Understanding Collective Identity in Virtual Spaces: A Study of the Youth Climate Movement.

How does collective identity form in virtual spaces and what role do hashtags play? This paper takes advantage of a unique dataset that includes surveys from activists who organized the nationally coordinated climate strikes in the US that began in spring 2019 to answer these questions. Building on the research about collective identity formation online and the role that hashtags play, we employ social network analysis to assess how collective identity forms online over three waves of protests. In particular, we analyze how activists involved in the youth climate movement used hashtags to project their collective identities and create collective narratives. Our findings show how hashtags use varied over the period of our study, in some cases indicating the formation of a thin collective identity. They also show that there are patterns in the ways hashtags are employed by activists in the movement that suggest the formation of subaltern narratives among those affiliated with youth-led groups. Our paper concludes by considering how this finding helps us understand collective identity in virtual spaces and the role that hashtags play more specifically within social movements.
