The English Wikipedia happens to be the most edited in West Africa and is edited in all 18 countries with Nigeria and Ghana having [30-40] and [110-120] "active contributors” respectively, every other country has [0-10] number of Engligh language countributors. For other languages besides English, there are [0-10] number of contributors if they exist at all in any of the 18 West African countries. Interestingly, Senegalese contributors edit 10 different Wikipedia's; this is followed by Mali and Benin contributing to 9 Wikipedias and Cote D'Ivoire 8. All four countries are francophone.

My take on the data
The three officially recognized User groups in the region appear to be doing relatively better than the rest. Another country that is doing well but not yet a user group (and should be looked out for), is Benin. Considering their small population, they have an equal number of “active” editors as Ghana and on top of that they surpass us in number of “very active” contributors. Also, I’m personally surprise to see contributors to languages other than English, French, and Arabic in the region. Languages such as Esperanto, Hebrew, Far Eastern, and Turkish made it into the list, some of them “very active” editors. I'm curious to learn more about who these editors are. In all, no single country seem to have stood out in any big way, maybe we may need to investigate more data from the past or even looking forward into the future to see how these numbers would behave.
