This PhD-project investigated the demography of Late Upper Palaeolithic hunter-gatherer populations, when Europe was repopulated after the Last Glacial Maximum. The study deals with estimations of regional differentiated population densities and associated settlement patterns.
A method based on GIS techniques is used to upscale archaeological data from key sites and regions to culturally homogenous contextual areas in Europe.
Based on the spatial density of Late Upper Palaeolithic sites, GIS-calculated regions are interpreted as indicators for settlement areas of Magdalenian and Hamburgian hunter-gatherer groups. The origin of raw materials from key sites indicates the seasonal or annual range of forager groups. Size relation of settlement area and raw material catchments is an indication for the number of hunter-gatherer groups in a region. Ethnographic records relating to hunter-gatherer societies practicing similar subsistence strategies as Magdalenian foragers are taken to reconstruct the size of prehistoric groups. These results are checked by control parameters like on-site information about settlement sizes, duration of stay and seasonality. The outcome of observing the changes and movements of population during the time period of Late Upper Palaeolithic as well as comparing the differences and similarities of regional differentiated population densities is a further contribution to our understanding of settlement patterns and migration indicators of Palaeolithic hunter-gatherer in Europe.
