The 1996 study of WIC program and participant characteristics, like PC92 and PC94, is substantially different from earlier efforts to collect data on WIC participants. PC96 employs the prototype reporting system which was developed by FNS for the collection of participant information from state WIC agencies.

This publication is based on the WIC Infant Feeding Practices Study (WIC-IFPS) sponsored by FNS. The WIC-IFPS is a one-year longitudinal study, which describes the infant feeding practices over the first year of life among a nationally representative sample of approximately 900 mothers who participated in WIC while they were pregnant.
