WIC is funded by an appropriation from Congress to the United States Department of Agriculture (USDA). The USDA allocates monies to the various States and Territories (American Samoa, Guam, Puerto Rico and the US Virgin Islands) Health Departments. Various local WIC agencies receive funds based on the number of WIC participants they serve.
WIC is also funded, in part, by private industry. WIC generates revenue through competitive bidding on some of the foods the WIC program provides. This is inclusive of a rebate.
