A1: As an encyclopedia, Wikipedia content is based on reliable sources (see Wikipedia:Verifiability, Wikipedia:Reliable sources). Many reliable sources over a long period of time refer to Harris as African American and Asian American, so we reflect that in this article. Moreover, Harris's Senate and campaign websites state that she is African American and Asian American. In addition to describing Harris's African American and South Asian American background, this article also recounts the origins of Harris' mother (Indian) and father (Jamaican).

As PolitiFact notes (see A look at Kamala Harris' multi-ethnic background and racial identity in the US, PolitiFact (August 14, 2020)), social media posts have inaccurately suggested that Harris cannot be African American because she has an Indian mother and Jamaican father, but "this is a poor understanding of history, and ... the implication that Jamaicans aren't African or connected to Africa is wrong on its face." While not all Jamaican-Americans identify as "African-American," Harris and many others do.
When Wikipedia describes Harris as the "first" to do something, we default to the larger category. Therefore, she isn't the first Tamil-, Indian-, or South Asian-American to be elected Vice President of the US (although she is all of those things); instead we note, as reliable sources do, that she's the first Asian-American.

Also of note is the difference between race and ethnicity. Race is grouping based on society's view. Ethnicity is grouping based on how people see themselves in common with others. Ms. Harris's race is unimportant. Her ethnicity is paramount. Using this criteria, Ms. Harris is clearly African-American and South Asian-American.
