The Costs of Crime: Who Pays and How Much? is a revision of The Crime Bill: Who Pays and How Much? (Brantingham and Easton 1996) that expands and brings up to date the statistics presented in the original publication. The purpose of this primer is to describe (1) what kinds of crime Canadians are exposed to, (2) who is at risk from these crimes, (3) who commits what crimes, (4) what costs the victims face, and (5) what expenditures we make to prevent crime. To understand what changes we may want to make in our criminal justice system, it is important to see the overall patterns of crime and punishment, how they have evolved, and what they have cost.
