This report presents conclusions from research on prostitution-related crimes and the crime of trafficking in children for commercial sexual exploitation. English translation is the summary of the full version of the report available in Polish. The goal of the study was to reveal the course and characteristics of the phenomenon of exploiting children in prostitution. To achieve this goal, the researchers conducted a sociological analysis of events meeting the statutory criteria of prostitution-related crimes or the crime of human trafficking where the victims were underage, focusing both on the victim and on the perpetrator, as well as a legal analysis of the actions performed by law enforcement and criminal justice authorities. Since criminal justice authorities do not keep a record of all cases involving underage victims, it was impossible to randomly select a representative sample of cases. At the same time, temporal and financial constraints made it impossible to review the records of all the courts that granted their permission. Therefore, the presented study should be regarded as non-representative. Nevertheless, it may become an important step toward understanding the reality and specific features of prostitution-related crimes against children.
