Unnatural Causes: Is Inequality Making Us Sick? is a four-hour documentary series, broadcast nationally in the United States on PBS in spring 2008, that examines the role of social determinants of health in creating health inequalities/health disparities (which the film considers health inequities) in the US. Based on extensive research by a wide variety of academics, public health experts and medical practitioners, the seven-part series explores how class and racism can have greater impacts on one's health outcomes than genetics or personal behavior.
