The WIC Nutrition Services and Administration cost study examines how program funds are expended by state and local agencies to support the management and operation of WIC. The study analyzed data from a national survey of state and local agencies, cases studies, and FY 2013 WIC administrative data.

This report, the latest in a series of annual reports on WIC eligibility, presents 2014 national and state estimates of the number of people eligible for WIC benefits and the percent of the eligible population covered by the program, including estimates by participant category.

This report explores WIC state agencies’ ability to collect, store, retrieve, and report data to meet policy and program management needs now and in the future.

The purpose of this study is to evaluate the effectiveness of state agencies current peer group systems, and to provide guidance to state agencies on how to evaluate and update their systems. Specifically, it uses empirical analysis to identify one or more effective models for establishing vendor peer groups that could apply to most state agencies.

The WIC Infant and Toddler Feeding Practices Study 2/“Feeding My Baby” Study captures data on WIC caregivers and their children over the first 5 years of each child’s life to address a series of research questions regarding feeding practices, the effect of WIC services on those practices, and the health and nutrition outcomes of children on WIC.

The National Academies of Sciences, Engineering, and Medicine  convened an expert committee to review and assess the nutritional status and food and nutritional needs of the WIC-eligible population and provide recommendations based on its review and grounded in the most recently available science. The committee produced three reports as part of this task. 

The WIC Participant and Program Characteristics (PC 2006) report summarizes demographic characteristics of WIC participants nationwide in April 2006, along with information on participant income and nutrition risk characteristics. A national estimate of breastfeeding initiation for WIC infants is included. The report also describes WIC members of migrant farm-worker families.

To assist nutrition educators in their use of relevant research, FNS conducted a review of studies on: Message framing, Use of interactive technology to tailor messages, and Intervention intensity. The review was intended to document how these specific features of nutrition messages and interventions influence the likelihood of promoting more healthful food choices.

The tables in this report summarize the asset and vehicle holdings of five low-income household groups by their food stamp asset and income eligibility status in September 2002.

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.
