More historic than 29% of U.S. towns. What drives it
Below: maps from 1916 on and the census since 1890.
The Seymour post office opened in 1881, the earliest record of the town by name.
More historic than 29% of U.S. towns, on its age, its old homes and the National Register.
On its age, its old homes and the National Register, Seymour is more historic than 29% of U.S. towns. Its share of homes from before 1940 holds the grade up; its National Register listings pull it down.
Missouri towns list about as much on the Register as the country (a typical Missouri town has 2.4 per 10,000 residents, the U.S. 2.4), so Seymour’s 0.0 sits below most of its state (23% of Missouri towns have fewer) while its 0 listings outnumber those of 23% of U.S. towns.
Founding year: the first post office (other dates in Quick answers). Homes: Census ACS 2020–24. National Register: National Park Service, May 2026 list; each listing counted once (boundary changes and added documentation belong to their listing), and a historic district counts its contributing buildings.

Seymour is more historic than 29% 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.
11% of Seymour’s homes were built before 1940 (Census estimate, ±5.8 points), against a typical 8.4% for a Missouri town; the median home was built in 1982.
