FNS has historically estimated the participation rate of SNAP by using Census data and samples of SNAP administrative data, but modeling SNAP eligibility using survey data has a number of challenges. In response, FNS, the Economic Research Service, and the Census Bureau sought potential solutions to these issues by linking Census survey data with monthly administrative records at the person level.

FNS is committed to providing WIC participants with access to a variety of safe and healthy foods, including infant formula, and strongly encourages WIC state agencies to take expedient action to ensure that WIC participants can exchange recalled product on hand, and can use WIC benefits in their EBT balance or on paper WIC food instruments to purchase product that has not been recalled

This report, the latest in a series of annual reports on WIC eligibility, presents 2019 national and state estimates of the number of people eligible for WIC benefits and the percents of the eligible population and the US population covered by the program, including estimates by participant category. The report also provides estimates by region, state, U.S. territory and race and ethnicity.
