HistoryA character grade: shown, never part of Allamuchy Township’s overall grade.
New Jersey towns list more on the Register than most of the country (a typical New Jersey town has 3.7 per 10,000 residents, the U.S. 2.4), so Allamuchy Township’s 3.7 sits near the middle of its state (49% of New Jersey towns have fewer) while its 2 historic buildings outnumber those of 60% 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 (±2.6 points) is firm at this size. The founding year is the first post office, not a stated founding date; Wikidata gives 1873.
