The rapid proliferation and ongoing transformation of digital technologies and social media platforms have had a substantial influence on the participatory cultures of young people and their associated social connections. This social/digital nexus raises important questions of social cohesion, with digital technologies at once augmenting social interaction whilst simultaneously creating an uneven landscape of access for participation. To address this interface of the digital and the social, this paper presents a qualitative study of 24 tertiary students from ethnic minority backgrounds living in Auckland, New Zealand, who use social media. Incorporating a pre-screening questionnaire, a one-week social media diary and semi-structured interviews, this study presents the ways in which digital belongings influence participants' practices of friendship and family. The ways that connective media influence, and even constrain interaction alongside the politics of belongings, are theorised to further examine the meanings and experiences behind participants' social media usage and social contact. By integrating these ideas, this paper presents the ways in which young university students use social media and the extent to which digital interaction and networking influence social participation and social cohesion.
