We are delighted to release the ROSEnet Briefing Paper Series. The first five of these Briefs considers each of the different domains of exclusion that can occur in later life. The 6th Brief focuses on multidimensional old-age social exclusion and the ways that these different domains of exclusion can interact and impact on older people’s lives. Each Brief presents an analysis of research evidence, and policy challenges, and outlines a key set of policy messages to reduce exclusion in older age. The policy briefs are available here.
