This report describes the characteristics of SNAP households and participants nationwide in fiscal year 2011 (October 2010 through September 2011). It also presents an overview of SNAP eligibility requirements and benefit levels in fiscal year 2011.

As the time for reauthorization of SNAP again approaches, it is useful to take stock of its accomplishments, identify those features that have contributed to its success, and look for new opportunities to strengthen operations to achieve program goals more fully. To that end, this is a summary of past research on program operations and outcomes.

This report, the first of three, addresses the first objective of the study, which is to explore the characteristics and experiences of WIC participants.

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.
