HistoryA character grade: shown, never part of Benson’s overall grade.
Few Arizona towns list much on the Register (a typical Arizona town has 0.1 per 10,000 residents, the U.S. 2.4), so Benson’s 126 sits above most of its state (95% of Arizona towns have fewer) while its 68 historic buildings outnumber those of 87% 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 (±2.8 points) is firm at this size. The founding year is the first post office, not a stated founding date.

The city was founded in 1880 when the Southern Pacific Railroad came through. It was named after Judge William S. Benson, a friend of Charles Crocker, president of the Southern Pacific. The railroad, coming overland from California, chose the Benson site to cross the San Pedro River. Benson then served as a rail junction point to obtain ore and refined metal by wagon, in turn shipping rail freight back to the mines at Tombstone, Fairbank, Contention City and Bisbee. For example, the railhead in Benson was about 25 miles (40 km) from Tombstone, and was the closest rail connection to it until 1882, when a feeder line was laid from Benson to Contention City.
