HistoryA character grade: shown, never part of Azusa’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 Azusa’s 0.4 sits above most of its state (69% of California towns have fewer) while its 2 historic buildings outnumber those of 60% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from C− to B−. The pre-1940 share (±1.2 points) is firm at this size.

The name "Azusa" appears to have been derived from the Tongva place name Asuksa-nga, meaning "skunk place," with asuksa meaning skunk and -nga denoting place.
The first human settlements in the area date back to approximately 6000 BC. The Takic people moved into the area c. 3500 BC and the Tongva people (Gabrieleño Indians), now commonly regarded as the indigenous people of the region, arrived by at least 55 BC. A backronym, "Azusa stands for everything from A to Z in the U.S.A.", has been a phrase used for many years by organizations such as the Chamber of Commerce to promote the city.
