The 1910 special U.S. census of American Indians, overseen by Harvard anthropologist Roland Dixon, reported that mixed-blood Indians were increasing much faster than full-blood Indians and concluded that, unless conditions changed, full-blood Indians would eventually disappear altogether.
Notes on verification
Multiple independent scholarly and reference sources corroborate the 1910 special census details, Dixon's role, and its conclusions about mixed-blood vs full-blood population trends. [cascade flags: wikipedia_dropped_other_sources_exist | tier=silver indep_score=0.838 clusters=4 claim_tier=notable]
