This appendix presents some facts and figures about the families who participated in our project, including the number of wives in plural families, age of marriage of husbands and wives, sororal marriages (sisters married to the same husband), number of children in families, divorce rates, and men's and women's occupations. We also present comparative data for 19th-century Mormon plural families.

These seemingly straightforward demographic topics are more difficult to study than meets the eye – and for different reasons for the pioneer and contemporary eras of Mormon polygyny. For example, we found no published demographic analyses of present-day groups. Elders of the groups with whom we worked said that detailed demographic records are not maintained. Furthermore, our sample of families is quite small and is not randomly selected or representative of the total population of families in fundamentalist groups. What we present, therefore, is based on a combination of estimates by contemporary scholars and observers, our discussions with fundamentalist leaders, and information from the families with whom we worked. The complete facts are also not available for 19th-century Mormons. Records of marriages, births, and divorces were not always kept or were incomplete during the pioneer era, especially because of attempts to maintain secrecy about plural marriages. Once the Mormons settled in Utah in 1847, and prior to the Manifesto of 1890, good records were maintained. Before and after that period, however, the data are less comprehensive.
