Criminological and criminal justice research is a relatively new academic discipline in Cyprus. The current paper first examines and critiques official data on juvenile delinquency in Cyprus. As expected, the findings on delinquency and victimization gathered from self-reported surveys suggest higher rates of delinquency than those based on official statistics. This paper is based for a large part on data obtained from the International Self-reported Delinquency Study (ISRD-2), a national survey of 2385 Cypriot 12–16 year old pupils concerning a number of delinquency risk and protective factors. Those results were compared to the data collected as part of the ISRD-2 in five European Union (EU) member states, which – like Cyprus - joined the EU in 2004. This comparison focuses on data in the capitals of the six countries concerned. Research and delinquency prevention implications are discussed.
