Method notes

Census treats race and Hispanic/Latino origin as separate questions. Race categories other than Hispanic reflect total populations (small Hispanic overlap in Black, Asian, AIAN, NHPI). “Multiracial / Other” is derived as a non-overlapping remainder.

Black / African American (estimated remainder) is derived as Black population share minus reported Sub-Saharan African and West Indian ancestry. It is shown as an estimated ancestry detail, not a standalone Census ancestry category.
