This study’s novelty lies in the experimental measuring of place of residence effects derived from a multi-level protocol that allows one to discern the effects at different levels of spatial aggregation: large administrative units (the "département" in France), municipalities, and neighbourhoods. This protocol was applied to two administrative units (Seine-Saint-Denis and 3 the city of Paris) in the Paris region, which are geographically close but quite different in terms of socio-economic status, in order to compare the effects associated with three types of neighbourhoods: favoured areas, intermediate reputation areas , and disadvantaged areas.
