Considering that gerontology must study elderly persons within the wider context of society's dynamic processes, as well as with a view of policy responses, this book by Beaujot is to be recommended. Demographic processes underlying the growth of the Third Age in Canada are presented in a clear, non-technical way and their policy consequences are analysed thoroughly. All the chapters are of interest to gerontologists, but particularly chapter 2 on health and mortality, chapter 7 on aging, parts of chapter 6 dealing with an aging workforce, and of chapter 8 which is devoted to the aging of households, not to mention chapter 4 on migration, which is often considered a solution to fertility decline and aging. On most subjects differing points of view are given their fair share, and the author presents his own views and policy options.
