The sourcing of cadavers for North American skeletal reference collections occurred immediately after death and targeted the poor and marginalised. In Europe, collections sourced bodies that were buried and unclaimed after some time in cemeteries with no perpetual care mandate, and may have also targeted the underprivileged. The relationship between socio-economic status (SES) and abandonment was examined in a sample of unclaimed remains (603 adults and 98 children) collected from cemeteries in the city of Lisbon, Portugal, that were incorporated in a collection. Results demonstrate that low SES individuals are not more likely to be abandoned nor to be incorporated in the collection than higher SES individuals. Furthermore, historical data indicate that the poorest were not incorporated into the collection, because of burial practices. Although the accumulation of collections in North America was facilitated by structural violence that targeted the poor and marginalised, this phenomenon seems largely absent in the Lisbon collection.
