Asian Americans are Americans of Asian ancestry. Although this term had historically been used for all the indigenous peoples of the continent of Asia, the usage of the term "Asian" by the United States Census Bureau only includes people with origins or ancestry from the Far East, Southeast Asia, and the Indian subcontinent and excludes people with ethnic origins in certain parts of Asia, including West Asia who are now categorized as Middle Eastern Americans. Furthermore, Central Asians are not mentioned in any census racial category. The "Asian" census category includes people who indicate their race(s) on the census as "Asian" or reported entries such as "Chinese, Indian, Bangladeshi, Filipino, Vietnamese, Indonesian, Korean, Japanese, Pakistani, Malaysian, and Other Asian". In 2020, Americans who identified as Asian alone (19,886,049) or in combination with other races (4,114,949) made up 7.2% of the U.S. population.

Indian Americans are citizens of the United States with ancestry 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 4.9 million, Indian Americans make up approximately 1.35% of the U.S. population and are the largest group of South Asian Americans, the largest Asian-alone group, and the largest group of Asian Americans after Chinese Americans. Indian Americans are the highest-earning ethnic group in the United States.
