Food desert
Summary
A food desert is an area that has limited access to affordable and nutritious food. In contrast, an area with greater access to supermarkets and vegetable shops with fresh foods may be called a food oasis. The designation considers the type and the quality of food available to the population, in addition to the accessibility of the food through the size and the proximity of the food stores.
In 2017, the United States Department of Agriculture reported that 39.5 million people or 12.8% of the population were living in low-income and low-access areas. Of this number, 19 million people live in "food deserts", low-income census tracts that are more than one mile from a supermarket in urban or suburban areas and more than 10 miles from a supermarket in rural areas.
Food deserts tend to be inhabited by low-income residents with inadequate access to transportation, which makes them less attractive markets for large supermarket chains. These areas lack suppliers of fresh foods, such as meats, fruits, and vegetables. Instead, available foods are likely to be processed and high in sugar and fats, which are known contributors to obesity in the United States.
However, a number of studies suggest that poor health in "food deserts" is primarily caused by differences in demand for healthy food, rather than differences in availability.
By 1973, the term "desert" was ascribed to suburban areas lacking amenities important for community development. A report by Cummins and Macintyre states that a resident of public housing in western Scotland supposedly coined the more specific phrase "food desert" in the early 1990s. The phrase was first officially used in a 1995 document from a policy working group on the Low Income Project Team of the UK's Nutrition Task Force.
Initial research was narrowed to the impact of retail migration from the urban center. More recent studies explored the impact of food deserts in other geographic areas (such as rural and frontier) and among specific populations like minorities and the elderly.
