Supplemental Nutrition Assistance Program: Examining the Evidence to Define Benefit Adequacy

The purpose of this study was to examine how to define “adequacy” of SNAP allotments objectively in the context of program goals to improve food security and access to a healthy diet, existing data sources that could inform an assessment of the adequacy of existing and potential alternative SNAP allotments, and new data requirements to strengthen the evidence-base and allow for further rigorous analyses.  It examined whether it is feasible to objectively define “adequacy”, and to determine what data and analysis were needed to create an evidence based assessment of “adequacy”.
