Table 16, Data Declaration
Rate: Number of Crimes per 100,000 Inhabitants, by Population Group, 2005
Download Data Declaration
The FBI collects these data through the Uniform Crime Reporting (UCR) Program.
- This table provides the rate per 100,000 inhabitants and the number of offenses known for violent crime (murder and nonnegligent manslaughter, forcible rape, robbery, and aggravated assault) and property crime (burglary, larceny-theft, and motor vehicle theft) nationally and by city and county groupings. In addition, the table furnishes the number of agencies that provided data to the UCR Program as well as the estimated population for each population group.
- The UCR Program does not have sufficient data for publishing arson offenses in this table; therefore, arson figures are not included.
- The FBI publishes only data that conform to UCR data collection guidelines. The data collection methodology for the offense of forcible rape used by the state UCR Program administered by the Illinois State Police does not comply with these guidelines, so the FBI does not use these data in computing the rates for this table. Instead, the FBI computes the rates by estimating for forcible rape for Illinois by applying the national rates for each population group to the population by group for Illinois agencies supplying 12 months of complete data.
- Nonmetropolitan counties include state police agencies that report aggregately for the entire state.
- The Suburban and Nonsuburban Cities classifications in this table encompass all cities other than principal cities served by municipal law enforcement agencies in Metropolitan Statistical Areas (MSAs).
- The data used in creating this table were from all law enforcement agencies submitting 12 months of complete data (except arson) for 2005.
- The FBI derived the offense rates by first dividing the total aggregated offense estimates by the aggregated populations covered by contributing agencies and then multiplying the resulting figure by 100,000.
The UCR Program uses the following population group designations:
||250,000 and more
||100,000 to 249,999
||50,000 to 99,999
||25,000 to 49,999
||10,000 to 24,999
||Less than 10,000
|VIII (Nonmetropolitan County)
|IX (Metropolitan County)
1Includes universities and colleges to which no population is attributed.
2Includes state police to which no population is attributed.
The FBI calculated 2005 state growth rates using revised 2004 state/national population estimates and 2005 provisional state/national population estimates provided by the U.S. Census Bureau. The FBI then estimated population figures for city and county jurisdictions by applying the 2005 state growth rate to the updated 2004 U.S. Census Bureau data.
