SHARE data has informed a study commissioned by the Directorate-General for Employment, Social Affairs and Inclusion (DG Empl) on the incidence and costs of informal long-term care in the European Union. The outcomes of this “Study on exploring the incidence and costs of informal long-term care in the EU” have been published in June 2021. The study aimed to develop a common understanding of informal care, to estimate the number of people providing informal long-term care and to analyse their characteristics. Further, it estimated the costs associated with the provision of informal long-term care, both for individuals and states. All of this information was backed up with analyses based on SHARE data.
