Three trace elements in human bones permit the delineation of temporal and social variability among medieval to early modern Danes in what they ate (strontium, Sr) and whether they lived in an urban or non-urban setting (lead, Pb; copper, Cu). The chemical composition of bones from 332 children (5 to 12 years old) buried in 51 Danish cemeteries was estimated through Inductively Coupled Plasma Mass Spectrometry (ICP-MS). Children provide a local chemical signal because they were less likely than adults to have moved from one place to another. There was no age effect on trace element concentrations. Geographical variability in trace element concentrations was highly localized, so the three elements, individually or collectively, cannot be used to identify where in Denmark people originated. Diets and exposure to sources of Pb and Cu, however, did not remain constant over time. Trace element concentrations show that the life experiences of people from towns differed from their rural counterparts. While most apparent with Pb and Cu, it is also true of Sr until urban and rural diets converged in the early modern period.Keywords: Historic Denmark; Bioavailable trace elements; Social variation; Temporal variation; Human skeletons; ICP-MS
