The Sacramento metropolitan area as you've drawn it makes no sense.
Do you have a suggestion on a different way to do it?
No, of course not. They never do.
Sometimes they do. I got some helpful feedback on
my redivision of the 50 states a couple of years ago. Of course to get the flexibility to make changes, I only required that the states be no less than half nor more than double the average population. You can see the population spread in my treatment of Sacto and the Pacific NW.
Ecotopia (with principal city) and population in millions:
Duwamish (Seattle) 4.7
Chinook (Portland) 3.6
Shasta (Sacramento) 3.6
Ohlone (San Francisco) 9.5
