hampers physical activity, thus negatively impacting a child's health. This issue contradicts the belief held by many in the United States that children who come from high-income homes are less likely to become obese as they can be active in safe environmental spaces. Technology also plays a detrimental role for adults who spend most of their time working on a computer. Economists from the Milken Institute, working with statistics from the United States, correlated a 10% increase in the sale of technology with a 1.4% increase in obesity rates – approximately 4.2 million people in a country with the same population as the United States. This increase in time spent using technology not only absorbs time potentially spent being active, it also changes the way people eat. Employees may feel pressured while at work and may eat hurriedly or absentmindedly; once home, workers frequently turn on the TV or engage in their mobile phones instead of focusing on their food consumption and diet. Ross DeVol, a chief research officer at the Milken Institute, quipped: "Common sense says if you sit around in front of the screen, don't exercise while you are working, change your diet...you are going to gain weight." Food access in the United States Federal and national level studies In 2009, the U.S. Department of Agriculture conducted a food desert study to examine the public's access to supermarkets. Evidence showed that 23.5 million people within the United States did not have access to a supermarket within a one-mile radius of their residence. More than 113 studies have been conducted to determine if healthy food and supermarkets are equally distributed and accessible to every socioeconomic class. Of these, 85% (97) of the studies found that supermarkets and healthy food stores are unequally distributed between different socioeconomic groups. Other research teams have studied the comparison between supermarkets and smaller food outlets such as small grocery stores and convenience stores. They found that supermarkets were used as a proxy for food access as they provide the most reliable access to a wide variety of nutritious and affordable food. The study showed that low-income and minority communities had less supermarkets and more convenience and small grocery stores as compared to predominantly wealthy and White communities. 89 out of the 98 (90%) studies of national data indicated that urban areas have uneven geographic access to supermarkets. National studies have concluded that ZIP codes
