The family is the foundational unit of their society. A family group ordinarily consists of three generations with between 10 and 16 persons, not counting their children. The senior male member is head of the family.
The population of each city is maintained at about 6,000, and in the event of a marked rise in the birthrate, some families are sent to other cities where they can be accommodated. If the population of the entire country exceeds their prescribed norms, some are sent as colonists to other countries that are not so densely populated.
