On March 21, 2019, the Roundtable on Population Health Improvement of the National Academies of Sciences, Engineering, and Medicine convened a 1-day workshop to explore the broad and multidisciplinary nature of the population health workforce. Workshop participants explored methods for facilitating a population health orientation/perspective among public health and health care leaders and professionals; framing the work of personnel such as community health workers (CHWs), health navigators, and peer-to-peer chronic disease management educators within the context of population health; and leveraging the competencies of public and private sector workforces, such as education, transportation, and planning, that are working to include a "health in all policies," community livability, or well-being orientation in their activities. This publication summarizes the presentations and discussions from the workshop.
