SourceSupplemental Data for Micheletti et al. (2020)The labeling for B & D is reflecting the initial names for categories which are now shown as resp. “Ghanaian, Liberian & Sierra Leonean” and “Angolan & Congolese”. Obviously only meant to be indicative! However again most likely no coincidence that “Nigerian” is showing higher concentrations in the Chesapeake area as well as extensive areas in the Deep South which were on the receiving end of Domestic Slave Trade. Perhaps even more tellingly South Carolina seems to be the main hot spot for the other three regions. Especially “Congolese”. Interestingly Senegambian & Guinean” seems to have a second focal point in Louisiana.

This overview is showing the scaled African breakdown for the combined USA sample group (n=5785) featured in Micheletti et al. (2020). As well as seven broader regions within the USA as defined by 23andme’s researchteam (see this overview). The data has been sorted on highest to lowest group average for “Nigerian”. Despite some minor variation overall speaking quite similar proportions for each region. However it is most likely no coincidence that “Nigerian” is peaking for Chesapeake and East Inland (KY, TN). As this would be in line with Virginia and surrounding states having a more pronounced Bight of Biafra connection. Do notice also that South Atlantic (which includes South Carolina) has a somewhat higher group average for “Ghanaian, Liberian & Sierra Leonean” as well as for “Angolan & Congolese”.
