Background: An aging population has increased the prevalence of multigenerational caregiving (MGC), defined as unpaid care for an adult while having a dependent child in the household. Policymakers are simultaneously promoting labor force attachment in response to population aging, which may conflict with MGC status.

Objective: This research provides estimates of the probability of MGC status and its relationship to labor force attachment.

Methods: A balanced panel of respondents from nine waves (2005−2013) of the Household, Income and Labour Dynamics in Australia (HILDA) survey data has been used to estimate point-in-time and lifetime probabilities of MGC status for women and for men, and rates of labor force participation and part-time employment prior to, during, and after MGC status.

Results: Few adult women (2.3%) and men (1.1%) report MGC status at any point in time. Estimated lifetime probabilities of MGC status are 57.1% for women and 34.6% for men, and rates are higher for women and men out of the labor force pre-MGC status. Comparing pre- and post-MGC periods, women’s labor force participation rises by an estimated 9 percentage points, mainly due to an increase in part-time employment.

Conclusions: A majority of Australian women and many Australian men can expect to take on multigenerational caregiving responsibilities during their lifetime. While long-term labor force participation is not reduced by these responsibilities, they may increase the concentration of women in part-time employment.

Contribution: Prior studies capturing MGC status are limited by age, gender, or are not longitudinal and our research note attempts to broaden our understanding of the impact of carer status.
