archives@tulane.edu / In response to extant literature on college students’ sense of belonging that analyzes the concept as a relatively siloed phenomenon, this study offers a mixed methods exploratory analysis of college students’ sense of belonging that examines multiple domains of college life simultaneously. Quantitative results reveal that students fall within three classes of sense of belonging – Low, Medium, High – and that sense of belonging to a campus organization is least impactful on the classes whereas sense of belonging to a friend group is most impactful. Key factors impact a students’ probability of being in a particular class of sense of belonging: Students from racial and ethnic minority backgrounds as well as non-Honors students are most likely to experience a low sense of belonging, and students from relatively high socioeconomic statuses are least likely to experience a low sense of belonging. Qualitative results analyze students’ definitions of sense of belonging and unpack aspects of the quantitative results. First, students’ definitions reveal four categories of sense of belonging: Self-Centrics, Co-Creators, Seekers, and Conformists. Second, campus organizations offer a framework by which students meet friends, and the importance of this structure goes largely unnoticed by students. On the contrary, students highlight the importance of sense of belonging to a friend group as instrumental to developing sense of belonging in other domains. Third, the theme of exclusion operates as a foil to the similarity that informs interviewees’ sense of belonging. Exclusion refers to perceptions that one is an insider or outsider, and a key component of exclusion is the degree to which students have agency in their experiences of exclusion. Fourth, Gateways of Belonging and Conduits of Belonging offer a means by which students strengthen sense of belonging in various domains. Gateways of Belonging refer to frameworks that bring together students around shared experience or purpose. Conduits of Belonging refer to specific roles that people fill in such a way that they model what sense of belonging can look like in a specific domain.
