Worldwide, the single fastest –growing age group is adults age 60 and older, and the global population of adults age 80 and older is expected to increase dramatically with every decade. Most health systems around the world are ill-prepared for this changing demographic. While these are important issues for places like the U.S. and other high income countries, they are even more pressing for China, India, and other nations which are confronted with aging populations yet lack concerted efforts and resources to prepare for an aging world. The Institute is launching a major new initiative that directly tackles these issues, bringing together experts from a variety of fields (technology and computer science, design, and law, just to name a few) and from around the world to lay out both a research and a policy agenda. The challenges of caring for an aging population are large and complicated, and now is the time to start working on them.
