Few California towns list much on the Register (a typical California town has 0.0 per 10,000 residents, the U.S. 2.4), so Green Acres’ 0.0 sits below most of its state (31% of California towns have fewer) while its 0 listings outnumber those of 23% of U.S. towns.
How sure. Graded on two of the three inputs, so a change in either one moves the letter more than it would with three. The pre-1940 share is a Census survey estimate (±21.6 points).
