Ausführliche Beschreibung

Maternal and paternal ages at birth are increasing across the developed world, giving rise to concerns about the individual- and population-level effects of fertility postponement on the health of parents and their offspring. We analyze how parental age at childbearing is associated with individual-level outcomes for both parents and their children, which mechanisms might be responsible for these associations, and whether these relationships are causal. We distinguish the separate contributions of parental biological aging, resource accumulation, and changing period conditions to the association between parental age and child outcomes.

We study a wide range of outcomes for the offspring of older parents, including their cognitive ability, health, education, career success, and mortality. We also examine whether the age at childbearing and the number of children affect the mortality of the parents themselves. We use methods that compare siblings to account for unobserved parental characteristics. To cover a wide range of contexts in which the relative importance of aging, resources, and period conditions might differ, we use large population-based samples from the USA, register-based data from Scandinavian countries, Demographic and Health Surveys, and other sources.
