The Demography of Colony Fission from 1878–1970 Among the Hutterites of North America

Periodic colony fision has been characteristic ofHutterite society for more than 100 years. From 1878–1970 fission occurred an average of every 14–15 years when colonies attained a size of 166 persons. Emigrating groups were comprised of35%–55% of the mother colony's population. Between founding and fission, daughter populations grew at an average rate of 4.3% per year. Over time, fissioning size and length of fission cycles decreased, but the size of new daughter colonies and rate of population growth remained constant through 1960. Demographic analysis suggested that the model of fission followed by the Hutterites has not always focused on even division of the mother colony into two equal‐sized groups, but rather that they have had a fairly constant conceptual model of the size that new colonies should be. As fissioning size decreased over time the proportionate size of new colonies increased, maintaining the absolute size nearly constant since 1900. These findings suggest a number of questions for further investigation.
