Whilst most social and educational research on friendship focuses on children at school, it remains a crucially important factor for students in higher educationand can play a key role in the maintenance, exacerbation or subversion of dominant forms of social inequalities. This paper explores the complexities of such dynamics in relation to friendship and social life at university, utilizing data from an in-depth qualitative study of HE students at a UK campus university. Students stressed the importance of friendship for comfort and a sense of 'belonging'. Nevertheless, students describe the continuation of cliques, hierarchies and exclusions that are more commonly linked to sociality at school, and patterns of differential experience can be discerned between groups that arguably work to perpetuate disadvantage, particularly in relation to students living off-campus, who are more likely to come from minority ethnic groups and/or working-class backgrounds. We argue that despite the conception that friendship is an individual, personal experience, it is very much influenced by social positionings such as gender, class, age, and ethnicityand in patterns that may have significant repercussions for students in relation to happiness and wellbeing at university.
