Via the Columbia Stats blog, we learn that there is a strong negative relationship between the number of Starbucks per capita and the number of Walmarts per capita. This isn’t surprising, but it is informative. It also means that people who don’t like expensive coffee or cheap Chinese crap should all move to Vermont.
Failing that, New Jersey or Rhode Island look to be islands of sanity. It is worth noting that Rhode Island is also one of the few states in which NCSE has not tracked any creationist activity over the last few years, suggesting that it has a very strong claim to sanity.
I invite speculation about possible causes for this remarkable relationship. My suggestion, in the title, is that Walmarts somehow poison the ground, preventing successful Starbucks colonization. Or vice versa.
