B+
HistoryA character grade: shown, never part of Ogdensburg’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 Ogdensburg’s 46.3 sits above most of its state (80% 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 is a Census survey estimate (±7.0 points). The founding year is the first post office, not a stated founding date; Wikidata gives 1914.

Ogdensburg, in brief
Wikipedia doesn’t have a history of Ogdensburg yet. The photos, dates and memories neighbors add here are how it gets written.
Ogdensburg is a borough in Sussex County, in the U.S. state of New Jersey. As of the 2020 United States census, the borough's population was 2,258, a decrease of 152 (−6.3%) from the 2010 census count of 2,410, which in turn reflected a decline of 228 (−8.6%) from the 2,638 counted in the 2000 census. The borough was formed based on an Act of the New Jersey Legislature on February 26, 1914, from part of Sparta Township, subject to the results of a referendum held on March 31, 1914. Ogdensburg is named after its first settler, Robert Ogden. New Jersey Monthly magazine ranked Ogdensburg as its 27th best place to live in its 2008 rankings of the "Best Places To Live" in New Jersey.
Its first post office opened in 1860. Between the 2010 and 2020 censuses its population fell from 2,410 to 2,258 (-6%).
