Table 15 Data Declaration
Crime Trends, Additional Information About Selected Offenses by Population Group, 2010-2011
The FBI collects these data through the Uniform Crime Reporting (UCR) Program.
General comments
- This 2-year trend table provides the 2010 and 2011 breakdowns (such as attempts, weapons, type of entry, and property types for the offenses of forcible rape, robbery, aggravated assault, burglary, motor vehicle theft, and arson) and the percent change between these 2 years.
- Suburban areas include law enforcement agencies in cities with less than 50,000 inhabitants and county law enforcement agencies that are within a Metropolitan Statistical Area.
- Suburban areas exclude all metropolitan agencies associated with a principal city. The agencies associated with suburban areas also appear in other groups within this table.
Methodology
- The data used in creating this table were from all law enforcement agencies submitting at least 6 common months of complete offense reports with breakdowns for 2010 and 2011.
- A crime trend represents the percentage change in crime based on data reported in a prior equivalent period. In calculating trends, the UCR Program includes only common reported months for individual agencies.

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.
