Essays on longevity, ageing and informal care.

Summary A number of issues arise from the context of demographic ageing in Europe, the prevalence and generalisation of which on the European continent make it unprecedented. Thus, the increase in the number of elderly people, and more particularly, the number of elderly people in a situation of dependence, democratizes the question of their care and the role of each of the stakeholders. This thesis proposes to study the issues related to aging and the provision of informal care. The first chapter studies the relationship between mortality and income. The second chapter examines the motivations of children to become informal caregivers for their parents. The third and fourth chapters analyze, respectively, the impact of informal care on the health of the caregiver and that of his or her partner.
