"Improving Global Health" is the third in a series of volumes Patterns of Potential Human Progress that uses the International Futures (IFs) simulation model to explore prospects for human development: how development appears to be unfolding globally and locally, how we would like it to evolve, and how better to assure that we move it in desired directions. Earlier volumes addressed the reduction of global poverty and the advance of global education. Volume 3 sets out to tell a story of possible futures for the health of peoples across the world. Questions the volume addresses include: What health outcomes might we expect given current patterns of human development? What opportunities exist for intervention and the achievement of alternate health futures? How might improved health futures affect broader economic, social, and political prospects of countries, regions, and the world?
