Son-preference is an important feature of patriarchal societies. Assume tha in such a society there is a 50% chance of having a boy and 50% chance of having a girl for each birth. Assume that there are 16 couples. Each couple keeps trying to have a boy. If a girl is born, they try again until a boy is born. Then they stop. What will be approximately the total number of boys and girls in this scenario? Does the boy-girl ratio change?
