HistoryA character grade: shown, never part of Carlton’s overall grade.
Oregon towns list more on the Register than most of the country (a typical Oregon town has 2.9 per 10,000 residents, the U.S. 2.4), so Carlton’s 7.2 sits near the middle of its state (62% of Oregon 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 C to B−. The pre-1940 share is a Census survey estimate (±8.3 points). The founding year is the first post office, not a stated founding date; Wikidata’s 1899 falls in the same era, so the grade doesn’t depend on which one is used.

What stands out about Carlton’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
The origin of Carlton's name is disputed. An ex-county commissioner claims that the name was derived from Wilson Carl, whereas A. E. Bones, postmaster at Carlton, stated in a 1925 letter that it was named for John Carl Sr., at the request of R. R. Thompson. These men may have been part of the same family.
Carlton post office was established in 1874, with F. J. Fryer serving as its first postmaster.
