Existing research explores safety among young adults as a complex phenomenon in diverse social spaces. Nonetheless, it largely approaches perceptions of unsafety and safety strategies as discrete individual action. In this paper, we show how safety is created through the social interactions between young activist groups and their main target or audience, young adults. Our study aimed to explore how young adults created meanings and actions of safety within their activism. Grounded Theory method was use to collect and analyze qualitative interviews with young adults often social change groups located in two medium-size cities inSweden. To interpret our findings, we drew upon interactionist concepts of shared definitions and joint action [Blumer, Herbert.1966. “Sociological Implications of the thought of George Herbert Mead.” American Journal of Sociology 71 (5): 535–544]. Shared definitions challenged narrow notions of unsafety by identifying uniform categories and harmful stereotypes as the source of the problem, and thereby locating constraints upon the capacity ofdifferent groups of young adults to define situations as (un)safe. Joint action combined an immediate response of moving to where young adults were with an enduring response of being there for young adults. Combined, these constituted an overarching social process of collective caring, which we linked to Isabel Lorey’s [2015. State of Insecurity. London: Verso] concept of practices of caring.
