Rate:  Number of Crimes per 100,000 Inhabitants, Additional Information About Selected Offenses by Population Group, 2011

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

General comments

  • This table provides the rate per 100,000 inhabitants and breakdowns (such as attempts, weapons, type of entry, and property types for the offenses of forcible rape, robbery, aggravated assault, burglary, and motor vehicle theft) nationally and by city and county groupings for law enforcement agencies submitting 12 months of complete data for 2011.  In addition, the table furnishes the number of agencies meeting the criteria for inclusion in this table and provides the estimated population for each population group. 
  • The totals provided in this table reflect only those offenses for which law enforcement agencies provided additional information to the UCR Program; therefore, the totals will not match those shown in other rate tables.  
  • The FBI publishes only data that conform to UCR data collection guidelines.  For example, the data collection methodology for the offense of forcible rape used by the state UCR Programs administered by the Minnesota Department of Public Safety do not comply with these guidelines, therefore, those data are not available for inclusion in this table.  Instead, the FBI computes the rates by estimating forcible rape offenses for each population group for participating agencies Minnesota.  The figures are estimated using the national rates for each population group applied to the population by group for Minnesota agencies supplying 12 months of complete data. 
  • 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.
  • The UCR Program does not include murder or arson offenses in this table.  Information about these offenses can be found in the respective sections of this report:  Expanded Homicide Data and Arson.

Methodology

  • The data used in creating this table were from all law enforcement agencies submitting 12 months of complete data (except arson) for 2011.
  • The FBI derived the offense rates by first dividing the aggregated offense counts by the aggregated populations covered by contributing agencies for which 12 months of complete data were supplied and then multiplying the resulting figure by 100,000.

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.
