Resource | Research | Participation Rates WIC Program Coverage: How Many Eligible Individuals Participated in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC): 1994 to 2003?

Recently, the method used to calculate the number of individuals eligible for the WIC program was evaluated and an improved methodology was developed. These new, improved estimates provide better insight on the WIC program and should help improve the program in the future. The new estimates show that 13.5 million individuals were eligible for WIC and 7.7 million participated in WIC in 2003. This coverage rate of 57% is consistent with trends since 2000 and is similar to the coverage rate found in the Food Stamp Program.
