This book by Barry McPherson is the fourth edition of Canada's first textbook on aging. Aging as a Social Process is a comprehensive text that elucidates and links the physiological, psychological, and social domains of aging within the context of what are known as individual and population aging. As the title implies, the book focuses primarily on the social processes of aging embedded in the micro-, meso-, and macro-level environments. It therefore balances individual-level experiences and social-structural forces connected to the causes and consequences of aging. It has been updated and expanded to reflect the increasing diversity in aging and the aged and the concomitant growth in research. This is captured through the integration of theory, research, and policy, from multiple perspectives and methodologies, applied to a wider range of substantive issues than in previous editions of the text. For instance, Aboriginal people and aging, homelessness, dating and sexuality, gay and lesbian relationships, end-of-life care, home care, and older drivers are but a few of the topics added or significantly supplemented in this new edition. In particular, I found the inclusion of a chapter dealing with individual and population health a needed and welcome addition. A life-course perspective on these topics that embraces the multiplicity of experience as individuals move through life stages, exposed to different historical and cultural contexts and facing and creating different life choices and chances, connects the material presented in this text.
