Authors: Maria Evandrou, Jane Falkingham, Madelin Gomez-Leon and Athina Vlachantoni ESRC Centre for Population Change and Centre for Research on Ageing Faculty of Social and Human Sciences, University of Southampton Abstract (150 words) Understanding patterns of intergenerational support is critical in the context of population ageing and changes in the policy landscape of health and social care provision. Existing research has usually aŶalysed iŶteƌgeŶeƌatioŶal suppoƌt at a giǀeŶ tiŵe iŶ the iŶdiǀiduals lifeĐouƌse. Hoǁeǀeƌ, the laĐk of empirical data has rendered the study of the dynamic nature of such support a more difficult task. Using data from the 1958 cohort study, this paper examines the extent to which the receipt of help from oŶes paƌeŶts iŶ eaƌly adulthood affects the chances of adult-children to reciprocate with support later in life. Results show that provision of support to parents was associated with having previously received support, although with a gradient of reciprocity. Highly demanding types of help provided to parents respond more to the altruism model (especially for daughters), while less demanding provision of help are more responsive to reciprocity norms (especially for sons).
