I can say that the estimate for Senegal (specifically for Dakar) is rather accurate if you want to live by Western standards/sense of comfort. I was born and raised there until end of high school then have been living in Europe for 10 years (but going back home every summer for the holidays), and I noticed this year that the prices in the capital are quite similar to the ones I have in Brussels right now (which is totally crazy given that the minimum wage is around 100€/month).
