The WIC Participant and Program Characteristics (PC 2006) report summarizes demographic characteristics of WIC participants nationwide in April 2006, 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.

The report draws on data for households participating in the Food Stamp Program under normal rules and thus does not include information about those who received disaster assistance after the Gulf Coast hurricanes in September and October 2005. 

The tables in this report summarize the asset and vehicle holdings of five low-income household groups by their food stamp asset and income eligibility status in September 2002.

The School Lunch Eligible Non-Participants Study, conducted for USDA's Food and Nutrition Service, was designed to determine "why children eligible to participate for free and reduced-price meals do not apply or participate" in school nutrition programs.

The 1994 study of WIC program and participant characteristics (PC94), like the 1992 study (PC92), is substantially different from earlier efforts to collect data on WIC participants. PC94 employs the prototype reporting system which was developed by FNS for the 1992 study and which routinizes the collection of participant information from state WIC agencies.
