Summary This article explains how the Recorded Repeats Adjustment Calculator (RRAC) tool can be used to give a truer estimate of the rate of repeat victimization than can be obtained from police data. The study analysed patterns in break and enter crimes recorded by police during a five year period in Vancouver. A significant finding was that 20% of recorded burglaries were repeat burglaries but the adjusted figure, using the measurement tool, showed they were nearly half of all burglaries. Similarly, using the RRAC tool the authors showed that households with five or more burglaries had an adjusted rate 20 times higher than was found in the police records. The authors suggest that this tool can be used by researchers for other crime types and can overcome the major under-recording of repeat victimisation in police data.
