This study’s aim is to determine effects of policy variables on enrollment in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) using a framework for the study of access. Secondary analysis of 1994 data from public documents and agencies for the 50 states was conducted. Independent variables were ratio of the federal WIC grant to the eligible population, state supplementation of WIC, administrative and food dollars per person, WIC population per clinic, and WIC priority categories served. The dependent variable was the eligible WIC population enrolled. State supplementation of the WIC budget, administrative and food dollars per person, cost of living, population density, population distribution, and ratio of the federal WIC grant to the eligible population accounted for 85% of variance in WIC enrollment. Policy recommendations include reorienting the federal funding formula toward incentives for enrollment, state supplementation of WIC, and examination of administrative and food costs.
