HistoryA character grade: shown, never part of Elsinboro 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 Elsinboro Township’s 47.6 sits above most of its state (81% of New Jersey towns have fewer) while its 4 listings outnumber those of 68% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would still be A−. The pre-1940 share is a Census survey estimate (±8.5 points). Two sources give 1798.
