I think this colouration is changing and I have heard more people, people of less classes in the society discuss the need to bear few children and the singles too are having change of mind. To prove that the numbers are beginning to reduce, if you go to African wedding especially that of Nigeria, during the reception when the MC ask the celebrants how many children they would like to have, they usually say 2 to 4 children especially 3/4 children and not up to 5 except on rare occasions where they would say the 5th may be the one of " mistake ".

So I think education is what has caused this paradigm shift. More lower class people are getting educated lately and they are being knowledgeable and also trying to lessen the burden of training plenty children to fewer children and having comfort and living a comfortable live for themselves and children. All of those where never in the picture in the past as they never matter in the scheme of things in the old days. There is shift in the way things are done now in terms of family live.
