The Hutterites are notable for a few other reasons, too. They have been the subject of genetic studies because they marry and have children within small communities and keep excellent genealogical records. To the degree that there is a small genetic pool, problems can arise and various genetic diseases and conditions can be studied, contributing to our genetic knowledge. They are also pacifists, very strongly so, and had to leave many countries because of this, subject to a great deal of prejudice because of it in the United States, too.
Hutterites live mostly in Canada. They speak German and are similar to American Amish in that they avoid the modern world as much as possible. They live in colonies and observe strict religious rules. There are some Hutterites in North and South Dakota and Minnesota.
