On its age, its old homes and the National Register, Millburn Township is more historic than 83% of U.S. towns, #96 of 468 in New Jersey. Its share of homes from before 1940 holds the grade up; its age 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 Millburn Township’s 56.4 sits above most of its state (82% of New Jersey towns have fewer) while its 125 historic buildings outnumber those of 91% 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 is a Census survey estimate (±3.0 points). The founding year is the first post office, not a stated founding date.
