Arrest Trends, Cities, by Sex, 2009–2010
The FBI collects these data through the Uniform Crime Reporting (UCR) Program.

General comments

  • This 2-year trend table provides the number of males and females arrested in cities in 2009 and 2010 and the percent change when the data for these 2 years are compared. The table furnishes a breakdown of these data by gender for juveniles (persons under age 18). 
  • 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 2009 and 2010.

Population estimation

For the 2010 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 2009 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 2009 Census population estimate to derive the agency’s 2010 population estimate. 

Population estimates for 2009 are based on the percent change in the state population from the U.S. Census Bureau’s 2008 revised estimates and 2009 provisional estimates.
