Of those coming to America, only 443 chose to live communally, initially in South Dakota. Contact with the others has been lost. Each colony in the new world today has 60 to 160 people. Hutterites have very large families with the average couple having nine to ten children. Divorce is unheard of.
Men stay with the colony after marriage while the women move to the colony of their husbands.
Hutterites are opposed to contraception. The average colony has between 15 and 45 adults. Once a colony grows to 150 members or so, the colony develops a second colony. After it is built, all families draw straws or match up with their preferred preacher on an equitable basis and the two preachers draw straws to see which families move to the new colony. The wealth of the origin colony divided in half so that each of the two new communities gets an equal share.
