This policy brief provides cross-country evidence on the incidence of loneliness among older adults (50+) in the EU and an analysis of the risk factors for loneliness for this group of individuals. It also assesses the association between loneliness and a range of health outcomes, both physical and mental. Mapping loneliness across EU Member States, identifying the risk factors for loneliness as well as understanding its health related implications may be of guidance for policymakers for the design and implementation of effective intervention to address loneliness.
