Percent Change for Consecutive Years, January-June 2012

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

General comment

This table provides the percent change in offenses known to law enforcement for the
nation for the first 6 months in consecutive years from 2008 through 2012.

Methodology

The data used in creating this table were from law enforcement agencies submitting 3 to
6 common months of offense reports from 2008 through 2012. 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 the 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.
