| Meh. They only tested 838 teens. That's a small number to base statistics for an entire nation on. Plus, they mention Chicago a lot, so I'm guessing all the testing was primarily done on teens in Chicago. Even 838 teens in Chicago is a small number to base statistics on. Hell, I went to highschool with almost 5,000 students. This was just one school around my city.
Next study, please.
