These maps are to show the correlation in McDonald's locations and obesity rates taken in 2008. The darker areas on the second map show the highest obesity rate in America, and unsurprisingly the most fast food locations in each area.
These maps were taken from an article entitled; 'Causation or Correlation?'. This argument can be valid on both sides. On one hand the fact that there are easy and cheap ways to access fast food can cause obesity to rise, however i believe it is the attitude by some Americans. Some people find it easier to grab a McDonalds than to cook. No matter how many fast food restaurants are in each city, people with the wrong attitude to food will be obese.
