¹ Limited data for 2006 were available for Illinois.
² The data collection methodology for the offense of forcible rape used by the Illinois (with the exception of Rockford, Illinois) and the Minnesota state UCR Programs does not comply with national UCR Program guidelines. Consequently, their figures for forcible rape and violent crime (of which forcible rape is a part) are not published in this table.
³ The FBI does not publish arson data unless it receives data from either the agency or the state for all 12 months of the calendar year.
⁴ Because of changes in the state/local agency's reporting practices, figures are not comparable to previous years' data.
