People have positive attitudes toward preserving natural resources, but they may not support policies to limit urban sprawl, which poses significant challenges for sustainable development, as environmental (e.g. increased greenhouse gas emissions), territorial (e.g. spatial segregation) and societal (e.g. accessibility and proximity to services). Suburbanization considered the outcome of macro-level factors (e.g. housing market and housing policy developments). However, the role of micro-level factors at the level of household (e.g. values and lifestyle) is unavoidable.

To limit urban sprawl, policymakers have proposed solutions (e.g. eco-neighborhoods and densification) that may meet the objectives of sustainable development, but not the ones of households’ aspirations (Lotfi, 2012). Many households continue to choose suburbs. Does choosing to live in suburbs necessarily mean an unsustainable behavior?

It is supposed that each type of environment (e.g. suburb) has an ascribed lifestyle, but some studies found that there may be less attachment to concomitant aspects of these built forms, such as use of private vehicles in low-density developments (Myers and Gearin, 2001; Walker and Li, 2007). So, inconsistency between the concomitant and performed lifestyle raises the need for a systematic comparison of lifestyle among those living in different residential settings to establish the link between residential choice and sustainability.

In this context of urban sprawl, this research deals with residential choice and sustainability. The aim is to measure the "degree of fitness" between sustainability of residential location and behavior, by focusing on generated lifestyle by residential choice and its contribution to person-environment (in)congruity. The study area is Québec metropolitan community (CMQ), where suburbanization poses significant challenges to sustainable development. We apply a quantitative approach using the data of the internet survey of "Demain Québec". To date, we have developed an analytical framework for measurement of sustainable environment and sustainable behavior in the context of residential choice.
