In 2000, according to the U.S. Census, there were 220,657 American Indians living in California, for those designating only one race, and excluding Alaska Natives and Native Hawaiians in California. California had the second-largest Native American population of any state, second only to Oklahoma.
Most of the American Indians in California are native California Indians, while many other Indians have come from other states either through relocation by the United States government or for employment purposes. There are over 100 federally-recognized Indian tribes in California, and almost 100 Federal Indian reservations in the state, with about 40 Indian groups seeking to gain federal recognition.
Prior to the arrival of the Europeans, the native peoples of California lived in all areas of the state. There was no "empty" land, as long as that land could support human life. Nowhere else in the United States is there such a variety of cultures and languages spoken.
California Indians have dozens of languages and dialects from six major language families: Hokan, Penutian, Algonkian, Athabascan, Uto-Aztecan (Shoshonean), and Yukian.
