I agree with some of the post about it is a way of investment and also if they have more children there is more posibility that one or more of them will survive.
But you forgot about the gender roles. Well, i'm not nigerian, but i've been reading about this topyc in other countries such an India (Vandana Shiva, Maria Mies), Marocco, China, I know there are cultural differences, but maybe it's general to developing countries. In demography they call it "Demographical transition", passing for a kind of society to another.
For example, it changed in Spain after the baby boom of the decade of 1960 in the 70's women star figthing for their rights and joining the employment market, so that's why we women started using condoms or other anticonceptibs and also starting to have children later, or to have less children becausa we couldnt spend all the day looking for 5 or more children like before working for earning a salary.
So maybe, in a country like Nigeria, middle class families had start sending women to school and they've start joining the job market, while in poor and rural families they still have the role of taking care of the family and not working outside home, that's why they have more children.
A few international agencies have try to solve this problem just giving condoms, but it won´t work without changing the culture and the women role.
Another problem is that some chemist international companyes are using poor women from developing countries to make experiment on anticonceptive pills, or sterilize them without their permision.

Thanks for your advices. I've talked to him and now i understand everything. I'm sorry if i've ofended someone, it was not my intention.
I will love (gnayna) him as well if he have told me he is in the mafia, but i'm glad it doesn´t exist. So lets continue learning how a relationship works with a Nigerian.

Let me explain. Im sociologist and interested in antropology. I speak spanish, catalan and basque, two other regional languages in Spain. I love Igbo and im trying to learn a little bit of it. Its just a month that i knew such a culture exist, so im interested. Thats why im writing in this nigerian web site, because he likes it, and i've just asked a silly question, because i like joking with him.
Thanks for your answers.

Well, im happier now that i know that igbo mafia doesnt exist. but im still trying to understand what he is into,

Hi,

I'm from Bilbao, a city in Spain and i'm dating an igbo man. He is very nice with me, but he is allways talking to his friends on the phone on igbo and i understand nothing, but they allways talk about money. Is he the godfather of a kind of igbo mafia group?
