College students who are parents or caregivers of dependent children make up more than one in five U.S. undergraduates. Colleges need basic information about the experiences and outcomes of the student parents they serve, since these students face distinct challenges, including high rates of economic insecurity and significant time and caregiving demands that can affect their educational outcomes (Institute for Women's Policy Research and Ascend at the Aspen Institute 2019). This briefing paper discusses why data on student parents are critical to increasing equity in college outcomes, and reviews existing and potential new data sources on undergraduate college students with children. It also provides recommendations for improving data collection efforts around parent status, including examples of how these data can be collected by institutions of higher education.
