Native Americans in the United States

In the United States, Native Americans are considered to be people whose pre-Columbian ancestors were indigenous to the lands within the nation's modern boundaries. These peoples were composed of numerous distinct tribes, bands, and ethnic groups, and many of these groups survive intact today as sovereign nations. The terms Native Americans use to refer to themselves vary regionally and generationally, with many older Native Americans self-identifying as "Indians" or "American Indians", while younger Native Americans often identify as "Indigenous". Which terms should be used to refer to Native Americans has at times been controversial. The term "Native American" has been adopted by major newspapers and some academic groups, but has not traditionally included Native Hawaiians or certain Alaskan Natives, such as Aleut, Yup'ik, or Inuit peoples. Indigenous American peoples from Canada are known as First Nations.

Since the end of the 15th century, the migration of Europeans to the Americas has led to centuries of exchange and adjustment between Old and New World societies. Most Native American groups had historically lived as hunter-gatherer societies and preserved their histories by oral traditions and artwork, which has resulted in the first written sources on the conflict being authored by Europeans.

Race and ethnicity in the United States Census

Race and ethnicity in the United States Census, defined by the federal Office of Management and Budget (OMB) and the United States Census Bureau, are self-identification data items in which residents choose the race or races with which they most closely identify, and indicate whether or not they are of Hispanic or Latino origin (the only categories for ethnicity).

The racial categories represent a social-political construct for the race or races that respondents consider themselves to be and "generally reflect a social definition of race recognized in this country." OMB defines the concept of race as outlined for the U.S. Census as not "scientific or anthropological" and takes into account "social and cultural characteristics as well as ancestry", using "appropriate scientific methodologies" that are not "primarily biological or genetic in reference." The race categories include both racial and national-origin groups.

Race and ethnicity are considered separate and distinct identities, with Hispanic or Latino origin asked as a separate question. Thus, in addition to their race or races, all respondents are categorized by membership in one of two ethnic categories, which are "Hispanic or Latino" and "Not Hispanic or Latino". However, the practice of separating "race" and "ethnicity" as different categories has been criticized both by the American Anthropological Association and members of U.S. Commission on Civil Rights.
