HistoryA character grade: shown, never part of Hauula’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 Hauula’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.
