Tl;dr Demographers have previously assumed that since Asia followed the same path, the European model of demographic transition was a universal truth. However they underestimated the impact of cultures (in Africa having large families is considered has an assurance as if one of the children succeed the parents will be protected), religion (in Islam even if contraception is legal, one need a valid reason and procreation is heavily encouraged), traditions, genetic differences (I think I read somewhere the age of puberty is a bit lower for people of West African descent) etc. A documentary about this phenomenon in Niger: https://youtu.be/btMUecYNBc4 https://youtu.be/btMUecYNBc4
