Residential Choice and Households Strategies in the Grand Paris Region

Households strategies relative to residential choice in the grand Paris area are developed in this paper. The question of the presence or not of a trade-off between transport and housing expenditures is tackled.


With the increasing concerns about global warming and the rise of energy prices, the issue of land-use planning, and more precisely of the linkage between transportation and land use, has become a major topic of interest. Previous transport policies in many European cities, mainly in favour of car use, have led to urban sprawling, which is well known to come along with an increase in energy consumption. Therefore, several projects such as Scatter in Brussels or Simaurif in Île-de-France have been undertaken to deepen the knowledge of the links between transportation supply and residential choices.

The issue of the interactions between transportation and residential choices has been tackled by a number of researchers. Notably, the question of whether the distance to the Central Business District has an influence or not on the housing price, as suggests the urban economic theory, has largely been addressed. Nevertheless, most studies focused on the impact of transportation supply on housing prices, and did not consider the issue from the household point of view.

In this paper, we adopt a broader approach by addressing the matter of household strategies in residential choices. In standard urban economic theory, the household maximises its utility under a budget constraint, which leads to a trade-off between transportation costs and housing costs. The main objective of this article is to evaluate whether households proceed to such a trade-off or not. To do so, we bring forth a geographical analysis studying households transportation and housing budgets in the grand Paris area (France). The relative weight of each budget in the global budget of the households, and the presence or absence of a relationship between the two, will be highlighted.

In order to account for the great variability of households strategies according to their characteristics, the income and the size of the household will be used as control factors in the subsequent analysis, while the ?profession et catégorie socioprofessionnelle? (profession or socio-professional category) will allow us to test the robustness of our results. Strategies will be detailed in terms of choice of location, surface, and opting for rental or ownership.

Mobility costs will be computed thanks to the Enquête Globale de Transports, a regional household trip survey carried out in the Île-de-France and giving very detailed information about mobility practices on a daily basis. Housing budgets of the households on the other side will be derived from the combination of several sources, mainly the Enquête Globale de Transports, which gives comprehensive information about the size and the characteristics of the households, their location, their income, the surface of their apartments (but no information on housing expenditures), and the notarial database, which will provide us additional information about housing costs.

The paper will be divided into six sections. An overview of the different databases is developed in section 1. Section 2 and 3 present the methodology used to compute transport and housing expenditures. The geographical analysis of households strategies is undertaken in section 4, while section 5 evaluates the robustness of our results. Section 6 offers some conclusions.
