LOCAL HOUSING-MARKET AND THE SOCIAL REORGANIZATION OF SPACE - THE CASE OF THE LILLE CONURBATION

This article shows that evolution in the housing market can change the location of social groups. Residential mobility at the local level, i .e. intra-urban migration of households, is examined. Morphological an d social specificities of the spaces which accommodate them are taken into account. In the 1970s, household migratory flows went from the ol d overpopulated neighbourhoods towards the first couronne of the Lille agglomeration. But during the last decade, residential mobility came in the first place from tenants of social housing in the first couronn e who began to move to housing in the second couronne. Intra-urban mig ration changes the spatial distribution of households. They are organi zed in a system of unequal intermunicipal exchanges, which forms part and parcel of the segregative forces at work in local housing markets.
