This study compares the data from Federal Bureau of Investigation Summary Uniform Crime Reports and National Incident-Based Reporting System (NIBRS) for 1,131 agencies. |
|
Abstract:
|
Using data from 1991 to 1996, this study identifies which Index crime rates are most affected by NIBRS reporting and examines the extent to which rates change. The following underlying causes for these differences are investigated: structural differences, non-uniform reporting practices, reporting errors, and software coding errors. When comparing data from the same year for the jurisdictions in this study, NIBRS rates differ only slightly from Summary UCR. Murder rates are the same. Rape, robbery, and aggravated assault rates in NIBRS are about 1 percent higher, on average, than in Summary UCR. NIBRS burglary rates are lower by an average 0.5 percent. NIBRS larceny rates are higher by an average 3.4 percent. NIBRS motor vehicle theft rates are higher by an average 4.5 percent. |
