Perspective: Food Access at Dollar Stores and its Implications for Public Health: Report of a Workshop on Identifying Research Priorities. Abstract: The rapid growth of dollar stores as retail sources of food in the United States is a phenomenon with implications for diets, nutrition, and well-being. We convened a broadly interdisciplinary group of researchers and experts from government and academia at the 2-day Food Access at Dollar Stores (FADS) workshop, held in Boston, MA in 2022. The event brought together economists, social scientists, public health researchers and advocates to discuss the concerns and research questions raised by the growth of dollar stores, and their increased role in food retail and access. In-person, moderated discussions on day two of the workshop generated a range of topics considered important for future research. A subsequent survey, using a modified Delphi approach, identified priority research areas. Nine research area categories emerged as a result of discussion at the FADS workshop and received prioritization from the experts: Local Community Impacts; Health and Nutrition Impacts; Policy and Programs; Systemic Issues – Racism, Poverty, and Food Access; Store Offerings and Locations; Shoppers and Customers; Employees and Employment; Corporate Distribution, Strategy, and Marketing; and Dollar Stores vs. Other Food Sources. The growth of dollar stores as food retailers remains an under-researched area of study for food access and nutrition that requires interdisciplinary expertise and collaboration to understand.

Dollar Stores and Food Access for Rural Households in the US, 2008-2020: Abstract: Dollar stores have rapidly expanded their food offerings in recent years. These foods tend to be higher in calories, and lower in nutrients, raising public health concerns, especially in rural and low-income areas where food-access challenges are often greatest. However, there is limited empirical evidence evaluating the impact of this expansion on household food purchases on a national scale. Using data from a yearly, nationally representative panel of approximately 50,000 households, we estimated the share of food purchases from 2008 to 2020 by store type and evaluated the role of dollar stores as food retailers in the United States. We found that dollar stores were the fastest-growing food retailers by household expenditure share (increasing by 89.7%) with rural growth outpacing growth elsewhere (increasing by 102.9%). Though dollar stores still represent a small share of national household food purchases (2.1% in 2020), they play an increasingly prominent role in food-at-home purchases for certain disadvantaged and rural communities. Understanding the quality of the foods they offer and how this may affect diet-related health outcomes is warranted.
