This annual study helps the Food and Nutrition Service measure program performance of the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) and better understand the program’s reach and unmet nutrition assistance needs, particularly at state and participant levels.
Insight estimates WIC eligibility using the methodology recommended by the Committee on National Statistics of the National Research Council:
- National Estimates. Use data from the Current Population Survey’s Annual Social and Economic Supplement to create a national estimate of WIC-eligible infants and children and the average monthly number of WIC-eligible infants, children, and pregnant and postpartum women.
- State Estimates. Use data from the American Community Survey (ACS) data and each state’s share of the ACS-based estimates.
- Territorial Estimates. Use Puerto Rico Community Survey data to estimate WIC eligibility in Puerto Rico, and use Census Bureau International Database to estimate program eligibility in other U.S. territories.
