The FBI collects these data through the Uniform Crime Reporting (UCR) Program.
The data used in creating this table were from all law enforcement agencies submitting 12 months of arrest data for both 1997 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 the Nation by applying the 2006 state growth rate to the updated 2005 U.S. Census Bureau data. Similarly, the FBI estimated 1997 population figures for the Nation by applying the 1997 state growth rates to the updated 1996 U.S. Census Bureau data. The 1997 state growth rate was based on the difference between the U.S. Census Bureau’s 1996 revised population estimates and 1997 provisional population estimates.
