Indian Americans are Americans whose ancestry originates wholly or partly from India. The terms Asian Indian and East Indian are used to avoid confusion with Native Americans in the United States, who are also referred to as "Indians" or "American Indians". With a population of more than 5.4 million, Indian Americans make up approximately 1.6% of the U.S. population and are the largest group of South Asian Americans, the largest Asian-alone group, and the second-largest group of Asian Americans after Chinese Americans. The United States hosts the largest Indian diaspora by population, though not by percentage.
