There has never been more unequal access to housing and housing wealth among Australians. The consequences of these inequalities are different for current and future generational cohorts, a little-researched source of inequity. The project aims to use never-before analysed combinations of datasets and new data on Australian housing conditions to model these consequences, and to evaluate both individual and national benefits of housing interventions across generations. We will use powerful causally focused methods now available, to disentangle the drivers and health consequences of the intergenerational housing gap. The anticipated results would give policymakers robust evidence and direction for tackling this defining problem of our time.
