Health in All Policies: A Guide for State and Local Governments was created by the Public Health Institute, the California Department of Public Health, and the American Public Health Association in response to growing interest in using collaborative approaches to improve population health by embedding health considerations into decision-making processes across a broad array of sectors. The Guide draws heavily on the experiences of the California Health in All Policies Task Force and incorporates information from the published and gray literature and interviews with people across the country. The guide was developed through funding from the American Public Health Association and The California Endowment.
