This paper uses the location quotient, a common measurement from economic geography and regional economics, to capture the specialization of criminal activity in Vancouver, Canada. Location quotients have barely been introduced into criminological research, yet they provide additional insight into crime analysis not available using crime counts and crime rates. The location quotients for automotive theft, break and enter, and violent crimes are mapped for Vancouver, Canada, and tested using social disorganization and routine activity theory as a theoretical framework. Strong support is found for these theories to predict specialization in criminal activity by interpreting their expectations in the context of crime-specific attractors.
