In Prout Village, there is no marriage certificate, and the concept of marriage has been eliminated. It is up to the couple to decide if they want to have children. It is possible for couples to use different surnames, and at present, children will take the surname of either of their parents. However, they are free to decide whether or not to use the form of marriage for religious reasons or their parents' wishes. In this way, even at an advanced age, people can easily date and break up with someone.

The basic rule is that people raise their children on their own, but since all residents have time to spare, they can afford to help each other raise their children. Once the child is born, the parents' names and the child's name are registered with the local government.

In Prout Village, women can give birth in their teens while they are still strong enough to do so, and there is no need to worry about medical expenses or the cost of education no matter how many children they have. At Prout Village, you can have children regardless of your financial ability, and you don't have to worry about their later life.

This is the basis for sex education in the home or in the local government. For this reason, the medical and food departments should prepare materials that can be explained on the Internet or in books at any time.
