Population Health: The New Agenda from Vancouver Coastal Health is a brilliant new video that documents the health impact of social determinants of health; or, in simple terms, why poor people get sick and die while higher-income people live longer and healthier lives. It provides a powerful complement to Poverty Is Making Us Sick, recent research from the Wellesley Institute on the links beween income and health; and also Sick and Tired, a study on low-income and poor health in Ontario.
