Self-assessed Physical and Mental Health and Fertility Expectations of Men and Women Across the Life Course.

The fertility expectations of older women and men are becoming increasingly important for understanding fertility dynamics, given the increasing share of births after age 30. Because most health conditions deteriorate with age, understanding the relationship between health and fertility expectations is essential. We investigate whether changes in self-assessed general, physical, and mental health are linked to revised fertility expectations and how these associations vary over the life course. Drawing on a large longitudinal dataset for Australia, we demonstrate that across each health indicator, self-assessed poor health corresponds to lower fertility expectations and that a deterioration (or improvement) in self-assessed health coincides with a decrease (or increase) in men's and women's expectations of having a child. Individuals adapt their expectations more in response to physical health changes if they are older, and mental health conditions at younger ages appear relevant to men's fertility intentions. The results highlight that general, physical, and mental health are crucial drivers of changes in fertility plans, emphasizing the importance of integrating health considerations into future theoretical frameworks and empirical analyses of fertility.
