Folks, I know you read this, some of you for some reason read us again and again (and we thank you for it). Generally we are content to do the research and thinking for you, but today I hope you can help us.
For some time I have had a theory that the general population explosion in the South could not have been made possible without the creation of the air-conditioning unit. Recently, while in South Carolina, I made that assertion in mixed company. By mixed company I mean I was the only Yankee amidst an assortment of Southerners... So now I want to test my theory. While it should be fairly easy to track Southern demographic growth via the census, figuring out how to track the spread of air conditioning in the south is a bit harder. Any suggestions? Or comments? (I am sure the massive electrification of the south also had something to do with it as well, though I would welcome any sources on that as well, aside from Robert Caro's biography of Johnson)
