Ancestry Predicts Surname Socioeconomic Standing

Using 31.6 million scraped administrative and genetic‑test records mapped to ~11,000 U.S. surnames, ancestry proportions from 23andMe pages predict a composite surname socioeconomic score (salaries, occupational prestige, physician licensure, criminal representation) with cross‑validated correlation r ≈ 0.899. The result is robust across modeling approaches and appears driven in part by selective migration, testing uptake, and how surnames traverse populations. — If replicable, this finding reframes debates about the explanatory power of ancestry data (social vs. biological), informs immigration and inequality narratives, and raises privacy and misuse risks from surname‑level genetic inferences.
