Modelling age at death reveals Nordic Corded Ware paleodemography

Abstract

Drawing on modelling of age at death in skeletal remains, this article unveils hitherto unrecognized demographic patterns in the Nordic Corded Ware complex. This population formed part of the European Corded Ware complex that has been linked to disruption observed in the archaeological and genetic record. The newly developed methods of transition analysis 3 (TA3) and death rate ratio (DRR) were used to process skeletal data from 67 individuals deriving from single, double, and multiple graves in Scandinavia. The results disclose a high proportion of immature individuals aged less than twenty years. Attrition, however, complies with a demography with high age-nonspecific mortality, and this may connect to stressors such as epidemic diseases and endemic warfare. Compared to the partly contemporaneous Pitted Ware complex and the succeeding Late Neolithic–earliest Bronze Age period, the Nordic Corded Ware burials overall point to robust population growth, especially in the later period. This in turn aligns with a sedentary lifestyle rather than a mobile pastoral economy. Short-distance seasonal movements could fit in but cannot yet be measured. Recent genetics have demonstrated biological input in the female line from populations such as Funnel Beaker, Pitted Ware, and herders of the steppe forest zone: the remarkable tallness of Nordic Corded Ware individuals may well be an effect of such admixture. The burials moreover evidence a distinct adult male sex bias, which diminishes over time along with the growth in the number of buried females and young individuals. Judging from investment in graves and grave goods, immatures were highly valued. The scale of social status operates independently of age. Alongside the revealed Nordic Corded Ware demography and the burial and material record more broadly, this could indicate social inequality based on kinship and warrior values.
