Note: Because of the COVID-19 pandemic, the 2020 PRCS was not released. The 2020 estimates for Puerto Rico use the 2019 PRCS. WIC participation and eligibility data for Indian Tribal Organizations (ITO) are included in the data for the State where the ITO is located.
Definitions: "Total population" refers to the total number of infants, young children (aged 1–4), pregnant women, and postpartum breastfeeding and non-breastfeeding women in the selected state. State-level estimates are subject to greater statistical uncertainty than national-level estimates, and some apparent year-to-year changes may be entirely the result of sampling variability, especially in smaller states.
