Data presented in the Boston Public Health Commission's Health of Boston report routinely demonstrates that Boston's Black and Latino residents experience higher levels of chronic disease, mortality, and poorer health outcomes than White residents. These persistent health disparities are driven by the interaction of several factors including racism, living conditions, physical environment, socioeconomic status, food security, lifestyle, available health services, and existing health policies. The data provided offers a broad picture of the health experience of our city, identifies individuals and communities at greatest risk for certain conditions, and stimulates discussion among individuals within our communities. Understanding the city's diversity is essential to developing policies and strategies that address health equity in Boston.
