On an extremely tangential note: I wish we would stop using the term, "Sub-Saharan." The semantic quandaries should be obvious, but it also subscribes to a curious linguistic glitch of putting the North and South into a hierarchy that only exists if you are rather incurious about the ambiguity of geographic perspective (see: the infamous "upside down" Gall-Peters projection for some mind-blowey fun). I would personally prefer something like "SOS (South-of-Sahara) Africa," or perhaps even something as provocative as "Africa Major" (riffing on Asia Minor and referring to the fact that that part of the continent is, in fact, a majority of its landmass).
