How many immediate family members are there? How many generations famailies are allowed? How are families decided?

There are four immediate family members. A mother, father, and two children (one boy and one girl). Spouses are chosen by the government and children are placed accordingly.

     The child comes when a family unit receives there childs number. The family unit can only have one male, one female as there spouses. The community does not allow adults to choose their "mates".
