The return to work of the RMI recipients takes more time in municipalities of low density and high density than in other municipalities. This paper uses different statistical sources to explain why. The added value of the paper concerns mainly rural communes. Rates of participation of RMI recipients in back-to-work financial support is calculated from the file of mandatory benefits and welfare action by the Caisse Nationale des Allocations Familiales, at a municipal level. Rates are explained by the characteristics of the communes coming from the Population Census (National Institute of Statistics and Economic Studies) and by some indicators of new firms drawn from the SIRENE register. These data are then matched with those of the Municipal Inventory, which provides information on facilities and services in each municipality. The results are that local jobs produced by local infrastructures and services facilitate the return to work of the RMI recipients.
