Association Mohamed Boudiaf de O.fayet seeks to recreate the social bond on the territory of a périurbaine commune of the wilaya of Algiers of 25 000 inhabitants. Its population of the rurbaine type, saw a social fracture having for origin the heterogeneity of the social layers which make it up. Until the Seventies, the commune was a colonial borough with purely wine vocation with a farming population. In the Eighties, the common one knew the massive arrival of urban populations, with the favour of the construction of collective sets HLM and individual real co-operatives. Decade 90 will be marked by an exodus of rural populations originating mainly in Wilaya de Médéa. These social groups live in autarky. The 3e group is completely marginalized.
