More historic than 19% of U.S. towns, on its age, its old homes and the National Register.
On its age, its old homes and the National Register, Anderson is more historic than 19% of U.S. towns, #503 of 847 in California. Its age holds the grade up; its share of homes from before 1940 pulls it down.
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 Anderson’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.
Founding year: the first post office (other dates in Quick answers). Homes: Census ACS 2020–24.
