This dataset was compiled for the master's thesis "Familiar Feet. Kinship analysis using foot anomalies in the cemetery of Middenbeemster (Netherlands, 17th to 19th century)" at Leiden University (Netherlands) by the author. The thesis was submitted on June 15th, 2021 ( https://hdl.handle.net/1887/3204807 ). The data was collected in the period from January to May 2021 at the Laboratory of Human Osteoarchaeology at Leiden University. It includes the data of 380 adult individuals from four different post-medieval, Dutch populations: the rural population of Middenbeemster (MB) (Hakvoort 2013) and the urban populations of Eindhoven (Catharinakerk) (EH) (Arts 2013), Zwolle (Broerenkerk) (ZW) (Clevis and Constandse-Westermann 1992) and Arnhem (Eusebiuskerk) (AR) (Baetsen et al. 2018). For every individual, an estimate of sex and age-at-death was collected. If a DNA analysis was performed, then this result was used instead of an estimation.The sex estimations of the individuals were based on pelvic and cranial morphology (Bainbridge & Genoves Tarazaga, 1956; Bass, 1987; Buikstra & Ubelaker, 1997; Maat & Mastwijk, 2009; McCormick et al., 1991; Phenice, 1969; Stewart, 1979; Steyn & Işcan, 1999; Workshop for European Anthropologists (WEA), 1980) and were supported by archival data. For the Eindhoven collection, the DNA-determined sex estimations took precedence over the estimations by traditional bioarchaeological techniques (Baetsen & Weterings-Korthorst, 2013). The used abbreviations are M = male, PM = probable male, I = indeterminate, PF = probable female, F = female. Age-at-death estimations were made according to traditional bioarchaeological techniques (Brooks & Suchey, 1990; Buckberry & Chamberlain, 2002; İşcan et al., 1984, 1985; Lovejoy et al., 1985; Maat, 2001; Meindle & Lovejoy, 1985; Todd, 1920). The used abbreviations are EYA = early young adult, LYA = late young adult, MA = middle adult, OA = old adult. The foot anomalies included are accessory navicular (AccessNav), ...
