Crime Trends, Additional Information About Selected Offenses by Population Group, 2009-2010

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

General comments

  • This 2-year trend table provides the 2009 and 2010 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 2009 and 2010. 
  • 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 groups

The UCR Program uses the following population group designations:

Population GroupPolitical LabelPopulation Range

II City 100,000 to 249,999
III City 50,000 to 99,999

IX (Metropolitan County)2 County N/A

1Includes universities and colleges to which no population is attributed.

Population estimation

For the 2010 population estimates used in this table, the FBI computed individual rates of growth from one year to the next for every city/town and county using 2000 decennial population counts and 2001 through 2009 population estimates from the U.S. Census Bureau. Each agency’s rates of growth were averaged; that average was then applied and added to its 2009 Census population estimate to derive the agency’s 2010 population estimate.
