In this article, I discuss the functions and effects of ADOS, a voluntary association, on second generation immigrants in Goutte-d’Or, northern Paris. Known as an immigrant neighborhood, the area is considered dangerous. In the 1980s, local residents found children playing on the streets until late at night. Worried that the children might turn to crime, the residents established ADOS to provide the children with a safe place to study and play. The children’s parents worked irregular and late hours and therefore could not keep an eye on their children after school. In this sense, ADOS’ provision of a safe center for the children suited the immigrants’ needs.ADOS also provided remedial tutoring and leisure activities such as going to the cinema and theatre, skating and making videos. ADOS put most emphasis on the leisure activities. By participating in these activities, children experienced a culture other than that of their parents and came into contact with a “French society” different from the one in their neighborhood.To the second generation immigrants and their parents in Goutte-d’Or, the association did not function for school success but rather provided a social safety net that prevented the children from becoming delinquent and allowed them a minimum level of adaptation to French society.
