A powerful force that sets the stage for health inequities is racial and economic segregation. Segregation, in combination with patterns of disinvestment and neglect of segregated communities, concentrate poverty and excludes and isolates communities of color from the resources needed for socioeconomic equality and health. Maps can be a powerful tool to help show why and how investment in communities - or their absence - shape health. To understand and harness the power of maps and mapping tools, the Joint Center Health Policy Institute, and the Opportunity Agenda are pleased to share with you a report, User's Guide: Using Maps to Promote Health Equity, that reviews some of the most promising applications of maps and mapping tools for health equity and will provide recommendations to advance the field.
