Hmm. Since urban life is more prosperous and wealthier - how big would the Yoruba/Duala percentage be? Would they constitute maybe 25% of the total population? 45%?

I'd suspect they won't be much different than IRL. The Duala aren't a big group, but they are well placed, so you're looking at maybe a half million people there. The Yoruba are a pretty big group, 20% of Nigeria, which at this point should mean eight million.
