The National Survey of WIC Participants (NSWP) study series is designed to describe state and local agency characteristics, examine participants’ characteristics, assess participants’ experiences with WIC, and estimate improper payments resulting from certification errors in WIC. The study is conducted approximately every 10 years, and the current study is the third iteration (NSWP-III) in the series.
This study primarily uses 2011–2016 National Health and Nutrition Examination Survey (NHANES) data to examine bivariate relationships between reported WIC participation and outcomes including diet quality, indicators of nutrition and health, food consumption patterns, and nutrient intakes among 1- to 4-year-old children. Most results presented in this report are unadjusted and descriptive only, and do not infer causality. They are intended to contribute to the evidence base needed to inform future research and, subsequently, WIC policy and practice.
This report supplements FNS administrative data on total food costs by estimating the average monthly food costs for each WIC participant category and food package type. It also estimates total pre- and post-rebate dollars spent on 18 major categories of WIC-eligible foods in FY 2018.
