More historic than 5% of U.S. towns, on its age, its old homes and the National Register.
On its age, its old homes and the National Register, Centerville is more historic than 5% of U.S. towns. Its National Register listings hold 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 Centerville’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.
