  1. ACB, African Caribbean in Barbados; ASW, people with African Ancestry in Southwest USA; CEU, Utah residents with Northern and Western European ancestry; CLM, Colombians from Medellin, Colombia; FIN, Finnish in Finland; MXL, Mexican ancestry from Los Angeles; Nat. Am., Native American; PUR, Puerto Rican.
  2. Rows are grouped to coincide with the discussion. Admixture statistics are expressed as d>x, Pin%, Pout%, meaning that Pin% individuals assigned to the cluster and Pout% outside the cluster have estimated admixture proportions for ancestral population d>x. The ‘1000 Genomes’ column summarizes population labels of any 1000 Genomes samples that project onto the same stable subsets defined in spectral embedding (Fig. 6; Supplementary Figs 4,5). See Supplementary Data 2 for a more detailed summary of the clustering results, including definition of the population labels (d).
  3. *A stable subset including more than 5% of a hierarchical cluster.
  4. A hierarchical cluster in which no detected stable subset includes more than 5% of the cluster.
  5. Interpretation of cluster is uncertain; label represents our best estimate.
  6. §Dominicans cluster is contained within Caribbean cluster.
  7. Not shown in Fig. 3.
  8. A stable subset accounting for less than 5% of a hierarchical cluster.
