From the author: A church book containing vital information on Dariusleut Hutterite families enabled us to trace the life course of individual women. We conducted a retrospective cohort study on the women born in the Dariusleut sect for the period 1901-1965, focusing on their marriage and reproductive histories. The subjects were grouped into 5-year birth cohorts from 1901-1905 to 1961-1965. The marital age-specific fertility rate (MASFR) increased from the 1901-1905 cohort to the 1926-1930 cohort and then began to decrease, particularly at the ages of 30-39 years. The initial increase in MASFR was not reflected directly in the cohort mean of the total number of children per woman because of a concurrent delay in age at marriage. Marriage delay, however, could not explain the drastic decrease, which started in the 1931-35 cohort, in the total number of children per woman; the decrease in MASFR at the ages of 30 years and older was considered a major reason for the recent changes in Hutterite fertility. The causes of the recent fertility decrease of Hutterites at higher ages remain to be investigated.

The second edition of the “International Encyclopedia of Marriage and Family” adopts an international, cross-cultural approach to such diverse and important topics as adolescent parenthood, family planning, cohabitation, widowhood, domestic violence, child abuse and neglect, codependency and commuter marriages. It includes articles specific to countries and to religious traditions, examining the history of family life within these cultures and discussing how families have been affected by political and social change.

From the author: We present a Monte Carlo method for determining the distribution of founders' genetic contributions to descendant cohorts. The simulation of genes through known pedigrees generates the probability distributions of contributed genes in recent cohorts of descendants, their means, and their variances. Genealogical data from three populations are analyzed: the Hutterite population of North America, the island population of Sottunga from the [angstrom]land archipelago, and the large Utah Mormon population. Two applications of the Monte Carlo method are presented. First we investigate the relative opportunity for founder effect in the three populations, which have dissimilar pedigree structures and dissimilar disease gene frequencies. Second, we measure the reproductive success of population founders in terms of the number of genes they contribute to a cohort some number of generations descendant and compare the effects of polygyny versus monogamy on reproductive success. The distribution of Hutterite founder contributions describes the context for a classic founder effect. Hutterite founders have a higher probability of leaving no genes in the population (72%) than Sottunga (48%) and Mormon (48%) founders. However, founder genes that survive among Hutterite descendants do so in larger numbers on average than founder genes in the other two populations. Greater variation among monogamous Hutterite founders compared with Mormon polygynous founders demonstrates that polygyny alone does not maximize the variance in reproductive success; other population characteristics are at least as important for determining variability among individuals in their genetic contributions to a gene pool. Our findings make it difficult to appreciate the reproductive advantage of polygyny in the Mormon population. Although the expected gene contributions and their variances were larger for polygynous founders compared with other Mormons, the main effect of polygyny was to increase the probability that any polygynist left a few genes among descendants. Furthermore, only 12% of the variation in the genetic contributions of Mormon founders is explained by their number of offspring. We conclude that shallow genealogical data (from one or a few generations) provide a poor measure of long-term reproductive success.

From the author: A church book that has been routinely updated by the Dariusleut Hutterites enabled us to update some fertility tables presented by Eaton and Mayer in the 1950s. The age-specific (nuptial) fertility rates and the total fertility rates (TFRs) were calculated for every 5-year period from 1901-1905 to 1981-1985. Our calculations for Dariusleut, one of the three sects of the Hutterites, gave slightly lower age-specific nuptial fertility rates before 1951 compared with the figures given by Eaton and Mayer (1953) for all Hutterites in the corresponding time periods. The recent decline in Hutterite fertility, especially at higher maternal ages, was confirmed in this study. The TFR, given as a sum of 5-year-grouped age-specific nuptial fertility rates from 15 to 49 years of maternal age, was higher (8.80-9.83) in the years 1946-1965, but it declined to 8.13 in 1966-1970, to 7.22 in 1971-1975, to 6.39 in 1976-1980, and to 6.29 in 1981-1985. For the age groups 35-39 years and older the age-specific nuptial fertility rate in 1981-1985 decreased by more than 50% compared with the rate during the peak period of 1951-1955. The probability of a married woman having a live birth at each age from 15 to 49 years still peaked around the twentieth year of life, as found by Eaton and Mayer (1953), but it decreased more rapidly from the late twenties among the recently married women, most evidently in their thirties.
