HistoryA character grade: shown, never part of Frederick’s overall grade.
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 Frederick’s 5.8 sits near the middle of its state (53% of Oklahoma towns have fewer) while its 2 listings outnumber those of 60% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from D to C+. The pre-1940 share (±2.1 points) is firm at this size. The founding year is the first post office, not a stated founding date.

Originally established in 1901, the Frederick area was among the last of the Oklahoma Territory land to be opened to settlement. What is now Frederick used to be two towns: Gosnell and Hazel. Both towns were established in 1901, when the Kiowa-Comanche-Apache reservation was opened to settlement. In 1902 the towns combined in order to take advantage of the Blackwell, Enid and Southwestern Railway. The new town was named Frederick, after the son of a railroad executive. Gosnell received the depot, and the residents of Hazel moved north to the new town of Frederick. The post office moved from Gosnell to Frederick, for which it was renamed in 1902.
