POPULATION STRUCTURE AND DYNAMIC OF HUNTER-GATHERERS FROM THE MÉDANO PETROQUÍMICA SITE (LA PAMPA, ARGENTINA): INFERENCES FROM LIFE TABLES AND OTHER PALEODEMOGRAPHIC INDICATORS
ESTRUCTURA Y DINÁMICA POBLACIONAL DE LOS CAZADORES-RECOLECTORES DEL SITIO MÉDANO PETROQUÍMICA (LA PAMPA, ARGENTINA): INFERENCIAS A PARTIR DEL USO DE TABLAS DE VIDA Y OTROS INDICADORES PALEODEMOGRÁFICOS

Paleodemography is a line of research that is often underestimated in bioarchaeological studies because prehistoric sites generally lack written records that provide accurate information about the societies that generated them. Given the high number of individuals buried at the Médano Petroquímica site and the short period of occupation thereof, the use of life tables and different paleodemographic indices would allow us to provide relevant information about population dynamics for the study area during the late Holocene. Infant mortality, female fertility rates, and other indicators suggest it would be a population with a tendency towards growth. In addition, the results would support the model proposed by some researchers of decreasing residential mobility in the region, increasing population density, and the appearance of formal burial areas during the initial period of Spanish- indigenous contact.
