"The study aims to understand the transformation of both uses and representations of ""auto-mobility"" for elders aging suburb. The complexity of residential experience and meanings of “home” have been explored in relation with a decreased daily mobility. Both uses and representations of seniors’ mobility have been analyzed under the light of lifestyle. In old age, the mobility must be addressed beyond the concept of displacement. Mobility is part of the residential experience by which the elders develop self-identity, participate in social world, and emotionally attach themselves to lifestyle. This enables the individual to keep a status of autonomy and independence. In that context, the daily mobility of 22 residents of Post-War suburbs in the agglomeration of Quebec in Canada has been explored in 1999 and in 2006. On the basis of changes in their mobility uses over nearly seven years, these aged people were preliminarily selected from a 102 non-random sample. These 14 men and 8 women were aged from 62 to 89 years at the second series of interviews. According to a psychosocial approach, the subjects were interviewed in their homes with semistructured questionnaires. Subjects were able to freely discuss their thoughts on both their daily activities, places visited in the city, and their representations of automobile, urbanity and ageing. The results partially confirm the 1999 hypothesis in regards to both daily mobility’s evolution and adaptation. Some elders increased their activity space, while others saw their mobility shrink on the territory, and some others faced immobility. Freedom of choice appears as a key-component to a positive residential experience. The built environment and the lifestyle are related to both changes and adaptation mobility uses. Individuals less mobile easily adapt their lifestyles while the others, more mobile, pushed their mobility to the limits of both their physical abilities and their socio-economical resources. In the dynamic of these strategies, the inertia of both spatial and social uses, the emergence of autonomy limitations, the caregivers availability, and the ""déprise"" of social life induced five residential experiences: 1) urban space shrinking, 2) urban space splitting up, 3) urban space losing its spatial references, 4) urban space lived by proxy, and 5) urban space entering at "home"."
