Wine, Not Crime
Let’s presume this data is correct.
Now, let’s speculate.
What does it mean that there is negative correlation between between violent crime in the United States and wine sales? That’s what this graph shows. I don’t think we can suggest that is a causality between the two. Drinking wine may be a great thing on many levels but it’s doubtful that the more wine you drink the less crime you commit.
However, it strikes me that that there is a correlation between disposable income and crime: the more disposable income the nation as a whole has, the less reason to commit crimes simply because more people are able meet their commitments. Also, when the economy is on the rise and more folks have more disposable income, things like wine, jewelry and art see increases in sales.
