Data in movement: the social movement society in the age of datafication

Data has increased currency in contemporary activism and has become an integral part of the action repertoire of today's social movements. But data and data infrastructure are not only tools to support a movement's struggle: they are constitutive parts of the environment in which movements operate, and objects of contention in their own right. These developments challenge scholars of social movements and collective action. How are movements changing under the pressure of datafication? What 'new' mechanisms, actors and tactics meet the growing demand for citizen participation in an increasingly datafied society? Is social movement scholarship 'fit' to capture and interpret this evolution? This theoretical article puts social movement studies in dialogue with critical data studies with the aim of encouraging a much-needed cross-pollination. It advances the notion of 'datafied movements' to address the novel structural condition of contentious politics in the age of datafication and to explore the socio-technical, systemic effects of data and data infrastructure on movement dynamics. It reflects on how five key social movement dynamics, and the related elements in the conceptual toolbox of social movement studies – group formation, opportunity structures, action repertoires, meaning work, and collective identity – are altered by datafication and the advance of intelligent systems in society. In so doing, this article charts the building blocks of a future-proof research program in social movements.
