In Nashville, you're not going to hear many people ask for a "pop"...and if they do, they will probably be met with laughter and at least one person repeating the word with a midwestern accent.
In the north and midwest, you mostly hear pop but people still call it soda.
AND THEN there are the parts of the country that refer to all carbonated drinks as Coke.
SO what does the majority of the US say?!
According to a survey done, it's a much tighter race than you may expect!
Out of the 401,414 people surveyed, 39.2% called it pop and 40.8% called it soda (sorry "Coke" people, that falls at only 14%)!
