Resource | Research and Data | Payment Accuracy and Program Integrity 2005 WIC Vendor Management Study

In 1991 and 1998, FNS conducted national studies of WIC vendors to determine the extent of vendor violation of program rules. After the 1998 study, FNS issued regulations to correct vendor practices. The 2005 study replicates the 1998 study to determine whether the regulations were effective, and to measure the frequency of vendor violations and the degree to which vendors charge accurate prices for WIC transactions.

Resource | Research and Data | Participation Rates WIC Program Coverage: How Many Eligible Individuals Participated 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.
