Shape-shifting versions of class in Australia and the pursuit of equity in public health

The COVID-19 pandemic and current cost of living crisis have highlighted socioeconomically patterned health disparities, bringing renewed focus on equity in public health. Despite political rhetoric invoking cultural narratives of egalitarianism and opportunities for class mobility, social class remains a significant factor in health outcomes in the Australian context. For social scientists, class (despite robust critiques) is a key analytical concept that has been theoretically broadened to encompass social and cultural practices (habitus). In public health, however, concepts of social disadvantage have expanded toward frames such as health equity and socioeconomic status in ways that can obscure 'class' and habitus. Understandings and operationalization of concepts of class and equity not only impact collaborative and interdisciplinary relationships, but also the framing of public health problems and health promotion interventions and policies. In this article, we draw on our experiences as anthropologists conducting ethnography in and of Australian health promotion programs to map and re-evaluate the intersection of concepts of social class and equity. We trace how representations of class emerged in these programs, and the versions of class and equity that materialized across different public health contexts. We argue for a conceptual repositioning of class that recognizes its shape-shifting qualities and of its materializations in different politics, disciplines and everyday contexts. In doing so, we highlight 'class' as a salient dimension of the design, implementation and evaluation of health promotion programs.
