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 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 2009 and in the two previous fiscal years. This report also presents estimates of state participation rates for eligible “working poor” individuals over the same period. Although SNAP provides an important support for working families, the working poor have participated at rates that are substantially below those for all eligible persons. 

This report describes individuals’ patterns of participation in the SNAP from 2004 to 2006, a period of caseload growth and improving economic conditions. Based on data from the U.S. Census Bureau’s Survey of Income and Program Participation, the study explores reasons that individuals enter and leave SNAP, how long they receive SNAP benefits, and whether they return to the program after exiting. The report also examines whether participation patterns in the mid-2000s changed from earlier periods.

This study analyzes which factors are associated with individuals’ decisions to start participating in the SNAP and with decisions to leave the program during the period 2004 to 2006. Based on data from the U.S. Census Bureau’s Survey of Income and Program Participation, the study uses a technique called “multivariate regression” to isolate the impact of various factors associated with participation decisions while holding other factors constant.

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.

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 2008 and in the two previous fiscal years.

Because of ethical and legal considerations, FNS cannot examine the effect of participation in SNAP on outcomes such as food security through experimental studies that would require withholding benefits from those eligible. Therefore, this study was conducted to identify whether regression modeling of extant data could yield adequate comparison groups to assess SNAP outcomes.

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 2007 and in the two 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.
