Based on a survey conducted by the CEPS/INSTEAD and the Forum Europa foundation, this article analyses the cross-border residential mobility phenomenon and its impact on daily travel. Conducted in spring 2008, this survey concerns employed workers residing initially in Luxembourg and having settled in a neighbouring country between 2001 and 2007, while keeping their job in the Grand Duchy. For a large number of them, moving across the border was a way of finding a larger home or even becoming home-owners. Nevertheless, analysis of daily trips shows that the great majority of these people have had to make a large number of concessions in terms of mobility to get the sort of housing they want. This applies particularly to their daily commuter journey, the average distance of which has doubled, thereby increasing their reliance on the automobile. Outside work, the location of other daily activities is modified by the change of residence. Compound spatial statistics indicators can be used to analyse the reconfiguration of the locations of these activities. Despite the relocation of many such activities around the new place of residence, a certain inertia can be seen in behaviour in that people maintain almost one in three of them in Luxembourg. The dispersion of activity spaces increases for some of those surveyed. This dispersion linked to the proportion of activities transferred to the country of residence varies sharply according to nationality, being higher among Luxembourgers and the Portuguese. People originating from the border regions and returning to their country of origin also keep almost one-quarter of their activities in the Grand Duchy, showing both the importance of the place of work in structuring the spaces of daily life and a spatial capital already demonstrated in working people residing in Luxembourg.
