The Second Canadian Edition of Adult Development and Aging takes a “successful aging” perspective to approach topics related to the aging individual within Canadian society. The text explores psychological theory of aging with an emphasis on research being done in Canada, which is highlighted in the How Do We Know? feature boxes in each chapter. Beyond theory, the text considers the experience of aging for older adults in Canada today, especially the baby boom generation who are entering older adulthood and who will all be older adults by 2030. This demographic shift has important implications globally, but also brings unique challenges and opportunities within a Canadian context. This Canadian textbook provides in-depth coverage of the major issues in the psychology of adult development and aging from a Canadian perspective and considers how Canada’s diverse population is affected by issues related to aging such as health and healthcare, longevity, relationships, work, housing, and end of life issues that are unique to this country. Each chapter has been thoroughly reviewed and updated to reflect current demographic changes in Canada using up-to-date data from the 2021 Canadian census. Topics reflect the diverse experiences in Canada, including Indigenous peoples, racialized individuals, and immigrants. Throughout the text, particular attention has been paid to the effects of COVID-19 and the effects of various types of discrimination and bias on the experience of adult development and aging. A positive approach to aging is taken throughout the book and highlighted in Successful Aging feature boxes describing real Canadians
