United Nations Surveys of Crime Trends and Operations of Criminal Justice Systems
Collects data on the incidence of reported crime and the operations of criminal justice systems with a view to improving the analysis and dissemination of that information globally. Results provide an overview of trends and interrelationships between various parts of the criminal justice system to promote informed decision-making in administration, nationally and internationally. The surveys were started in 1977, covering 5-year intervals from 1970-1994. Starting in 1995 surveys cover 2 or 3 year intervals. Data may also be accessed through ICPSR.
