Housing forms a large part of the Australian economy and is an integral part of people’s well-being. In addition to serving a basic human need for physical shelter, and contributing to physical and psychological health and emotional security, it is a key determinant of people’s wealth and financial security in old age. The growing longevity and aging of Australia’s population, as well as other structural and demographic changes, elevate the policy imperative to understand what drives the housing decisions of older people and the consequences for their wellbeing.
