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. 

The Summer Meals Study provides a comprehensive, nationally representative assessment of the two summer meal programs operated by USDA: the Summer Food Service Program and the National School Lunch Program Seamless Summer Option. It is the first national study to simultaneously examine the facilitators and barriers to program participation among participating and nonparticipating families, sponsors, and sites. This study examines the characteristics of participating and nonparticipating children, including sociodemographic characteristics, household food security status, reasons for participation or nonparticipation, and satisfaction with the meals served to children in the summer of 2018.
