I think the map is only considering the amount of area, not specific geographical regions.
Geographical area does not represent population, though many people assume it does. In fact, the central part of the US has only a small part of the general population.
Glad the central part of the US doesn't have population, just food. How will sanctuary cities fare, when the National Guard cuts off all food going into them?
Ok, that's it. I'm just ignoring you from here on...
