<DIV>In 2012, organizations including the United Nations, G20, and International Labor Organization adopted a global policy initiative known as the social protection floor—a set of measures designed to ensure that all people have access to essential health care and income security over their lifespan. This book, authored by a leading authority on global social policy, traces the emergence of the social protection floor and identifies the major influences that shaped it: shifts in the world’s social structure, processes inside international institutions, attempts by global actors to create change, and shifts in the global conversation about social protection. </DIV>
