This study uses calendar year 2011 point-of-sale transaction data from a leading grocery retailer to examine the food choices of SNAP and non-SNAP households . On average, each month's transaction data contained over 1 billion records of food items bought by 26.5 million households in 127 million unique transactions.

This study examined the feasibility of creating a data collection system capable of directly and automatically providing USDA with item-level data on purchases made by SNAP households. Data would be captured at the point of sale from purchases made using EBT cards.

This analysis explores patterns of permanent benefit removal in Texas, Arizona, and Wisconsin, three states where EBT is the primary method of benefit distribution, but where there are low percentages of elderly. The findings suggest that a relatively small number of food stamp participants do not access their benefits for extended periods.
