The paper investigates the issue of reporting and the willingness to report corruption in relation to the willingness to report other forms of victimisation among students in South Eastern European countries. The aim of the paper is to provide answers to the questions of how willing students are to report corruption and to what extent their willingness is related to the willingness to report other forms of victimisation, as well as to their socio-demographic characteristics, such as sex, country of residence and field of study. Based on the results obtained, the purpose of the paper is, firstly, to identify opportunities for encouraging young people to report corruption, as well as other types of crime, and secondly, to identify to which groups in terms of their sociodemographic characteristics additional attention should be devoted when encouraging them to report. The focus is on young people since the possibility to influence willingness to report is believed to decrease with age. The research was conducted on a convenience sample of 1400 students from Bosnia and Herzegovina, Montenegro, Croatia, Hungary, Macedonia, Slovenia and Serbia (200 per country) by using the survey quantitative method. The research instrument was a questionnaire in which the respondents were asked about their socio-demographic characteristics, as well as 10 vignette questions containing short descriptions of various types of crime, i.e., 5 hypothetical situations in which they are victims of crime and 5 hypothetical situations in which they are witnesses of crime. Based on the hypothetical situations, the respondents were asked to assess whether they would report crime on a scale from 1 (I am absolutely certain that I would report) to 4 (I am absolutely certain that I would not report). The results of the descriptive and multivariate analysis show statistically significant differences in willingness to report various types of crime among young people in the South Eastern European countries examined.
