More historic than 57% of U.S. towns, on its age, its old homes and the National Register.
On its age, its old homes and the National Register, Chelsea is more historic than 57% of U.S. towns. Its National Register listings hold the grade up; its age pulls it down.
Oklahoma towns list more on the Register than most of the country (a typical Oklahoma town has 5.9 per 10,000 residents, the U.S. 2.4), so Chelsea’s 16.0 sits above most of its state (75% of Oklahoma towns have fewer) while its 3 listings outnumber those of 65% of U.S. towns.

From Wikipedia’s history of Chelsea.
In 1881, Chelsea began as a stop on the Atlantic and Pacific Railroad. A post office was established in November 1882. The community incorporated as a town in the Cherokee Nation, Indian Territory, in 1889. The town was surveyed and platted in 1902. The Bank of Chelsea, the first state bank in Indian Territory, began operation in March 1896.

The Chelsea post office opened in 1882, the earliest record of the town by name (U.S. post office records).
Chelsea is more historic than 57% 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.
Three places: the Hogue House (listed 1982), the Chelsea Motel (2004) and the Pryor Creek Bridge (2006).
13% of Chelsea’s homes were built before 1940 (Census estimate, ±4.7 points), against a typical 7.0% for an Oklahoma town; the median home was built in 1971.
