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.
