      I remember years ago seeing some data discussing people moving west and south more, partly in conjunction with the invention of air conditioning, as well as certain roads.

      I think this was one of the maps showing this.

      The boom caused by the construction of Hoover Dam occurred in the 1930’s. Residential air conditioning didn’t really become a thing until well after WWII, closer to 1950.

        Yes, that’s pretty much the point I was making. It was another major factor in Las Vegas being almost completely undeveloped in 1947 as per the photo. Same with the current major cities in Arizona, etc.
