The power of Western agency means that they can construct words which speak exclusively to their perceived reality. The UN, EU, World Bank, IMF or any other big institution that you might think of has been leading in using the term SSA. It must be pointed out that even many governments and organizations in this region also use the term SSA without really interrogating the meaning or implied meaning of SSA. This has been useful in setting up a false dichotomy and systematic normalization of the term.It is important to emphasize that these deeply embedded assumptions and stereotypes about Africa not only stand in the way of effectively learning about the continent, but also have been the basis of ill-conceived academic research and policies.
