Resource | Research and Data | Food Security Trends in USDA SNAP Participation Rates: Fiscal Years 2016 to 2020

This report is the latest in a series on Supplemental Nutrition Assistance Program (SNAP) participation rates, which estimate the proportion of people eligible for benefits under federal income and asset rules to those who actually participate in the program. Because the coronavirus COVID-19 public health emergency affected data collection starting in March 2020, this summary covers only the pre-pandemic period of October 2019 through February 2020.

Resource | Research and Data | Participation Rates Reaching Those in Need: State SNAP Participation Rates in 2009

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.

Resource | Research and Data | Payment Accuracy and Program Integrity The Extent of Trafficking in SNAP: 2006–2008

This is the fifth report in a series of periodic analyses to estimate the extent of trafficking in the Supplemental Nutrition Assistance Program (SNAP). Trafficking – selling SNAP benefits to food retailers for cash - impedes the mission and compromises the integrity of SNAP. While not a cost to the Federal Government, trafficking diverts benefits from their intended purpose of helping low-income families access a nutritious diet. The Food and Nutrition Service (FNS) aggressively acts to control trafficking by using SNAP purchase data to identify suspicious transaction patterns, conducting undercover investigations, and collaborating with other investigative agencies.

Resource | Research and Data | Participation Rates Reaching Those in Need: State Food Stamp Participation Rates in 2003

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.

Resource | Research and Data The Effects of Simplified Reporting on Food Stamp Payment Accuracy

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.

Resource | Research and Data | Assessing/Improving Operations Evaluation of Food Stamp Research Grants To Improve Access Through New Technology and Partnerships

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.

Resource | Research and Data | Food Security Impact of Food Stamp Payment Errors on Household Purchasing Power

Most discussion of payment accuracy in the Food Stamp Program focuses on the overall level and cost of payment errors. Rarely does the discussion focus on the impact of payment errors on individual households affected. This analysis – based on 2003 food stamp quality control data – leads to two broad conclusions. First, virtually all households receiving food stamps are eligible. Thus, the problem of erroneous payments is not so much one of determining eligibility, but rather one of attempting to finely target benefits to the complicated and changing circumstances of low-income households. Second, most overpayments to eligible households are small relative to household income and official poverty standards. As a result, most food stamp households are poor, and they remain poor even when overpaid.
