Handbook of Aging and the Social Sciences, Eighth Edition, presents the extraordinary growth of research on aging individuals, populations, and the dynamic culmination of the life course, providing a comprehensive synthesis and review of the latest research findings in the social sciences of aging. As the complexities of population dynamics, cohort succession, and policy changes modify the world and its inhabitants in ways that must be vigilantly monitored so that aging research remains relevant and accurate, this completely revised edition not only includes the foundational, classic themes of aging research, but also a rich array of emerging topics and perspectives that advance the field in exciting ways. New topics include families, immigration, social factors, and cognition, caregiving, neighborhoods, and built environments, natural disasters, religion and health, and sexual behavior, amongst others.
