Don’t think numbers are entirely accurate but what it’s trying to portray is.
No sub-Saharan African countries at the top of the list. North Africans do tahriib like crazy how gaajo must their countries be. Albanians having a 1 mill diaspora to 2 mill population will finish them too, they’ll get eaten up in the future.
Separately, I think the Somali total diaspora in Europe is around 550-600k.
