Partnership Histories Shape the Grandparenting Happiness Bonus

Abstract

Evolutionary theory predicts that returns on investments in family relations will vary by sex and life stage and that there can be a trade-off between mating and (grand)parenting. Family sociology has shown that whereas couple relations are central to happiness in older age, the effects of grandparenting are more mixed and context dependent. Here, we merge these two perspectives and study how partnership histories over the life course relate to happiness among Europeans aged 50+ and whether grandparental investment moderates these associations. Of particular interest is whether there are signs of trade-offs, cumulative benefits, or compensatory benefits between the type of couple relations and grandparenting in postreproductive age.We employed the Survey of Health, Ageing and Retirement in Europe with data from 26 European countries and Israel for the years 2004–2020. The analyses distinguish between respondents who are in their first, second, or third union through marriage or cohabitation; are divorced; are widowed; are living apart from a partner; or are single. We investigated how quality of life and life satisfaction are associated with these seven types of partnership histories and whether the associations are moderated by grandparental status and provision of grandchild care.Europeans with a partner, and especially those in their first union, were happier than those in other partnership groups, and grandparents were happier than individuals without grandchildren. Grandparental investment was associated with being happier in most partnership groups. The “grandparenting bonus” was greatest among unpartnered respondents, suggesting a compensatory effect. We found no signs of a cumulative effect, nor of costs to happiness from grandchild care.Our results illustrate how reproductive strategies over the life course shape happiness returns to grandparenting. Being a grandparent and, especially, providing care for grandchildren may compensate for the lower happiness associated with the loss or lack of a partner.
