Those from low socioeconomic status (SES) often lack access to public space and, when they have access, they are often discouraged from using public space. Scholars from human geography and related fields have argued that this limits engagement in civic life and undermines sense of belonging in one’s community. In the present work, we consider whether lower-SES students face this predicament in higher education, particularly at elite public institutions. Across four studies, we find that, compared with higher-SES students, lower-SES students use public space on campus less—iconic public space in particular—and this can mediate the relationship between SES and sense of belonging at the University. We also find that experimentally increasing students’ use of public space can reduce and even close SES gaps in felt belonging. Taken together, the present studies suggest that use of public space matters for belonging and for understanding gaps in belonging. This work contributes to our understanding of SES disparities in higher education. More generally, it illustrates the importance of public space.
