Cities, by Age, 2009
The FBI collects these data through the Uniform Crime Reporting (UCR) Program.
- This table provides the number of persons arrested in cities in 2009. These data are broken down by the age of the arrestee and include the percent distribution of arrests by offense type.
- The number of persons arrested, broken down by age of the arrestee, reported by city law enforcement agencies is used to derive the national figures presented in Table 38.
- City law enforcement agencies are defined as all agencies within Population Groups I–VI. (See Area Definitions.)
- The UCR Program collects arrest data for 29 offenses.
- 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 city law enforcement agencies submitting 12 months of arrest data for 2009.
For the 2009 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 2008 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 2008 Census population estimate to derive the agency’s 2009 population estimate.
