What drives Union City’s History grade

On its age, its old homes and the National Register, Union City is more historic than 66% of U.S. towns, #208 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 Union City’s 1.2 sits below most of its state (34% of New Jersey towns have fewer) while its 8 historic buildings outnumber those of 74% of U.S. towns.

How sure. Graded on any two of the three inputs instead, the letter would range from C+ to A−. The pre-1940 share (±2.3 points) is firm at this size.

Founding year: the first census (other dates in Quick answers). Homes: Census ACS 2020–24.

The story

How Union City came to be

From Wikipedia’s history of Union City.

Read it all →

The area of what is today Union City was originally inhabited by the Munsee-speaking branch of Lenape Native Americans, who wandered into the vast woodland area encountered by Henry Hudson during the voyages he conducted from 1609 to 1610 for the Dutch, who later claimed the area (which included the future New York City) and named it New Netherland. The portion of that land that included the future Hudson County was purchased from members of the Hackensack tribe of the Lenni-Lenape and became part of Pavonia, New Netherland.
