About ISRD

This page provides a short overview of the International Self-Report Delinquency Study (ISRD). For further detail, please consult the main menu on top, which enables you to navigate to country-specific pages and other information.

At a glance

  • ISRD1: 13 countries (1992-1993)
  • ISRD2: 31 countries (2005-2007)
  • ISRD3: 34 countries (2012-2019)


  • The ISRD project is an international collaborative study, which repeatedly (ISRD1, ISRD2 and now ISRD3) collects data on juvenile delinquency and victimization from comparable (but not identical) samples.

Major objectives

  • To observe and compare differences, similarities and trends in offending and victimization between countries. The primary focus is on Europe, but the sample also includes a number of non-European countries.
  • To explore and test theoretical issues related to juvenile delinquency, maintaining relevance for policy purposes.


  • ISRD uses a standardized self-report survey (with the possibility of national modules for ISRD3) conducted in school settings among students in grades 7,8 and 9 (or equivalent grades for children age 12-16), randomly selected from schools in two medium or large cities.


  • Primarily a city-based survey, but some national surveys with oversampling of two cities for comparability.
  • A minimum of two cities in each country.
