What drives Robbinsville Township’s History grade

On its age, its old homes and the National Register, Robbinsville Township is more historic than 46% of U.S. towns, #324 of 468 in New Jersey. Its National Register listings hold the grade up; its share of homes from before 1940 pulls it down.

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 Robbinsville Township’s 39.6 sits above most of its state (79% of New Jersey towns have fewer) while its 62 historic buildings outnumber those of 86% 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 (±1.4 points) is firm at this size. The founding year is the first post office, not a stated founding date; Wikidata’s 1859 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. National Register: National Park Service, May 2026 list; each listing counted once (boundary changes and added documentation belong to their listing), and a historic district counts its contributing buildings.

The story

How Robbinsville Township came to be

From Wikipedia’s history of Robbinsville Township.

Read it all →

What is now Robbinsville Township was originally incorporated as Washington Township (named for George Washington) by an act of the New Jersey Legislature on March 15, 1859, from portions of East Windsor.

On November 6, 2007, voters approved by a vote of 1,816 to 693 a measure that changed the township's name from Washington Township (the name of five other municipalities in New Jersey) to Robbinsville, named after a settlement within the township. The official changeover took place January 1, 2008, as signs and other items with "Washington" on them began to be changed. It is named for George R. Robbins, who served in the United States House of Representatives from 1855 to 1859 and lived in the area.
