Deviant and criminal behavior is the result of the mutual personal characteristics of the perpetrator of the criminal offence and the characteristics of the environment in which he is located. There are various factors that influence shaping such behavior in juveniles including family, school and dropping out of regular education, peer pressure, media and video games. Prevention programs are important to reduce or prevent juvenile delinquency. In most European countries, including Croatia, there is an increase in the use of alternative sanctions and informal forms of treatment in practice towards juvenile offenders. This paper deals with juvenile delinquency in Croatia. The reported criminal offenses of juveniles aged 14 to 18 during 2011, 2013, 2015, 2017 and 2019 were analyzed.
