In October 2016, the National Academies of Sciences, Engineering, and Medicine’s Roundtable on Population Health Improvement hosted a workshop to explore sustainable financing structures that reflect a recognition of the health and non-health factors that shape the well-being of U.S. communities. The goals of the workshop were to learn from the long-term, sustainable financing strategies used in other sectors, to explore how those approaches could be applied to population health, and to consider structures that work across sectors. This publication summarizes the presentations and discussions from the workshop.
