Gerontology is the scientific study of the sociological, psychological, biological, and economic aspects of aging and the problems of older adults. It is an interdisciplinary field that draws on various disciplines to understand the aging process and the experiences of people as they grow older. Social gerontology, a specialised area within gerontology, specifically examines the social (and sociological) aspects of aging, focusing on topics such as social roles, relationships, social inequalities related to age, and the impact of social structures on the aging experience. Researchers in gerontology also study the psychological changes associated with aging, as well as the biological processes of senescence and the economic challenges and opportunities faced by older populations. The field of gerontology plays an increasingly important role in addressing the needs and concerns of aging populations in societies around the world.
