Topical Analysis Examples Using NIBRS
Juvenile Multiple Offender Analysis
Are juveniles aged 10 - 17 more likely than adults to be involved in multiple offender incidents?
What types of offenses are reported in juvenile multiple offender incidents and adult multiple offender incidents?
At what time of day are most juvenile multiple offender property offenses committed?
What offenses are reported in juvenile multiple offender incidents in which the most serious offense is a Part I Index property crime?
Elderly Victimization Analysis
For which violent crimes perpetrated in residential settings are adults aged 65 or older more likely than people aged 64 or younger to be victimized?
For violent person crimes, when is the victimization of a person aged 65 or older in a residential setting most likely to occur?
Does the offender age differ by victim-offender relationship for older adult and younger victims of robbery?
Intimate Partner Violence Analysis
Is there a difference between gender and age groups in the types of injuries sustained by victims in violent intimate partner incidents?
What violent offenses did intimate partners commit and where were the offenses committed?
Is there a difference in weapon use against female vs. male victims of intimate partner violence?
