More precisely, the question at stake is how to integrate the project of the various intercommunalites, w'ith their own level of constraints and local solutions, into a larger scale than single municipalities. By doing so, these individuals are able to bring local ideas and projects to a supra level, and have the potential to overcome difficulties based on the differences between territories. For example, the north littoral is filled with elderly people, whereas in the south there are mostly younger couples with children. But most of all, the main question is often about the opposition between Nantes and Saint-Nazaire on the one hand, and on the other hand, the other communes.
