FNS Documents & Resources

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 provides information about the demographic and economic circumstances of SNAP households in fiscal year 2008. 

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. 

This report is the latest in a series on SNAP participation rates. Estimates are based on the March 2008 Current Population Survey and program administrative data for FY 2007. 

To explore other options for assessing impacts, FNS awarded a contract to provide FNS with new information on: experiences and satisfaction of participants in FNS programs, and impacts of program participation on food security, diet quality, and other indicators of household well-being.

This report is the latest in a series of publications presenting estimates of the percentage of eligible persons, by state, who participate in the Food Stamp Program. The participation rate – a ratio of the number of participants to the number of people eligible for benefits – is an important measure of program performance. 

FNS and other researchers have used a variety of approaches to calculate food stamp participation rates. While different approaches can look similar in concept, the results – for particular states or for the nation as a whole – can often look quite different. These differences can be confusing for users who seek to describe the success of the Food Stamp Program without becoming experts in statistics and data analysis. This paper provides an overview and comparison of two sets of estimates produced by FNS as indicators of Food Stamp Program performance.

Using Food Stamp Quality Control data from fiscal year 2000, this analysis suggests that the simplified reporting policies adopted by states in 2004 could have lowered error rates by 1.2 to 1.5 percentage points.

Low participation rates among low-income people eligible for food stamp benefits have prompted a number of outreach and public education efforts. In 2002, the Food and Nutrition Service awarded $5 million in grants to community-based organizations in 15 States to investigate how to increase participation among people eligible for food stamp benefits. The evaluation of these grants describes the features and outcomes of these 18 projects.
