This book reviews social protection from a much wider perspective, extending coverage of social protection both in terms of the proportion of the population with excess to the social protection scheme, and the types of risks faced by the households and by society as a whole. It also offers a focused and detailed analysis on issues such as: the concerns of sustainability, structure of payout phrase and coverage for informal workers. It also covers issues in pension and health care arrangements in depopulating high income countries of Japan and Korea to countries with large populations but low coverage of formal social protection such as China, India and Indonesia.
