Food Systems

Access to consistent, affordable nutrition is essential. Low-income and rural people in the United States may have limited access because of their distance to affordable food outlets and other factors.[1] Grocery chains often judge that they will not be profitable in low-income or low-density areas,[2] leaving low-income and rural residents to travel longer distances to shop for groceries or buy from expensive outlets, like convenience stores or fast-food restaurants.[3],[4],[5] In addition, higher food costs may leave people and households unable to afford consistent meals. Food insecurity as measured by enrollment in SNAP and geographic proximity to grocery stores were selected as indicators to understand equity in local food systems.
