Subgroup detail: B03001 (Hispanic or Latino specific origin), B02015 (Asian groups), B02020 · B02016 (American Indian/Alaska Native tribes and Pacific Islander groups), B04006 (reported ancestry). Hispanic/Latino is an ethnicity that overlaps the race categories, so group shares can total more than 100%. All subgroup rows are shares of total population; ancestry is self-reported and multiple-response, so rows do not sum to the parent group's share.
