Data & Research
This report provides improper payment estimates for FY 2010 using a methodology for “aging” the 2005 bookend study. The methodology yields nationally representative estimates of the number of vendors that over- and undercharged and the amount of over- and undercharges across all WIC vendors.
This report provides improper payments estimates for FY 2009 using a methodology for “aging” the 2005 bookend study. This updates previous reports providing estimates from 2005 to 2008.
These demonstration projects are being conducted under the authority and funding provided by the Agriculture, Rural Development, Food and Drug Administration, and Related Agencies Appropriations Act of 2010. The Appropriations Act authorized the Secretary of Agriculture to use $85 million to develop and test alternative methods of providing access to food for low-income children in urban and rural areas during the summer months, when schools are not in regular session.
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.
The Prime Vendor Pilot was conducted as part of USDA's Business Process Re-engineering efforts to improve the administration and operation of the Food Distribution Program on Indian Reservations. Under this pilot, USDA partnered with the Department of Defense, which had an existing contract with commercial vendors and distributors.
FNS published “The WIC Vendor Management Study, 1998” in July 2001 which examined, in part, the extent to which retail grocers, defined as WIC “vendors” were violating program rules and regulations. The 1998 study is a follow-up to the “WIC Vendor Issues Study, 1991” published by FNS in May 1993.
This report fulfills the request from Congress in the House Appropriations Committee Report (HR 107-116), which accompanied the Agriculture Appropriations Act for fiscal year 2002.
The purpose of the study was to learn the extent to which retail grocers, defined as "vendors" in the WIC Program, authorized to provide food to WIC participants, were violating program rules and procedures, and to determine which programmatic and/or demographic variables could be associated with vendor violations.
In the past, the Food and Nutrition Service (FNS) has relied on a series of large surveys to gather and compare information on food expenditures and food consumption among participants and non-participants to better understand the impacts of the Food Stamp Program (FSP) on the diet and nutritional status of program participants. Studies based on survey data, however, have a number of drawbacks, including the time and expense of collecting the survey data, sampling error, response bias, errors in respondent recall, and misinformation about what may have been purchased or consumed.
