WIC#

The Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) provides vouchers for food and formula to low-income mothers and children deemed to be at nutritional risk. The Food and Nutrition Service (FNS), a division of the United States Department of Agriculture (USDA), administers WIC.

Examples#

How WIC values depend on income#

Consider a pregnant woman in Oregon whose husband has no income, and whom a WIC office has deemed to be at nutritional risk.
