The analysis reported here aims to establish the household prevalence of caregiving in Australia, drawing on a large scale, longitudinal survey conducted as part of the Victorian Carers Project. Comparisons are made with a national survey conducted by the Australian Bureau of Statistics and with Canadian and U.K. findings. Three aspects of caregiving are investigated: reported household prevalence, taking account of differences in definitions used in various surveys; the extent of intergenerational exchanges involved in caregiving; and the time dimensions of caregiving, in terms of duration and patterns of cessation of caregiving over time. A high degree of consistency is found in prevalences of caregiving and implications for the development of policies and programs to support caregivers are raised concerning levels of caregiving, approaches to identifying carers, targeting of services and promotion of caregiving, and the spread of the experience of caregiving across the lifecycle and between generations.
