Where and when? Examining spatiotemporal aspects of sexual assault events

This research investigates the where and when of sexual assaults to determine what types of sexual crimes are committed at different time and place classifications. Exhaustive CHAID (chi-squared automatic interaction detection) analyses are conducted, examining factors associated with crimes that were committed indoors or outdoors, in private or public places, during the day or at night, and during the week or on the weekend. These methods are applied to a sample of 361 sexual crime events committed by 72 serial sex offenders. The results are strikingly different dependent on which spatial or temporal aspect of the crime is examined, which implies the complexity of sexual crime events and their situational components. This research brings to light possible policy implications with respect to situational crime prevention.
