The FBI collects these data through the Uniform Crime Reporting (UCR) Program.
The data used in creating this table were from all metropolitan county law enforcement agencies submitting 12 months of arrest data for both 2005 and 2006.
The FBI calculated 2006 state growth rates using revised 2005 state/national population estimates and 2006 provisional state/national population estimates provided by the U.S. Census Bureau. The FBI then estimated population figures for counties by applying the 2006 state growth rate to the updated 2005 U.S. Census Bureau data. Similarly, the FBI estimated 2005 population figures for counties by applying the 2005 state growth rates to the updated 2004 U.S. Census Bureau data. The 2005 state growth rate was based on the difference between the U.S. Census Bureau’s 2004 revised population estimates and 2005 provisional population estimates.
