This book examines some of the challenges facing older people, given a context of rising life expectancy, cuts to the welfare state, and widening economic and social inequalities. It explores precarity and ageing from a range of disciplinary backgrounds, critical perspectives, and contexts. Although cultural representations and policy discourses depict older people as a group healthier and more prosperous than ever, many older people experience ageing amid insecurities that emerge in later life or are carried forward as a consequence of earlier disadvantage. The collection of chapters develops a distinctive approach to understanding the changing cultural, economic and social circumstances that create precarity for different groups of older people. The aim of the book is to explore what insights the concept of precarity might bring to an understanding of ageing across the life course, especially in the context of the radical socio-political changes affecting the lives of older people. In doing so, it draws attention both to altered forms of ageing, but also to changing social and cultural contexts, and realities that challenge the assumption that older people will be protected by existing social programmes or whatever resources that can be marshalled privately. What risks and insecurities do older people face in a time of both increased longevity and widening inequality? This edited collection develops an exciting new approach to understanding the changing cultural, economic and social circumstances facing different groups of older people. Exploring a range of topics, the chapters provide a critical review of the concept of precarity, highlighting the experiences of ageing that occur within the context of societal changes tied to declining social protection. Drawing together insights from leading voices across a range of disciplines, the book underscores the pressing need to address inequality across the life course and into later life. This edited collection develops an exciting new approach to understanding the changing cultural, economic and social circumstances facing different groups of older people. The chapter sets the foundation for the exploration of precarity and aging from a range of disciplinary backgrounds, critical perspectives, and contexts. It begins by outlining the concept of precarity and precariousness in fields such as geography and labour studies, examines how the concept has been applied to late life, and considers its relevance to the field of ageing. It establishes precarity as lens for drawing attention to insecurity and risk in later life. The chapter then poses a series of questions to guide reflection and ground the debates pursued by authors throughout the book, followed by a brief overview of the chapters ahead.
