In criminology, delinquency and criminality are described as primarily male activities ; this is the conclusion of many studies. Moreover, most of the researches that have studied delinquent phenomenon are based on samples of boys or men. Consequently, few data are available on girls’ delinquency. Our study draws up an inventory of delinquent activity in a sample of 241 minors, 168 boys and 73 girls, living in Gap and Grenoble and their suburbs.
