Abstract
This article explores how theories of diversity and intersectionality can improve our understandings of the lives of older lesbian, gay and bisexual (LGB) adults. In so doing, it argues that theories of diversity help us to understand both the structural constraints and the advantages that may arise from being an older LGB adult. However, these theories are unable to fully account for differences that may exist within this social group. In order to address this omission, we argue that we need to move beyond a focus on diversity per se, to incorporate the multiplicity of identities suggested by intersectionality theory. We conclude by assessing the implications of this debate for policy and research. Throughout the article we draw on existing research as well as our own empirical studies with older LGB adults.
