As American cities have seen a change in land uses in urban areas, with stores moving to suburban areas increasing the reliance on cars, many urban areas are left with a lack of accessible quality food options. These “food desert” locations, where residents lack both access and sufficient economic resources to purchase healthy food, result in health disparities for residents in these communities. Decades of population loss in Baltimore have resulted in nearly one in four residents living in food deserts. Using a food acquisition questionnaire, this study analyses the travel patterns of 500 residents in Baltimore City. The study found that most residents, regardless of vehicle ownership, do not shop at their nearest grocery store. However, those who own vehicles shop more frequently. The study showed that grocery delivery services do not yet close the food accessibility gap as adoption was positively correlated with income. The findings suggest that current food desert metrics should deemphasize distance to the nearest grocery store and instead look at the number and variety of stores accessible within a given time or distance.
