HistoryA character grade: shown, never part of Union City’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 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.

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.
The Union City post office opened in 1870, the earliest record of the town by name (U.S. post office records).
