Several European and North American cities are now sprawling metropolitan territories. In the last thirty years, the distance between the residence and the geographical center of these metro areas has increased significantly. So much that the word sprawl is being replaced by concepts such as dispersion, diffusion and fragmentation to reflect metropolitan areas defining an amorphous and discontinuous territory, now reaching the countryside. In this context, how is car dependency experienced by aging adults? This symposium compares the auto-mobility behaviors of elderly living in suburban and periurban areas of German, Italian, Mexican and Canadian metropolitan areas, as well as the meanings and representations of the city as well as of vehicular mobility for these older adults. The relationship between the residential location, on the one hand, and the loss of corporal and motorized mobility, on the other hand, are explored through empirical evidence from qualitative and quantitative studies conducted in these different countries. Similarities and differences are pointed out in relationship to local urban form and the level of services, amenities and public transportation. The challenges of aging in periurban areas as well as avenues for facilitating it are discussed in conclusion. Four communications will be presented during this symposium. The session is designed to be paired or associated with a companion symposium on children and teenagers' mobility for which another proposal has been submitted.
