The characteristics of children’s homes and family living arrangements, being a large part of their physical and social environment, have important influences on their development and wellbeing (Bronfenbrenner & Morris, 2006). A recent scoping study (Dockery et al., 2010) identified Growing Up in Australia: The Longitudinal Study of Australian Children (LSAC) as a useful source of data for analysing housing and child developmental outcomes. This chapter describes three aspects of housing that are expected to be important for children’s outcomes: housing mobility, tenure and overcrowding (Dockery et al., 2010).
