The Supplemental Nutrition Assistance Program, Special Supplemental Nutrition Program for Women, Infants, and Children, National School Lunch Program, and School Breakfast Program are complementary, serving different nutritional needs of low‐income children. We analyze determinants of the number of nutrition assistance programs low‐income households with children participate in given multiprogram eligibility. Results obtained using Survey of Income and Program Participation data indicate households with young children, in metro areas, and with a college‐educated or married respondent participate in fewer programs given eligibility. Program factors that reduce participation stigma and transaction costs are further associated with increased take‐up.
