History grade
What drives Belleville Township’s History grade
On its age, its old homes and the National Register, Belleville Township is more historic than 78% of U.S. towns, #130 of 468 in New Jersey. Its share of homes from before 1940 holds the grade up; its National Register listings pull it down.
A−
HistoryA character grade: shown, never part of Belleville 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 Belleville Township’s 0.3 sits below most of its state (24% of New Jersey towns have fewer) while its 1 listings outnumber those of 51% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from B to A. The pre-1940 share (±2.9 points) is firm at this size. The founding year is the first post office, not a stated founding date; Wikidata’s 1839 falls in the same era, so the grade doesn’t depend on which one is used.

Originally known as "Second River" or "Washington", the inhabitants renamed the settlement "Belleville" in 1797. Belleville was originally incorporated as a township by an act of the New Jersey Legislature on April 8, 1839, from portions of Bloomfield. Portions of the township were taken to create Woodside Township (March 24, 1869, now defunct) and Franklin Township (February 18, 1874, now known as Nutley). The independent municipality of Belleville city was created within the township on March 27, 1874, and was dissolved on February 22, 1876. On November 16, 1910, Belleville was reincorporated as a town, based on the results of a referendum held eight days earlier.
