What drives McKinleyville’s History grade

On its age, its old homes and the National Register, McKinleyville is more historic than 11% of U.S. towns, #658 of 847 in California. Its National Register listings hold the grade up; its age pulls it down.

Few California towns list much on the Register (a typical California town has 0.0 per 10,000 residents, the U.S. 2.4), so McKinleyville’s 0.0 sits below most of its state (31% of California towns have fewer) while its 0 listings outnumber those of 23% 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 (±2.5 points) is firm at this size. The founding year is the first post office, not a stated founding date.
