The U.S. Department of Agriculture’s (USDA) National Household Food Acquisition and Purchase Survey (FoodAPS) is the first nationally representative household survey to collect data on foods purchased or acquired during a survey week, producing results that are both nationally representative and representative of Supplemental Nutrition Assistance Program (SNAP) participants as well as of low-income non-SNAP households. In order to assess the quality of FoodAPS data, this report compares estimates from FoodAPS to estimates from other national-level food-related surveys, examining: (1) general demographic and socio-economic characteristics; (2) food expenditures; (3) food security; (4) SNAP participation and income; and (5) diet behavior and health. FoodAPS estimates of total, food-at-home (FAH) spending are greater than estimates from the Consumer Expenditure Survey (CE) but less than those from the National Health and Nutrition Examination Survey (NHANES). Compared to other national-level surveys, FoodAPS estimates a greater share of households with low or very low food security.
