Yeah, I'm not sure what the author[0] means there either. I looked through the latest Census and I couldn't find any sufficient data on "hippies", as there was not a question for that[1]. If there is no data on it, how can one make the dubious claim that one is "full of"[2] them? I really wish this article was more well researched[3].

[0] by author I am referring to the author of the article which this thread is talking about

[2] by "full of" I assume a simple majority
