The U.S. Census Bureau definition includes those who originate from the original peoples of Southeast Asia and the Indian subcontinent. In 1930 and 1940, Indian Americans were identified as a separate race, Hindu, and in 1950 and 1960 they were racially classified as Other Race, and then in 1970 they were classified as White. Since 1980, Indians and all other South Asians have been classified as part of the Asian race. Sociologist Madhulika Khandelwal described how "....as a result of activism, South Asians came to be included as 'Asians' in the census only in the 80's. Prior to that many South Asians had been checking 'Caucasian' or 'Other'."
Respondents can also report their specific ancestry, e.g.: Okinawan, etc. Someone reporting these ancestries but no race would be classified as "Asian". Unlike South Asians, Middle Eastern Americans and Central Asian Americans have not lobbied to be included as Asians by the U.S. Census Board.
According to Sharon M. Lee in her 1998 publication, for many non-Asian Americans in the United States (in 1998), "Asian American means Oriental, Chinese American or Japanese American. This is due to the Chinese and Japanese immigrants being the first Asian immigrants into the United States. Today, with the increasing demographic of South Asian Americans and Southeast Asian Americans the definition among United States citizens of who is Asian American is expanding."
