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 Montague’s 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 any two of the three inputs instead, the letter would range from C− to C+. The pre-1940 share is a Census survey estimate (±6.1 points). The founding year is the first post office, not a stated founding date.
