What drives Garden City’s History grade
On its age, its old homes and the National Register, Garden City is more historic than 78% of U.S. towns, #454 of 758 in New York. Its share of homes from before 1940 holds the grade up; its age pulls it down.

HistoryA character grade: shown, never part of Garden City’s overall grade.
New York towns list more on the Register than most of the country (a typical New York town has 12.3 per 10,000 residents, the U.S. 2.4), so Garden City’s 24.0 sits near the middle of its state (59% of New York towns have fewer) while its 55 historic buildings outnumber those of 86% 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 (±3.6 points). Two sources give 1869.

In 1869, according to Wikidata. Garden City’s post office opened in 1875, and the census of 1880 counted 574 people here.
