HistoryA character grade: shown, never part of Boise City’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 Boise City’s 8.9 sits near the middle of its state (62% of Oklahoma 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 B+. The pre-1940 share is a Census survey estimate (±7.5 points). The founding year is the first post office, not a stated founding date.

What stands out about Boise City’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
Boise City was founded in 1908 by developers J. E. Stanley, A. J. Kline, and W. T. Douglas (all doing business as the Southwestern Immigration and Development Company of Guthrie, Oklahoma), who published and distributed brochures promoting the town as an elegant, tree-lined city with paved streets, numerous businesses, railroad service, and an artesian well. They sold 3,000 lots to buyers who discovered, on their arrival, that none of the information in the brochure was true. In addition to using false publicity, the three men did not have title to the lots they sold.
