Crime in the United States
by Region, Geographic Division, and State, 2006-2007
The FBI collects these data through the Uniform Crime Reporting (UCR)
- This table provides estimated number and rate (per 100,000 inhabitants)
of crime in each region, geographic division, and state in 2006 and 2007,
and the percent change in each.
- For Illinois, valid counts for murder, robbery, aggravated assault,
burglary, larceny-theft, and motor vehicle theft 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
(with the exception of Minneapolis and St. Paul, Minnesota) do not comply
with national UCR Program guidelines. Consequently, their figures for
forcible rape were estimated for inclusion in this table.
- The UCR Program does not have sufficient data to estimate for arson.
Caution against ranking
Any comparisons of crime among different locales should take into consideration
relevant factors in addition to the area’s crime statistics. Variables

- 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 2006 were reestimated if necessary to reflect data
received after the publication of the 2006 edition of Crime in the
For the 2007 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 2006
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 2006
Census population estimate to derive the agency’s 2007 population estimate.
