The Peterson-KFF Health System Tracker provides clear, up-to-date information on trends, drivers and issues that impact the performance of the system. It also illustrates how the U.S. is performing relative to other countries and how different parts of the system are performing relative to one another. A partnership of the Peterson Center on Healthcare and the KFF, the Tracker’s work goal places a heavy emphasis on data and evidence, addressing key questions through collections of charts, which provide data with additional context and synthesis of the latest research and developments. The Tracker also provide regular insight briefs for a more in-depth look at topical questions.
