Economic Perspectives on Porn

I thought that this map was very interesting. Can you guess what is it comparing? This map depicts the number of internet subscriptions to pornographic websites per capita by state. Very interesting. It was published (here) in the Journal of Economic Perspectives 2009, Vol. 23 (1), 209-220 where you can find the numbers that go with it on page 216. I excluded the legend so you would go to the source to find it (which is a practice I highly encourage). There are more interesting statistics like this in the article. And finally some more fun facts.
