What drives Montague’s History grade

C
HistoryA character grade: shown, never part of Montague’s overall grade.
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.
