HistoryA character grade: shown, never part of Royal Kunia’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 Royal Kunia’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 two of the three inputs, so a change in either one moves the letter more than it would with three. The pre-1940 share (±0.4 points) is firm at this size.
