A report by Lisa Mancino, Jessica E. Todd, and Benjamin Scharadin (January 2018).The Relationship Between Patronizing Direct-to-Consumer Outlets and a Household’s Demand for Fruits and Vegetables
This study uses data from USDA's National Household Food Acquisition and Purchase Survey (FoodAPS) to investigate whether patronizing farmers markets, roadside stands, and other direct-to-consumer (DTC) outlets increases a household’s spending for fruits and vegetables, including purchases at both DTC and non-direct food retailer. A report by Hayden Stewart and Diansheng Dong (January 2018).The Influence of Food Store Access on Grocery Shopping and Food Spending
Low access to foodstores (such as supermarkets) may mean that households rely on nearby retailers, like convenience stores or fast-food restaurants, that do not offer a variety of healthful foods. The report assesses how the local food environment, household mobility, and assets are related to where households shop for food. A report by Michele Ver Ploeg, Elizabeth Larimore, and Parke E. Wilde (October 2017).The Food-Spending Patterns of Households Participating in the Supplemental Nutrition Assistance Program: Findings From USDA's FoodAPS
This study uses data from USDA's National Household Food Acquisition and Purchase Survey (FoodAPS) to compare food expenditures of SNAP households with those of eligible nonparticipant households and all households. The researchers examined variations in food spending by SNAP households' characteristics, the contribution of SNAP benefits to household food expenditures, and changes in food-spending patterns during the month after receiving benefits. A report by Laura Tiehen, Constance Newman, and John A. Kirlin (August 2017).
Using data from USDA’s 2012 National Household Food Acquisition and Purchase Survey (FoodAPS), this study examines characteristics of households with and without obese children to understand potential reasons behind the dissimilar risks of child obesity. A report by Young Jo (September 2017).Food-at-Home Expenditures: Comparing Commercial Household Scanner Data From IRI and Government Survey Data
This ERS report compares proprietary household scanner data to nationally representative Federal Government survey data and finds that reported household food-at-home expenditures in commercial scanner data were lower than in two Federal Government surveys. The report details the comparison methodology and describes implications for using the commercial data in food economics research. A report by Megan Sweitzer, Derick Brown, Shawn Karns, Mary K. Muth, Peter Siegel, and Chen Zhen (September 2017).
Data from USDA's National Household Food Acquisition and Purchase Survey (FoodAPS), the first nationally representative household survey to collect data on foods purchased or acquired during a survey week, are compared with data from other national-level, food-related surveys.

(July 2016).Where Households Get Food in a Typical Week: Findings from USDA’s FoodAPS
Understanding where U.S. households acquire food, what they acquire, and what they pay is essential to identifying which food and nutrition policies might improve diet quality. This report uses USDA’s National Household Food Acquisition and Purchase Survey (FoodAPS) to study where households acquired food during a 7-day period in 2012. A report by Jessica E. Todd and Benjamin Scharadin (July 2016).WIC Household Food Purchases Using WIC Benefits or Paying Out of Pocket: A Case Study of Cold Cereal Purchases
WIC households incur no cost for WIC-approved foods, and economic theory suggests that they may be less sensitive to prices when using WIC benefits than when paying out of pocket. ERS examines this assumption in a case study of WIC households' choices in purchasing cold cereals. A report by Diansheng Dong, Hayden Stewart, Elizabeth Frazão, Andrea Carlson, and Jeffrey Hyman (May 2016).Where Do Americans Usually Shop for Food and How Do They Travel To Get There? Initial Findings from the National Household Food Acquisition and Purchase Survey
This report compares food shopping patterns of (1) Supplemental Nutrition Assistance Program (SNAP) households to nonparticipant households, (2) participants in the Special Supplemental Nutrition Assistance Program for Women Infants and Children (WIC) to nonparticipants, and (3) food-insecure to food-secure households. A report by Michele Ver Ploeg, Lisa Mancino, Jessica E. Todd, Dawn Marie Clay, and Benjamin Scharadin (March 2015).

The USDA, Economic Research Service and the University of Maryland, College Park hosted the "International Food Acquisition Research and Methods" (iFARM) workshop on October 20–21, 2022 at the University of Maryland. The goal of the workshop was to bring together researchers from different disciplines to discuss advancements in methods for collecting and processing food acquisition data. Conference proceedings can be found on the University of Maryland’s Social Data Science Center’s iFARM webpage.
The National Bureau of Economic Research (NBER), with support from USDA's Economic Research Service and the Food and Nutrition Service (FNS), organized a 2-year research initiative consisting of 10 distinct projects that leveraged the FoodAPS data to address issues related to food security, nutrition, and health in the United States. The funding for the NBER grants ran from fiscal year 2016 through fiscal year 2018. Information and outcomes from the grants can be found on the NBER FoodAPS page.
The University of Kentucky Center for Poverty Research, in cooperation with ERS, competitively awarded grants to qualified individuals and institutions to provide rigorous research that utilized FoodAPS to expand our understanding of household food behaviors and the Supplemental Nutrition Assistance Program (SNAP). Research issues of interest included: benefit adequacy, diet quality, cost of a healthy diet, food security, and the role of the local food environment and other geographic factors. In addition to the FoodAPS data, geographically-linked data on the local food environment and food prices compiled as part of the FoodAPS Geography Component (FoodAPS-GC) were available for awardees. Three grants were awarded for 2016, and 12 grants were awarded in 2014.
In 2014, 12 grants were awarded across two topical domains: (1) Household food behaviors and the Supplemental Nutrition Assistance Program (SNAP) program—including the issues of benefit adequacy, diet quality, cost of a healthy diet, and food security, and (2) the role of the local food environment and other geographic factors on household food purchase and acquisition decisions. The final reports are available as 2016 discussion papers.
