Building on previous National Academies of Sciences, Engineering, and Medicine workshops that explored how safe and healthy communities are a necessary component of health equity and efforts to improve population health, the Roundtable on Population Health Improvement wanted to explore how a variety of community-based organizations came together to achieve population health. To do so, the roundtable hosted a workshop in Oakland, California, on December 8, 2016, to explore multisector health partnerships that engage residents, reduce health disparities, and improve health and well-being. This publication summarizes the presentations and discussions from the workshop.Table of ContentsFront Matter1 Introduction2 Community-Driven Approaches to Building Healthy Communities3 Improving Health Through Equitable Transformative Community Change4 Engaging Communities in Building a Culture of Health5 Building and Sustaining Equitable Community Partnerships6 Reflections on the WorkshopAppendix A: ReferencesAppendix B: Workshop AgendaAppendix C: Communities of Solution: A Working Model Based on Scale and Community Bright Spots Developed by 100 Million Healthier LivesAppendix D: Speaker and Moderator Biographical Sketches
