More historic than 54% of U.S. towns, on its age, its old homes and the National Register.
On its age, its old homes and the National Register, Sumner is more historic than 54% of U.S. towns. Its share of homes from before 1940 holds the grade up; its National Register listings pull it down.
Few Illinois towns list much on the Register (a typical Illinois town has 0.5 per 10,000 residents, the U.S. 2.4), so Sumner’s 0.0 sits below most of its state (28% of Illinois towns have fewer) while its 0 listings outnumber those of 23% of U.S. towns.

From Wikipedia’s history of Sumner.
Sumner was established as a stop along the Ohio and Mississippi Railway in the early 1850s. Initially known as "Black Jack" when a post office was opened in 1852, the city was renamed for Benjamin Sumner, an early settler, in 1855. Sumner incorporated in 1887.

The Sumner post office opened in 1855, the earliest record of the town by name (U.S. post office records).
Sumner is more historic than 54% 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.
38% of Sumner’s homes were built before 1940 (Census estimate, ±13.6 points), against a typical 11% for an Illinois town; the median home was built in 1954.
