The Special Supplemental Nutrition Program for Women, Infants, and Children, commonly known as the WIC program, serves to safeguard the health of low-income women, infants, and children younger than 5 who are at nutritional risk. As the third largest food and nutrition assistance program, WIC served about 6.9 million participants per month in fiscal year 2018, including almost half of all infants born in the United States. Federal program costs for WIC totaled $5.3 billion in fiscal year 2018.
ERS conducts and funds studies and evaluations of the WIC program and other USDA domestic food and nutrition assistance programs. WIC provides supplemental food, nutrition education, and referrals to health care and other social services to low-income, nutritionally at-risk women, infants, and children up to 5 years of age. A key report explains how the WIC program works, examines program trends, describes some of the lesser-known effects of WIC, and discusses some of the major economic issues facing the program. See:The WIC Program: Background, Trends, and Economic Issues, 2015 Edition
Breastfeeding rates among WIC participants are lower than the U.S. average. In a recent report requested by Congress, ERS estimated the effects that a hypothetical increase in breastfeeding rates in WIC would have on the number of WIC participants, costs to WIC and Medicaid, and health-related costs that accrue to WIC households or their health insurance providers.

Information about program eligibility requirements, benefits, and application process is available from USDA's Food and Nutrition Service, the agency that administers the WIC program.
ERS has compiled a database of over 1,100 peer-reviewed research reports and articles covering a broad spectrum of food and nutrition assistance research based on both intramural and extramural research published at ERS and elsewhere. The database is searchable by title, lead author, topics such as WIC, year of publication, data set analyzed and exact word(s) or phrases contained in the publication’s bibliographic citation.
