Distance to grocery stores and vehicle access influence where low-income households shop for food
Households that struggle to get to large grocery stores may rely on close by sources of food such as convenience stores or fast-food restaurants that generally provide a smaller variety of healthy foods. A recent ERS study used data from USDA’s National Household Food Acquisition and Purchase Survey (FoodAPS) to examine if food shopping behaviors of access-burdened households—those that live more than 0.5 of a mile from a SNAP-authorized supermarket or superstore and do not have a vehicle—differ from households that live within 0.5 of a mile of these stores or have their own vehicle (sufficient-access households). Looking only at SNAP and low-income non-SNAP households, the researchers found that 74 percent of access-burdened households visited a supermarket, superstore, or large grocery store during an average week in 2012, compared to 85 percent of sufficient-access households. Access-burdened households did not appear to substitute convenience stores and restaurants for visits to large grocers; only 63 percent of access-burdened households visited an eating place compared with 78 percent of sufficient-access households, and differences in convenience store visits were not statistically significant. The data for this chart are drawn from the ERS report, The Influence of Food Store Access on Grocery Shopping and Food Spending, released on October 18, 2017.
