770 thousands genomes reveals post-colonial population structure of North America

In the study, the researchers identified "genetic communities" throughout North America using data from more than 774,516 people born or currently living in the United States. The map below shows the distribution of ancestral birth locations associated with these "communities".


The distribution of ancestral birth locations
Clustering of 770,000 genomes reveals post-colonial population structure of North America.
Points show pedigree birth locations that are disproportionately assigned to each cluster. Only birth locations with OR>x within indicated generations y–z are plotted, in which parameters x, y, z are chosen separately per cluster to better visualize the cluster's historical geographic concentration. For each cluster, points are independently scaled by the number of pedigree annotations /Nature/.
