Resource | Research and Data | Payment Accuracy and Program Integrity The Extent of Trafficking in the SNAP: 2012–2014

Trafficking of Supplemental Nutrition Assistance Program benefits occurs when SNAP recipients sell their benefits for cash to food retailers, often at a discount. Although trafficking does not increase costs to the federal government, it is a diversion of program benefits from their intended purpose of helping low-income families access a nutritious diet. This report, the latest in a series of periodic analyses, provides estimates of the extent of trafficking during the period 2012 through 2014.

Resource | Research and Data The Reaching the Working Poor and Poor Elderly Study: What We Learned and Recommendations for Future Research

To increase its understanding of the reasons for nonparticipation, the Food and Nutrition Service(FNS) of the U.S. Department of Agriculture (USDA) contracted with Mathematica Policy Research, Inc. (MPR) to conduct a study of nonparticipation by low-income working and elderly households, entitled Reaching the Working Poor and Poor Elderly. This report summarizes what was learned and offers recommendations for how a national survey of the reasons for nonparticipation in the FSP should be designed and fielded.

Resource | Research and Data | Policy Analysis The Use of Food Stamps To Purchase Vitamin and Minerals Supplements

Interest, research, and expenditures on dietary supplements are growing very fast. Americans spent $8.2 billion in 1995 for vitamins, minerals, herbs and botanicals, and sports nutrition products. About half of all Americans reported at least some use of vitamins and minerals in response to recent surveys. The general goal of the study is to examine existing data that bear on a diverse set of pertinent issues.

Resource | Research and Data | Assessing/Improving Operations Feasibility Study of Capturing Food Data at Checkout

In the past, the Food and Nutrition Service (FNS) has relied on a series of large surveys to gather and compare information on food expenditures and food consumption among participants and non-participants to better understand the impacts of the Food Stamp Program (FSP) on the diet and nutritional status of program participants. Studies based on survey data, however, have a number of drawbacks, including the time and expense of collecting the survey data, sampling error, response bias, errors in respondent recall, and misinformation about what may have been purchased or consumed.

Resource | Research and Data | Assessing/Improving Operations Food Stamp Participants' Access to Food Retailers

In this report, data from the NFSPS are used to address several important questions concerning food store access of low-income households, including: (1) At what kinds of stores do low-income households shop? (2) What distances do low-income households travel to reach those stores? (3) What transportation methods do they use to reach their food stores? (4) Do low-income households engage in careful shopping behaviors that can allow them to get the most out of the money and food stamp benefits they spend on food? and (5) In general, how satisfied are low-income Americans with their shopping opportunities?

Resource | Research and Data | Assessing/Improving Operations Evaluation of the Expanded Off-Line EBT System in Ohio: Moving to a Statewide EBT System Using Smart Cards for Food Stamps

To explore the suitability of off-line electronic benefits transfer (EBT) as an alternative to paper issuance and on-line EBT issuance systems, USDA’s Food and Nutrition Service has supported the Ohio Department of Human Services in expanding off-line EBT issuance to all Food Stamp Program recipients in the state. A pilot project in Dayton, Ohio and a demonstration of a combined WIC-EBT off-line system in Wyoming have clearly established the technical feasibility of off-line EBT for FSP benefit issuance.

Resource | Research and Data | Payment Accuracy and Program Integrity Extent of Trafficking in Food Stamp Program

This study was the first in a series of studies that estimated the extent of retailer-level SNAP benefit trafficking. The major findings included large stores having only half the store violation rate that smaller stores had. Additionally, the overall benefit trafficking rate was 13.0% as compared to 1.3% in the latest trafficking rate study.
