Yesterday we have just shared a heat map about Americans health index in the past 30 years, and here we find a detailed pie chart about obesity situation in various states.
Size of each pie chart indicates total population size rather than obesity situation, and the detailed obesity status can refer to the percentage break down. Mouseover the pie charts, and you can get detailed population information. This map is interactive enough that you can see the changes from 1995 to 2011 by clicking the Play button in the bottom.
Check the above map and see if you are agree with the study.
