HistoryA character grade: shown, never part of Hanamaulu’s overall grade.
Few Hawaii towns list much on the Register (a typical Hawaii town has 0.0 per 10,000 residents, the U.S. 2.4), so Hanamaulu’s 0.0 sits below most of its state (28% of Hawaii 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 D− to D. The pre-1940 share (±0.9 points) is firm at this size. The founding year is the first post office, not a stated founding date.
