Crime in the United States
by Region, Geographic Division, and State, 2005-2006
The FBI collects these data through the Uniform Crime Reporting (UCR) Program.
- This table provides the estimated number and rate (per 100,000 inhabitants) of crime in each region, geographic division, and state in 2006 and 2005, and the percent change in each.
- The UCR Program does not have sufficient data to estimate arson offenses.
- For Illinois, valid counts for murder, forcible rape, robbery, and aggravated assault were available only for agencies in cities 100,000 and over in population. For other agencies, the only available data generated by the Illinois State Program were totals based upon an incident-level system without indication of multiple offenses recorded within single incidents. Therefore, the UCR Hierarchy Rule could not be applied in order to convert the state’s data to Summary format. (The Hierarchy Rule requires that only the most serious offense in a multiple-offense criminal incident is counted.) To arrive at a comparable state estimate to be included in national compilations, the Illinois State Program’s totals were reduced by the proportion of multiple offenses reported within single incidents in the National Incident-Based Reporting System database. Data for cities 100,000 and over in population were excluded from the reduction process.
- The data collection methodology for the offense of forcible rape used by Illinois (with the exception of Rockford, Illinois) and Minnesota (2006 data) do not comply with national UCR Program guidelines. Consequently, their figures for forcible rape were estimated for inclusion in this table.
Caution against ranking
Any comparisons of crime among different locales should take into consideration relevant factors in addition to the areas’ crime statistics. Variables Affecting Crime
provides more details concerning the proper use of UCR statistics.
- The data used in creating this table were from all law enforcement agencies in the UCR Program (including those submitting less than 12 months of data).
- Crime statistics include estimated offense totals (except arson) for agencies submitting less than 12 months of offense reports for each year.
- The FBI derives state totals by estimating for nonreporting and partially reporting agencies within each state. Using the state’s individual agency estimates, the Program aggregates a state total.
- State totals for 2005 have been reestimated to reflect data received after the publication of the 2005 edition of Crime in the United States.
The FBI calculated 2006 state growth rates using revised 2005 state/national population estimates and 2006 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 2006 state growth rate to the updated 2005 U.S. Census Bureau data.
