As the baby boomers enter later life, unprecedented numbers of women are retiring. The first generation of women to encounter retirement since its institutionalisation as an expected male life course transition in the mid‐20th century, these women are leaving the labour force at a time when the meanings associated with “retirement” are changing. Longer life expectancy, improved health outcomes, and transformations in work driven by globalisation have produced greater diversity in when, why, and how people exit the labour force. Many boomer women are disadvantaged in later life by their histories of discontinuous employment and care‐giving. Consequently, we argue, opportunities to engage in “retirement” projects of their own choosing are unequal across this population. This essay reviews qualitative studies in sociology that examine boomer women's experiences of retirement and is organised in terms of the three main approaches that inform this under‐studied field: critical/feminist gerontology, identity theory, and life course approaches. Based on our review, we posit the need for socially inclusive research, beyond the prevailing emphasis on White, middle‐class professional women; more studies examining the impact of earlier life course transitions on women's later years; and attention to the effects of “successful ageing” discourses on women's lived experiences.
