Language maps of the US, include African languages

So, this is interesting. Slate has as series of interesting maps showing the most popular languages spoken in each American state. After filtering for the obvious second language (Spanish), they present a series of specialized maps, including the most popular African language in each state. Data probably is not perfect, but likely about as good as we have. “Kru, Ibo, Yoruba” seems to be most dominant (Go, Nigeria and West Africa!). After that is Amharic and Cushite. Then Swahili, Bantu, and “Nilotic” (Sudanese mostly?).
