Question: which countries are not in sub saharan africa?
Answer: The UN Development Program lists 46 of Africa's 54 countries as “sub-Saharan,” excluding Algeria, Djibouti, Egypt, Libya, Morocco, Somalia, Sudan and Tunisia. This doesn't make geographical sense—four countries included are on the Sahara, while Eritrea is deemed “sub-Saharan” but its southern neighbor Djibouti isn't.
