Percent Change, by Population Group

The FBI collects these data through the Uniform Crime Reporting Program.

General comment

This table provides the percent change in offenses known to law enforcement, by population group, for 2010 and 2011.


The data used in creating this table were from law enforcement agencies submitting 6 or more common months of offense reports for 2010 and 2011. When the FBI determines certain variables have created unusual fluctuations in the data, those data are excluded from the trend tabulations.

Population estimation

The FBI calculated 2011 state growth rates using the U.S. Census Bureau’s 2010 decennial state/national population figures and 2011 provisional state/national population estimates. The FBI then estimated population figures for city jurisdictions by applying the 2011 state growth rate to the 2010 U.S. Census Bureau data.
