows:
Rape (revised definition): 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. (This includes the offenses of rape, sodomy, and sexual assault with an object as converted from data submitted via the National Incident-Based Reporting System.)
Rape (legacy definition): The carnal knowledge of a female forcibly and against her will.
The rape figures in this table are aggregate totals of the data submitted based on both the legacy and revised UCR definitions.
General comments
- This 2-year trend table provides the number of persons arrested in cities in 2013 and 2014 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.
- City law enforcement agencies are defined as all agencies within Population Groups I–VI. (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.
Methodology
The data used in creating this table were from all city law enforcement agencies submitting 12 months of arrest data for both 2013 and 2014.
Population estimation
For the 2014 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 2013 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 2013 Census population estimate to derive the agency’s 2014 population estimate.
For the 2013 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 2012 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 2012 Census population estimate to derive the agency’s 2013 population estimate.
