Native Americans are Indigenous peoples, the only nonimmigrant people in the United States. According to the National Congress of American Indians, Native Americans are “All Native people of the United States and its trust territories (i.e., American Indians, Alaska Natives, Native Hawaiians, Chamorros, and American Samoans), as well as persons from Canadian First Nations and Indigenous communities in Mexico and Central and South America who are U.S. residents.” Native Americans once numbered in the millions but by 2010 made up only 0.9 percent of U.S. populace; see above (U.S. Census 2010). Currently, about 2.9 million people identify themselves as Native American alone, while an additional 2.3 million identify themselves as Native American mixed with another ethnic group.
