I'd love to see the drinking stats for male millennials over the past 15 to 20 years. I bet there's a big drop as they age out of prime beer drinking age and start moving into middle age. I say this as I'm part of that demographic, and I hardly drink anymore after having one or 2 craft beers a night in my 20s.

Edit: The downturn in drinking has huge ramifications for restaurants as they make a lot of profit on alcohol.
