United Nations Surveys on Crime Trends and the Operations of Criminal Justice Systems 1970-2006

The CTS questionnaires are sent to Member states on an annual basis to collect incidence of victimization reported to the authories within the country. CTS results are disseminated through UNODC crime and criminal justice statistics and covers a variety of topics including statistics on crime, drug use, criminal justice, and drug trafficking and prices.

Data are subject to accuracy problems of all official crime data as errors occur both along both the victim and police reporting process.

Data from the CTS can be obtained from the UNODC website.
