The 1900 Indian schedule asked only about "white blood" (United States, 1900)

SUMMARY5. The 1900 Indian schedule asked only about "white blood" (United States, 1900) [Connections: Who decided who's Indian, Nov 5, 2026]

RECORDThe special Indian schedule (Form 7-464) had columns "Tribe of this Indian," "Tribe of Father," "Tribe of Mother," and "Has this Indian any white blood; if so, how much? (0, ½, ¼, etc.)," plus "Is this Indian taxed?" and "Was citizenship acquired by allotment?" There was no column for African ancestry. The general instructions defined "B" as "black (negro or of negro descent)." Paragraph 249: "Detached whites or negroes living in Indian families are also to be enumerated on this special form … but detached Indians living either in white or negro families outside of reservations are to be enumerated on the general population schedule (Form 7-224) as members of the families in which they are found."

PATTERNThe Indian form could record a white parent but not a Black one; "of negro descent" made you "B" on the general form. An Indian living in a Black household off-reservation was moved to the general schedule with that household

LENS (WW9)The Indian page had a door for white blood and none for Black; mixed Aboriginal-Black families were sent to the "B" page

OPENParagraph 249 governs which schedule, not the color mark; check sample general schedules for whether such persons got "In" or "B."
