This document summarizes research on changing family structures and intergenerational transfers of time and money within families. As lifespans increase and fertility rates decline, populations are aging with fewer children to support older generations. The research examines the time and money older Australians provide to and receive from different generations, and finds that over 60% of those over 50 provide an average of 7 hours per week of practical support to family. This unpaid care work is valued at $36 billion annually, comparable to sectors like mining and retail. Factors like gender, income, and family type influence the amount of intergenerational support exchanged.
