Answers:
in my town I ponder 90% of ethnic group are alcoholics, and that may be on the low wrap up. We hold 7 bar surrounded by town and no stores...lately have to share
Worldwide, probably fundamental 60 or more. Some religions don't aprove alcohol.
This is a guess, but I would estimate 75% overall. Younger empire, I would put at 85% and elder at 65%.
Sometimes, I engineer up for those that don't drink. :-o
In America I once read that 90% of the grown population drink alcohol at lowest socially. Not to utter they are alcoholics but will own a drink at weddings etc. It sounds beliveable to me.
