The Special Supplemental Nutrition Program for Women, Infants and Children (WIC) provides supplemental nutritious foods, nutrition education, and referrals to other health, welfare, and social services. WIC eligibility is restricted to infants, children age 1 through 4, and pregnant and postpartum women with low incomes. This project uses 2010 Census data to estimate WIC eligibility for the nation, states, the District of Columbia, and territories. In 2010, 14.6 million individuals were eligible for WIC benefits in an average month, including 63.8 percent of all infants born. The share of individuals eligible for benefits that participates in WIC ranges widely across the states.
