    The goal of federal food and nutrition programs in the United States is to improve the nutritional well-being and health of low income families. A large body of literature evaluates the extent to which the Supplemental Program for Women Infants and Children (WIC) has accomplished this goal, but most studies have been based on research designs that compare program participants to non-participants. If selection into these programs is non-random then such comparisons will lead to biased estimates of the program’s true effects. In this study we use the rollout of the WIC program across counties to estimate the impact of the program on infant health. We find that the implementation of WIC lead to an increase in average birthweight and a decrease in the fraction of births that are classified as low birthweight. We find no evidence that these estimates are driven by changes in fertility. Back-of-the-envelope calculations suggest that the initiation of WIC lead to a ten percent increase in the birthweight of infants born to participating mothers. (author abstract)

    The Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) provides low-income pregnant women, postpartum mothers, infants, and children up to age 5 with select foods, nutrition education, and health care and government service referrals. WIC aims to improve the health of participants and prevent later health problems. This brief summarizes key features of the WIC program, including eligibility rules, participation, benefits, and administration. It presents the 2009 estimates of WIC eligibility and coverage for the nation and the states. Also summarized are recent improvements in WIC administrative practices and nutrition outcomes.

    WIC participation among eligible children is significantly lower than participation among infants. This paper explores possible explanations for the decline in participation including the need for recertification and changes in family composition. Discrete time hazard rate models are used to study the timing of exit from the WIC program for children who participate as infants. The models are estimated using the 2004 Survey of Income and Program Participation. The results suggest that the risk of exit from the WIC program is higher in recertification months than other months and for families with more children in the age range for WIC eligibility. Additionally, comparisons to results obtained from the 2001 SIPP suggest that changes in the interviewing methodology introduced in the 2004 SIPP reduced the magnitude of seam bias in WIC spells.

    The Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) provides food, nutrition education, breastfeeding support, and health care and social service referrals to nutritionally at-risk low-income pregnant women, new mothers, infants, and children through age 4. This report offers updated estimates of the population that met these criteria and was eligible for WIC benefits in each of the years 1994 through 2007. These revise a set of estimates published by the USDA Food and Nutrition Service (FNS) in 2006. The new series builds on the methodology recommended by the Committee on National Statistics of the National Research Council (CNSTAT) and more accurately captures changes in the breastfeeding practice of new mothers during their period of WIC eligibility. In 2007, 14.2 million individuals were eligible for WIC benefits in an average month. The program served 8.4 million, or 59 percent of those eligible. (author abstract)
