What drives Oak Harbor’s History grade

On its age, its old homes and the National Register, Oak Harbor is more historic than 27% of U.S. towns, #146 of 285 in Washington. Its National Register listings hold the grade up; its share of homes from before 1940 pulls it down.

Washington towns of 2,500+ (285)Ahead of 49%

Few Washington towns list much on the Register (a typical Washington town has 0.1 per 10,000 residents, the U.S. 2.4), so Oak Harbor’s 0.4 sits near the middle of its state (57% of Washington towns have fewer) while its 1 listings outnumber those of 51% of U.S. towns.

How sure. Graded on any two of the three inputs instead, the letter would range from C− to C+. The pre-1940 share (±0.9 points) is firm at this size. The founding year is the first post office, not a stated founding date; Wikidata gives 1915.

Founding year: the first post office (other dates in Quick answers). Homes: Census ACS 2020–24. National Register: National Park Service, May 2026 list; each listing counted once (boundary changes and added documentation belong to their listing), and a historic district counts its contributing buildings.
