The capability approach has been developed by Amartya Sen, Martha Nussbaum and others as a human-centred normative framework for the evaluation of individual and group well-being, quality of life and social justice. Sen and Nussbaum’s ideas have influenced global, national and local policy and have been further developed in a number of academic disciplines, but so far have remained largely unnoticed in sociology. This article examines recent capability-informed theories and empirical applications in the sociology of human rights and other academic fields adjacent to sociology, focussing on examples of social policy studies in the fields of welfare, the labour market, health and disability, and education. The article outlines several potential areas in which capability-informed frameworks are relevant for critical social theory, public sociology and global sociology.
