Under-Served brings together the perspectives of academics, front-line health care providers, and policy-makers to examine the historical, political, and social factors that influence the health and health care of under-served populations in Canada, focusing particularly on Indigenous, inner-city, and migrant populations. This vital text broadens the traditional determinants of health?the social, economic, environmental, and behavioural elements?to include factors like family and community, government policies, mental health and addiction, homelessness and housing, racism, youth, and LGBTQ identity.
