Food insecurity is widespread among college students in the United States. CalFresh food benefits, known federally as the Supplemental Nutrition Assistance Program, or SNAP, can help students in California pay for food, but may not reach all eligible students. CalFresh enrollment rates among students have been difficult to estimate due to incomplete data on California students' eligibility for and enrollment in the CalFresh program.1 To overcome these issues, the California Policy Lab (CPL) partnered with the California Community College system (CCC), the University of California Office of the President (UCOP), the California Department of Social Services (CDSS), and the California Student Aid Commission (CSAC) to build a linked database of student-level administrative data on college enrollment, financial aid, and CalFresh participation.
