I'm assuming this map is based on a classification model that was fit to the demographics listed for each state, and that you are presenting the solution it gave you without further modification. It would be nice if you would describe the specific classification model and parameters you used, because I worry that some people might assume you just made up a bunch of regions on your own inspection and gave them alt-hist-style names -- they'll be hoping this is still a data sub and not a sci-fi/fantasy/Kevin-Costner-film-trivia sub.
