What drives Alcoa’s History grade

HistoryA character grade: shown, never part of Alcoa’s overall grade.
Tennessee towns list more on the Register than most of the country (a typical Tennessee town has 6.1 per 10,000 residents, the U.S. 2.4), so Alcoa’s 1.6 sits near the middle of its state (37% of Tennessee 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 D to B−. The pre-1940 share is a Census survey estimate (±4.2 points). The founding year is the first post office, not a stated founding date; Wikidata’s 1919 falls in the same era, so the grade doesn’t depend on which one is used.
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.

What stands out about Alcoa’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
Shortly after the Pittsburgh Reduction Company changed its name to the Aluminum Company of America in 1907, the company began investigating the possibility of establishing a large smelting operation in East Tennessee. The hydroelectric potential of the Little Tennessee River, which exits the mountains about 20 miles (32 km) southwest of Alcoa, was one of the primary incentives, as the company's aluminum smelting operation would require massive amounts of electricity. In 1910, the company established a base camp at what is now known as Calderwood, initially known as "Alcoa", and was known as such until the name was reapplied to the company's operations in North Maryville a few years later.
