The Food-Spending Patterns of Households Participating in the Supplemental Nutrition Assistance Program: Findings From USDA's FoodAPS A report by Laura Tiehen, Constance Newman, and John A. Kirlin, ERS. 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 (August 2017).
A report by Young Jo, ERS. 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 (September 2017).
Comparing National Food Acquisition and Purchase Survey (FoodAPS) Data With Other National Food Surveys’ Data

A report by Dawn Marie Clay, Michele Ver Ploeg, Alisha Coleman-Jensen, Howard Elitzak, Christian Gregory, David Levin, Constance Newman, and Matthew P. Rabbitt, ERS. 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

A report by Jessica E. Todd and Benjamin Scharadin, ERS. 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 (July 2016).

WIC Household Food Purchases Using WIC Benefits or Paying Out of Pocket: A Case Study of Cold Cereal Purchases

A report by Diansheng Dong, Hayden Stewart, Elizabeth Frazão, Andrea Carlson, and Jeffrey Hyman, ERS. 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 (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

A report by Michele Ver Ploeg, Lisa Mancino, Jessica E. Todd, Dawn Marie Clay, and Benjamin Scharadin, ERS. 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. On March 31, 2015, ERS hosted a webinar: First Findings from USDA's FoodAPS that provided an overview of FoodAPS and this report.

Published reports and articles based on FoodAPS data are also searchable in the ERS Food and Nutrition Assistance Research Reports Database.

"Discrete Choice Model of Food Store Trips Using National Household Food Acquisition and Purchase Survey (FoodAPS)"by Amy Hillier, Tony E. Smith, Eliza D. Whiteman, and Benjamin W. Chrisinger, International Journal of Environmental Research and Public Health, 14: 1133. This article analyzed data from the National Household Food Acquisition and Purchase Survey (FoodAPS), using a conditional logit model to determine where participants shop for food at home and how individual and household characteristics of food shoppers interact with store characteristics and distance from home in determining store choice. Overall, participants were more likely to choose larger stores, conventional supermarkets rather than super-centers and other types of stores, and stores closer to home. Interaction effects show that participants receiving Supplemental Nutrition Assistance Program (SNAP) were even more likely to choose larger stores. This study demonstrates the value of explicitly spatial discrete choice models and provides evidence of national trends consistent with previous smaller, local studies (September 2017).

"The Association Between Consumer Competency and Supplemental Nutrition Assistance Program Participation on Food Insecurity"by Yunhee Chang, Jinhee Kim, and Swarn Chatterjee, Journal of Nutrition Education and Behavior, 2017, 49(8): 657-666. This article examines whether Supplemental Nutrition Assistance Program (SNAP) participants exhibited lower food insecurity when they also demonstrated desirable behaviors in the areas of financial management, nutrition literacy, and conscientious food shopping. Using data from FoodAPS, this study examined whether consumer competency is a factor that affects food insecurity. Consumer competency-related factors such as financial management ability, not defaulting on bill payments within the previous 6 months, and using the nutrition panel frequently when shopping were found to be negatively associated with food insecurity and very low food security after controlling for a number of other demographic, socioeconomic, and behavioral characteristics (September 2017).

"Grocery Purchase Quality Index-2016 Scores Are Moderately Correlated with Healthy Eating Index-2010 Scores in the Food Acquisition and Purchase Survey, 2012–13"by Philip James Brewster, Patricia M. Guenther, Carrie M. Durward, and John F Hurdle, The FASEB Journal, 2017, 31(1). This study evaluates the Grocery Purchase Quality Index-2016 (GPQI-2016), a new tool developed at the University of Utah for assessing household grocery food purchase quality. The GPQI-2016 is based on the expenditure shares for the 29 food categories found in the USDA Food Plans. The authors mapped the food group classifications in the FoodAPS database to the 29 food categories used in USDA's Food Plan market baskets to estimate expenditure shares. The Healthy Eating Index-2010 (HEI-2010) was used as the reference standard; the 8-digit USDA food codes, provided in the FoodAPS database, were used to calculate the HEI-2010. Overall, the association of the GPQI-2016 and the HEI-2010 was moderate, and it varied by component. The process used to map the FoodAPS data to the USDA Food Plan categories could be refined by mapping at the food item level rather than at the food group level and may result in higher correlations in future versions of the GPQI (April 2017).

"Nonresponse and Underreporting Errors Increase over the Data Collection Week Based on Paradata from the National Household Food Acquisition and Purchase Survey"by Mengyao Hu, Garrett W. Gremel, John A. Kirlin, and Brady T. West, The Journal of Nutrition, 2017, 147(5): 964-975. This article looks at the errors associated with food acquisition diary surveys which are important for studying food expenditures, factors affecting food acquisition decisions, and relationships between these decisions and selected measures of health. Because these errors can bias survey estimates and research findings, the authors use paradata to assess survey errors in FoodAPS. To evaluate the patterns of nonresponse over the diary period, the authors fit a multinomial logistic regression model to data from this 1-week diary survey. They also assessed factors influencing respondents’ probability of reporting food acquisition events during the diary process and studied factors influencing respondents’ perceived ease of participation in the survey. As the diary period progressed, nonresponse increased, especially for those starting the survey on Friday (where the odds of a refusal increased by 12 percent with each fielding day). Nonresponse and underreporting of food acquisition events tended to increase in FoodAPS as data collection proceeded. This analysis of paradata available in the FoodAPS revealed these errors and suggests methodological improvements for future food acquisition surveys (March 2017).

"Rethinking Household Demand for Food Diversity"by Andrea M. Leschewski, Dave D. Weatherspoon, and Annemarie Kuhns, British Food Journal, 2017, 119(6): 1176-1188. The authors developed a group-based food diversity index, which represents diversity in household expenditures across food subgroups, by adapting the U.S. Healthy Food Diversity Index. Using FoodAPS data, the results show that the group and product code indices capture different forms of food diversity. Education, gender, age, household size, race, SNAP and food expenditures are found to significantly affect food diversity. However, the magnitude and direction of the effects vary between group and product code indices. Given these differences, it is essential that studies select a diversity index that corresponds to their objective. Results suggest that group-based indices are appropriate for informing food and nutrition policy, while product code-based indices are ideal for guiding food industry management’s decision making (2017).

"Moderation of the Relation of County-Level Cost of Living to Nutrition by the Supplemental Nutrition Assistance Program"—by Sanjay Basu, Christopher Wimer, and Hilary Seligman, American Journal of Public Health, 106 (11): 2064-70. This article uses the National Household Food Acquisition and Purchase Survey (2012–2013; n = 14,313, including 5,414 persons in households participating in the Supplemental Nutrition Assistance Program (SNAP)) to examine associations between county-level cost-of-living metrics and both food acquisitions and the Healthy Eating Index (HEI). The study controls for individual-, household-, and county-level covariates and accounts for unmeasured confounders influencing both area of living and food acquisition. Living in a higher-cost county—particularly one with high rents—was associated with a significantly lower volume of acquired vegetables, fruits, and whole grains; a greater volume of acquired refined grains, fats and oils, and added sugars; and an 11 percent lower HEI score. Participation in SNAP was associated with nutritional improvements among persons living in higher-cost counties (2016). 

"Population Density, Poverty, and Food Retail Access in the United States: An Empirical Approach"—by Parke Wilde, Joseph Llobrera, and Michele Ver Ploeg, International Food and Agribusiness Management Review, 17 (Special Issue A).  This article uses a random sample of census block groups to describe the adequacy of the local food retail environment in the continental United States. It builds upon simple empirical relationships between population density, poverty rates, vehicle access, and proximity to the nearest supermarket. In contrast with the conventional wisdom, the results show that high-poverty block groups had closer proximity to the nearest supermarket than other block groups did, on average: 85.6 percent of high-poverty block groups had a supermarket within 1 mile, while 76.8 percent of lower-poverty block groups had a supermarket within this distance. Population density is a strong predictor of proximity to the nearest supermarket. Block groups with very high population density generally had very close proximity to a nearest supermarket. In block groups lacking a nearby supermarket, rates of automobile access generally were quite high (more than 95 percent), although this still leaves almost 5 percent of the population in these areas lacking both an automobile and a nearby supermarket (2014).

"Food Store Choices of Poor Households: A Discrete Choice Analysis of the National Household Food Acquisition and Purchase Survey (FoodAPS)"—by Rebecca Taylor and Sofia B. Villas-Boas, American Journal of Agricultural Economics 98 (4): 513-32. This article uses FoodAPS data to estimate consumer food outlet choices as a function of outlet type and household attributes in a multinomial mixed logit model. More specifically, the authors allow for the composition of the local retail food environment to play a role in explaining household store choice decisions and food acquisition patterns. The study found that households are willing to pay more per week in distance traveled to shop at superstores, supermarkets, and fast food outlets than at farmers markets and smaller grocery stores, and that willingness to pay is heterogeneous across income group, Supplemental Nutrition Assistance Program participation, and other household and food environment characteristics (July 2016).

"The Effects of Benefit Timing and Income Fungibility on Food Purchasing Decisions among Supplemental Nutrition Assistance Program Households"—by Travis Smith, Joshua P. Berning, Xiaosi Yang, Gregory Colson, and Jeffrey H. Dorfman, American Journal of Agricultural Economics 98 (2): 564-80. This article uses FoodAPS data to examine the "SNAP benefit cycle" where SNAP participants have higher consumption shortly after receiving their benefits, followed by lower consumption toward the end of the benefit month. The authors find evidence of two behavioral responses, working in tandem to drive much of the cycle: (1) short-run impatience—a higher preference to consume today, and (2) fungibility of income—the degree of substitutability between a SNAP dollar and a cash dollar. However, the degree of short-run impatience and fungibility of income are found to differ significantly across poverty levels and use of grocery lists to plan food purchases (January 2016).
