Table 12, Data Declaration
Crime Trends by Population Group, 2004-2005
Download Data Declaration
The FBI collects these data through the Uniform Crime Reporting (UCR) Program.
- This two-year trend table provides the number of offenses for 2004 and 2005, and the percent change between these two years, listed by population group.
- The Suburban and Nonsuburban Cities classification encompasses all cities other than principal cities served by municipal law enforcement agencies within Metropolitan Statistical Areas.
- 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 trends for this table. Instead, the FBI computes the trends 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.
- The data used in creating this table were from all law enforcement agencies submitting at least 6 common months of complete offense reports for 2004 and 2005.
- In calculating trends, the UCR Program includes only common reported months for individual agencies.
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.
