What is the African nuclear family?

A nuclear family is always a universal term. The term applies universally to families fulfilling certain criteria, based on the atomic model of a nucleus orbited by electrons. In the Nuclear Family model, the parents form the nucleus (there must be two), and then the children form the outside surrounding the parents. A standard number in an MEDC would be three, but in an LEDC like most in Africa, nine or ten would not be uncommon.
