Grandparenting is an important dimension of family caregiving over one’s life course, playing a vital role in the intergenerational relationship and family well-being (Xu & Chi, 2015). Grandparenting can provide emotional support, and love, and includes provision of instrumental support, such as in meal preparation, the transmission of cultural/social value, and often involves primary childcare when the parent is absent. In Asia, grandparents’ contribution to childcare, and most likely housework, carries more weight than any other region due to the greater prevalence of three-generation households, building on traditional values of family care and its concomitant economic value. However, how many older people in Asia provide care for grandchildren, what their demographics and socioeconomic characteristics are, and what their caregiving looks like remain relatively unknown. This paper estimates the prevalence of coresident grandparenting and describes the grandparent characteristics in Asia using the two international surveys. Then it reviews the literature primarily from East-Asian and South-East Asian countries, on the effects of grandparenting on health and well-being, and intergenerational solidarity. Based on the quantitative and qualitative evidence, relevant implications for policy and parenting education will be discussed.
