What drives Menlo Park’s History grade

HistoryA character grade: shown, never part of Menlo Park’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 Menlo Park’s 1.5 sits above most of its state (79% of California towns have fewer) while its 5 historic buildings outnumber those of 70% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from C to B. The pre-1940 share (±1.9 points) is firm at this size. The founding year is the first post office, not a stated founding date.
