RWJF asked the Health and Medicine Division of the National Academies of Sciences, Engineering, and Medicine to help delineate the causes of and the solutions to health inequities in the United States. The focus of this report is on what communities can do to promote health equity and on the broader policy context and contributions of stakeholders that can support communities. The committee reviewed the root causes and structural barriers that need to be overcome, community examples to address health inequties, as well as policies to support change at multiple levels.
