The Nutrition Assistance Program in the Commonwealth of Puerto Rico provides a monthly benefit for food to low-income households that includes both cash and noncash portions. Three-fourths (75 percent) of the benefit must be redeemed for eligible food items through electronic benefit transfer (EBT) at certified retailers. The remaining 25 percent may be redeemed in cash. The entire benefit (both the noncash and cash portions) is to be used only for the purchase of eligible food items.

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.
