What drives Warren Township’s History grade

On its age, its old homes and the National Register, Warren Township is more historic than 63% of U.S. towns, #230 of 468 in New Jersey. Its age holds 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 Warren Township’s 6.2 sits near the middle of its state (61% of New Jersey towns have fewer) while its 10 historic buildings outnumber those of 76% 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 (±1.7 points) is firm at this size. Two sources give 1806.

The story

How Warren Township came to be

From Wikipedia’s history of Warren Township.

Read it all →

Warren was originally inhabited by the Lenape Native Americans and was colonized in the 1720s by European farmers. As early as 1900, it became a destination for wealthy residents looking to escape nearby New York City. Warren was incorporated as a township by an act of the New Jersey Legislature on March 5, 1806, from portions of Bernards Township and Bridgewater Township. The south-eastern half of the original township (which was close to a railroad and contained most of the population) was separated off as North Plainfield Township (since renamed to Green Brook Township) on April 2, 1872.
