Population History of the Onondaga and Oneida Iroquois, A.D. 1500–1700

Much of the discussion about North American precontact and contact-period populations has focused on continent-wide estimates. Although the associated work has produced valuable information on the demographic and cultural history of the continent, it has failed to generate agreed-upon estimates, population trends, or detailed demographic knowledge of Native American cultures. Using archaeological settlement remains and methods developed in recent research on Iroquoian cultures, this study estimates and examines population trends for the Onondaga and Oneida cultures of the Haudenosaunee (Iroquois) from A.D. 1500 to 1700. Onondaga population appears to have increased until the mid—seventeenth century, when drastic declines in settlement area and population size occurred. This depopulation event is both several decades after first contact with Europeans and at least a decade after the first known depopulation event among the Haudenosaunee. Oneida populations show a much more complex history that suggests the need for more detailed analyses of contact-period Native American population data. In conjunction with archaeological evidence and ethnohistoric information, the population trends generated by this study create a model of two precontact Native American populations and display the effects of European contact on those populations.
