This report – the latest in an annual series – presents estimates of the percentage of eligible persons, by state, who participated in SNAP during an average month in FY 2010 and in the 2 previous fiscal years. This report also presents estimates of state participation rates for eligible “working poor” individuals (persons in households with earnings) over the same period. Although SNAP provides an important support for working families, the working poor has participated at rates that are substantially below those for all eligible persons.

This report is the latest in a series on SNAP participation rates. Estimates are based on the March 2011 Current Population Survey and program administrative data for fiscal year 2010. The findings represent participation rates for FY 2010.

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 pamphlet provides estimates for Food Stamp Program participation rates by states. It will be the first widely-released document showing the percentage of eligible people, by state, who actually participate in the program. Because the data are from January 1994, prior to the enactment of the Personal Responsibility and Work Opportunity Reconciliation Act of 1996, they provide baseline data on participation rates prior to the enactment of welfare reform.

This report provides a comprehensive picture of individuals’ patterns of participation in the Food Stamp Program during the early 1990s, a period of rapid caseload growth. Based on data from the 1990 and 1991 SIPP panels (national longitudinal surveys covering the period from late 1989 to early 1994), the research addresses questions about why individuals enter and leave the FSP, how long participants stay on the program, whether individuals return at a later time and what factors distinguish those who are more dependent on the program from those who are less dependent.
