HistoryA character grade: shown, never part of Seaside Park’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 Seaside Park’s 5.6 sits near the middle of its state (59% of New Jersey towns have fewer) while its 1 listings outnumber those of 51% 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 is a Census survey estimate (±4.3 points). The founding year is the first post office, not a stated founding date; Wikidata’s 1898 falls in the same era, so the grade doesn’t depend on which one is used.

What stands out about Seaside Park’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
The first inhabitants of the barrier island were Lenape Native Americans who came in search of fish, crabs, clams, and scallops. They called this area "Seheyichbi," meaning land bordering the ocean. The Atlantic Ocean provided more than food; these people began using shells in place of wooden beads as their form of currency. These Native Americans, who stayed during the summer and went inland for winter, were part of the principal Algonquian tribe that lived mainly on and around the North American Seaboard. The Algonquians in New Jersey called themselves "Lenni Lenape", which means "original people."
