::Iseebias's edit (descriptive paragraph instead of a table) is an improvement, mostly because it is less specific. However, it still includes only 3 or 4 of the possible interpretations of who is Black, and the numbers are a little soft (I enjoyed reading the source, however, it appears a little wacky). In the end, an article about a social group in one country could make some attempt at definition to use for a count (census definition in the US, perhaps trickier elsewhere). For this article, however, we have social constructs in 200 countries, many of which are not legally defined, many of which use words other than "Black" which we are taking the liberty of assuming mean "Black." There is no way under these circumstances to have anything approaching sourced population estimates.  
 ::One could get the number of sub-Saharan Black Africans, and put that in an article on sub-Saharan Black Africans. But that is not the article we have. I'd happily merge the content from here into several specific articles, and then put this up for deletion, but that's already been tried. So it is going to stay, but that makes including any population estimates a mess. Even the improved paragraph should go.
