More historic than 65% of U.S. towns. What drives it
Most of Tompkins was built recently: 9% of its homes predate 1940 and the median home dates from 1992. Its Register listings are the Common School 32 and the Rock Rift Fire Observation Tower. Below: maps from 1924 on and the census since 1820.
The Tompkins post office opened in 1812, the earliest record of the town by name. Five smaller post offices, Rock Rift (1850), Apex (1881) and Read Creek (1882), opened inside today’s town and later closed.
More historic than 65% of U.S. towns, on its age, its old homes and the National Register.
On its age, its old homes and the National Register, Tompkins is more historic than 65% of U.S. towns. Its age holds the grade up; its share of homes from before 1940 pulls it down.
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 Tompkins’ 16.8 sits near the middle of its state (54% of New York towns have fewer) while its 2 listings outnumber those of 60% of U.S. towns.

The Tompkins post office opened in 1812, the earliest record of the town by name (U.S. post office records).
Tompkins is more historic than 65% of U.S. towns. The History grade combines the town’s founding era, the share of homes built before 1940 and its National Register listings. It’s a character grade, so it isn’t part of the overall grade. How it works.
Two places: the Common School 32 (listed 2017) and the Rock Rift Fire Observation Tower (2018).
9% of Tompkins’ homes were built before 1940 (Census estimate, ±3.6 points), against a typical 27% for a New York town; the median home was built in 1992.
