On its age, its old homes and the National Register, Oxnard is more historic than 48% of U.S. towns, #162 of 847 in California. Its National Register listings hold the grade up; its share of homes from before 1940 pulls it down.
B−
HistoryA character grade: shown, never part of Oxnard’s overall grade.
Among the 400 U.S. cities of 100,000 or more, Oxnard ranks #248 on History.
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 Oxnard’s 7.3 sits above most of its state (90% of California towns have fewer) while its 147 historic buildings outnumber those of 92% of U.S. towns.
Newer cities are common at Oxnard’s size: in the typical U.S. city of 100,000 or more, 5% of homes predate 1940.

Before the arrival of Europeans, the area was inhabited by Chumash Native Americans. The first European to encounter the area was explorer João Rodrigues Cabrilho, who claimed it for Spain in 1542. During the mission period, Mission San Buenaventura, established in 1782, used the area for raising cattle.
Ranching began to take hold among Californio settlers, who lost their regional influence when California became a US state in 1850. At about the same time, the area was settled by American farmers, who cultivated barley and lima beans.
