Stevens Institute of Technology hosts chapters of fifteen social and academic fraternities and sororities, many of which were founded on campus over a century ago. These groups, through their social, academic, leadership and alumni networking programs, are aimed at building lifelong connections among participants and to the institute. Indeed, they are successful at this aim, as evidenced by the fact that across the nation, "most of the donations made to alma mater are given by members of Greek organizations." Popular hubs of social activity, in 2013, 25% of Stevens Institute students were members of these organizations.
