Certain territories have particularly high unemployment rates and have not been successful in modernising their productive apparatus, even though they are sometimes geographically close to more dynamic regions. How can such social fragmentation be explained? Economic analysis has shown that on the one hand households are deeply attached to their place of residence and not familiar with the economic opportunities that exist elsewhere, and that on the other, companies struggle to recruit when they invest in less dynamic areas. Numerous initiatives have been launched by public actors at the local and national levels to attempt to bring workers and jobs together. However, whether this is a question of making areas more attractive or assisting households' residential mobility, it is clear that these policies are often not very effective. What if, in the face of such overall negative results, the solution was to be found in the availability of real estate?
