HistoryA character grade: shown, never part of Marlboro 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 Marlboro Township’s 0.5 sits below most of its state (26% of New Jersey towns have fewer) while its 2 listings 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 (±1.2 points) is firm at this size. The founding year is the first post office, not a stated founding date; Wikidata’s 1848 falls in the same era, so the grade doesn’t depend on which one is used.
Founding year: the first post office (other dates in Quick answers). Homes: Census ACS 2020–24.
