In 1973 Dr Pearcy published this booklet on the potential reassessment of U.S. state boundaries. The 38 states were informed by population, major cities, water basins, etc. The idea came to him after watching the migrations around WWII and how populations had shifted. Much had changed since the 18th and 19th century when many states were first made.

I still don't that's how you'd divide California.
