Crime comparisons between countries can be made via surveys designed to assess experience with actual criminal victimisation. Crime statistics are based on the 2005 International Crime Victim Survey (ICVS). The ICVS focuses on ten types of "conventional" crimes. Respondents are asked about victimisation by these conventional crimes that they themselves or their households experienced. These crimes cover vehicle-related crimes, burglary, theft of personal property, and contact crimes.
