These is the kind of demographic statistics that I love the most. This Article talks about different names people have for soda. See, I said SODA. I've never really thought about calling it anything else.

The results are actually mapped out, which shows significant regional differences. Curiously, all three places in the US where I've lived (Milwaukee, St. Louis, and California) are specifically mentioned as 'soda' stongholds. Interesting indeed!
