HistoryA character grade: shown, never part of Delanco Township’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 Delanco Township’s 16.4 sits above most of its state (74% 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 B to A. The pre-1940 share is a Census survey estimate (±8.1 points). The founding year is the first post office, not a stated founding date; Wikidata’s 1859 falls in the same era, so the grade doesn’t depend on which one is used.

What stands out about Delanco Township’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
What is now Delanco Township was originally incorporated as Beverly Township by an act of the New Jersey Legislature on March 1, 1859, within Willingboro Township. Delanco was a geographical place name by 1868, and probably earlier. At its creation, Beverly Township included Beverly city, which separated as an independent municipality c. 1877. Portions of the township were taken to create Edgewater Park on February 26, 1924. The township's name was changed to Delanco Township as of December 20, 1926, based on the results of a referendum held on November 2, 1926.
