I've been trying to figure out whether alcohol poisoning, underage drinking, etc. is getting better, worse or staying the same, and whether regional differences in laws, enforcement and culture have any noticeable impact. I ran across this graph, and was sort of staring at it when I realized that it looks kind of like college kiddies drink more when the economy tanks and drink less at the peak of the business cycle, and then underneath all that there's a long term decrease.
Which sort of suggests that a really good way to reduce drinking among college kiddies might be to, you know, get the economy going again.
But I'm doing this off of eye-smooth, so it'll probably turn out the effect isn't statistically significant at all.
