【 摘 要 】

USDA’s Economic Research Service (ERS) has purchased proprietary retail scanner data (InfoScan) since 2008 to examine food policy questions. To determine how representative the data are, this report compares the number of stores and sales revenue reported in the InfoScan data with the same information from other datasets.
