The International Classification of Crime for Statistical Purposes (ICCS) - Arabic, Chinese, English, French, Russian, Spanish - is a classification structure of criminal offences. On the basis of internationally agreed concepts and principles, the ICCS consists of a framework to assign criminal offences to hierarchical categories that have a certain degree of similarity in relation to conceptual, analytical and policy areas. The purpose of the ICCS is to enhance consistency and international comparability of crime statistics and improve analytical capabilities at both the national and international levels.

The United Nations Statistical Commission, at its 46th session in March 2015, and the Commission on Crime Prevention and Criminal Justice at its 24th session in May 2015 have endorsed the ICCS as an international statistical standard for data collection, both from administrative records and survey generated data, and as an analytical tool to elicit unique information on crime drivers and factors. The two Commissions have also confirmed UNODC as the custodian of the ICCS and have confirmed the draft implementation plan for the classification at national, regional and international levels, including the creation of a technical advisory group to provide substantive advice to the maintenance of the ICCS.
