What drives Alhambra’s History grade
On its age, its old homes and the National Register, Alhambra is more historic than 61% of U.S. towns, #94 of 847 in California. Its share of homes from before 1940 holds the grade up; its age 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 Alhambra’s 0.1 sits near the middle of its state (64% of California towns have fewer) while its 1 listings outnumber those of 51% of U.S. towns.
