The Commonwealth Fund’s Medicare Data Hub provides up-to-date facts, research, and analyses about Medicare, a program that provides health coverage to more than 60 million Americans — about one in six people — including older adults, people with serious disabilities, and other vulnerable individuals. A resource for policymakers, researchers, health care providers, consumer advocates, and journalists, the data hub is intended to spark and inform discussion about issues that affect health care for Medicare beneficiaries and other Americans.
