Dramatic differences emerge between Nauvoo and contemporary cities and counties in Illinois, Missouri, Ohio and the Territory of Iowa. In each of these other frontiers there existed a dominant single male population, whose ages ranged from 20-30 in the 1840s. For these young men it appears that the lands bordering the Indian Territory were not conducive to family life. They migrated from villages, towns, and cities throughout the United States, with only a few migrating from Europe. They came with the hope of taming the wilderness and obtaining personal fortune.
In contrast, the early settlers of Nauvoo consisted of an equally balanced male and female population. Their age groupings included not only the young adults, but the elderly and the young children who migrated to Nauvoo in extended family clusters.- "New Insights Replace Old Traditions: Membership of the Church in Nauvoo, 1839-1846," Susan Easton Black, associate professor of Church History and Doctrine, BYU
