Résumé
The purpose of this research was to examine whether spatial concentrations of crime exist in two types of crime: robbery and spousal assault. The present research explored spatial patterns of spousal assault and robbery by mapping out the Vancouver Police Department's data of calls for service in selected years between 1989 and 2000 utilizing Geographic Information Systems (GIS). It was found that in both crimes, spatial patterns exist and these patterns were stable during the observed time periods. By examining repeat victimization of locations, it was supported that repeatedly victimized locations disproportionately contribute to both spatial crime patterns and crime rates. As a last step, Location Quotients of Crime (LQC) were calculated for both crimes to assess the relative risks and centres of both crimes.
