Resumen:
Indigenous populations all over the world are experiencing dramatic lifestyle changes that have serious consequences for their population structure. Evidence is accumulating, particularly in small-scale societies living in tropical regions, that points to synergistic interactions among socio-economic, historical, and cultural agents and their effect on the demographic, nutritional, and epidemiological composition of a group, which in turn feeds back to demographic patterns to portrait a dynamic picture of population change. Most of these native communities are adopting “western” lifestyles as the inevitable product of the contact with industrialized, market-economy hegemonic cultures. This process of “Westernization” is characterized by the abandonment of traditional ways of life, including a shift in subsistence practices from hunting and gathering to purchasing goods in local markets, an increase in urbanization and secularization, and an increase in individualism, marked by an increased emphasis on education. Argentina’s indigenous population is not the exception to this worldwide trend. Lowland indigenous groups in Argentina can now be found along an acculturation gradient, ranging from a rural, more traditional lifestyle that is relatively dependent foraging, to an urban, sedentary lifestyle that relies on wage labor and store-bought goods for sustenance. Virtually no studies have been conducted that focus on the effect that these dramatic changes in their environment (both physical and social) are exerting on the demography of Argentine native populations. The aim of this work is to present an analysis of fertility patterns in a Toba population, one of several indigenous groups currently living in the Gran Chaco region in northern Argentina. We will discuss possible proximate mechanisms underlying the observed patterns and suggest useful approaches for future research and issues that deserve closer attention.
