History grade
What drives Beaumont’s History grade
On its age, its old homes and the National Register, Beaumont is more historic than 19% of U.S. towns, #488 of 847 in California. Its age holds the grade up; its share of homes from before 1940 pulls it down.
C−
HistoryA character grade: shown, never part of Beaumont’s overall grade.
Few California towns list much on the Register (a typical California town has 0.0 per 10,000 residents, the U.S. 2.4), so Beaumont’s 0.0 sits below most of its state (31% of California 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 (±1.1 points) is firm at this size. The founding year is the first post office, not a stated founding date.
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.

Beaumont, which is French for "Beautiful Mountain", received its name in 1887 from Henry C. Sigler, president of the Southern California Investment Company, because Mount San Jacinto is nearby and visible from the city.
