History grade
What drives Morenci’s History grade
On its age, its old homes and the National Register, Morenci is more historic than 19% of U.S. towns. Its age holds the grade up; its share of homes from before 1940 pulls it down.
C−
HistoryA character grade: shown, never part of Morenci’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 Morenci’s 0.0 sits below most of its state (29% of Arizona 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 still be C−. The pre-1940 share is a Census survey estimate (±4.7 points). The founding year is the first post office, not a stated founding date.

The story so far
Morenci, in brief
Wikipedia doesn’t have a history of Morenci yet. The photos, dates and memories neighbors add here are how it gets written.
Morenci is a census-designated place (CDP) and company town in Greenlee County, Arizona, United States, and was founded by the Detroit Copper Mining Company of Arizona. The population was 2,000 at the 2000 census and 1,489 at the 2010 census. The biggest employer in Morenci (and in nearby Clifton) and the owner of the town is Freeport-McMoRan, the owner of the Morenci Mine, the largest copper mining operation in North America, and one of the largest copper mines in the world. The town was a site of the Arizona Copper Mine Strike of 1983. The large open-pit mine is north of the town.
Its first post office opened in 1884. Between the 2010 and 2020 censuses its population grew from 1,489 to 2,028 (+36%).
