The WIC Participant and Program Characteristics (PC 2004) report summarizes demographic characteristics of WIC participants nationwide in April 2004, along with information on participant income and nutrition risk characteristics. A national estimate of breastfeeding initiation for WIC infants is included. The report also describes WIC members of migrant farm-worker families.

Since 1992, FNS has produced biennial reports on WIC participant and program characteristics based on the WIC Minimum Data Set compiled from state management information systems. The 20 items included in the MDS are collected as part of ongoing WIC operations and consist primarily of in formation related to participant eligibility.

This study was designed to describe the characteristics of adolescent women in WIC, as well as to identify their special needs, such as nutrition education, referral to other agencies, and their satisfaction with the services they received. The Adolescent WIC Participants Study was the first national survey of pregnant teenagers and mothers served by the WIC program.
