Each state boarder is low density farm fields, pastures, and deserts. No boarders with houses tight to the line. At lease 100 feet on both sides (200 feet total).
Then size states by population. ~20 million in each state.
Places with super low density are no longer states, but territories. Maybe less than 1 person per square mile within a 10 mile radius. (For all such 10 mile radiuses.) More than that within the radius, then part of a state.
