Food insecurity is widespread among college students in the United States. CalFresh food benefits, known federally as the Supplemental Nutrition Assistance Program (SNAP) can help students in California pay for food, but may not reach all eligible students. To better measure student participation in CalFresh, the California Policy Lab (CPL) partners 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). Through this partnership, CPL has created a linked database of student-level administrative data on college enrollment, financial aid, and CalFresh participation that makes this analysis possible. This data point provides estimates of CalFresh participation rates among community college and University of California (UC) students in California. In the academic year 2021-22 (June 2021-May 2022), the second year of the COVID-19 pandemic, 10.7% of CCC students, 14.8% of UC undergraduate students, and 8.6% of UC graduate students participated in CalFresh. The overall CCC student population continued to decline in 2021-22, while the overall UC undergraduate and graduate populations increased. The share of CCC students participating in CalFresh remained largely the same while participation among UC students continued to trend upward.
