On its age, its old homes and the National Register, Thayer is more historic than 49% of U.S. towns. Its National Register listings hold the grade up; its age pulls 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 Thayer’s 4.3 sits near the middle of its state (61% of Missouri towns have fewer) while its 1 listings outnumber those of 51% of U.S. towns.

From Wikipedia’s history of Thayer.
A post office called Thayer has been in operation since 1884. The community has the name of Nathaniel Thayer, a railroad promoter.
Thayer is considered a railroad town, as it was laid out in 1882 to be a division point. At the turn of the 20th century, 400 railroad men lived in Thayer. Currently, the Burlington Northern Santa Fe railroad travels through town.

Thayer is more historic than 49% 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.
One place: the Church of the Holy Trinity (listed 2017).
13% of Thayer’s homes were built before 1940 (Census estimate, ±4.8 points), against a typical 8.4% for a Missouri town; the median home was built in 1971.
