The Consequences of Living in a Small-town Food Desert: Mixed Methods Evidence from a Quasi-Experiment

Abstract

Past research finds that living in a food desert is associated with an unhealthy diet and poor health; however, more recent studies of urban food deserts suggest that these findings may be spurious. In this article, we leverage the flooding and subsequent closing of the only grocery store in a small town to examine the effects of living in a small-town food desert. Using difference-in-difference methods, we find that opening a grocery store in a small-town food desert is not associated with changes in diet, but we find that opening a grocery store in a food desert is associated with improved food access. Findings from in-depth interviews shed further light on how residents of a small-town food desert decide where to shop and how routine activities provide access to a range of nonlocal grocery stores. Moreover, we find that the absence of a grocery store negatively affects social relationships. While the findings add to growing skepticism about food desert effects on diet, the findings reveal important food desert effects on food access and also the social consequences of living in a food desert.
