In the current environment of deepening class and income inequality, it is essential to understand the socio-economic conditions that shape the health of individuals and communities. Now in its third edition, Dennis Raphael’s Social Determinants of Health offers a comprehensive discussion of the primary factors that influence the health of Canada’s population. This seminal text on the social determinants of health contains contributions from top academics and high-profile experts from across the country. Taking a public policy approach, the authors in this edited collection critically analyze the structural inequalities embedded in our society and the socio-economic factors that affect health, including income, education, employment, housing, food security, gender, and race. The thorough updates to this edition include a greater focus on the political mechanisms that explain the distribution of the social determinants of health and additional material on public policy, early childhood education in Canada, and the determinants of Indigenous peoples’ health. Rich in pedagogical tools including critical thinking questions and lists of recommended readings and online resources, this book will actively engage students and researchers alike.
