A large modern Southeast Asian human skeletal collection from Thailand.

The Khon Kaen University Human Skeleton Research Centre has a large human collection consisting of 745 modern northeastern Thai (Isan) skeletons derived from bodies bequeathed to the Department of Anatomy during the period 1979-2014. The aim of this paper is to document the collection and address the question of whether the collection may be representative of local Isan people, or populations of the wider region of mainland Southeast Asia. This will determine its value as a reference collection for forensic anthropology in particular but also for all other fields of research about human skeletal biology. Sex is recorded for 99.6% of the skeletons, and age at death for 91.7%. The collection consists of two-thirds males, one-third females. It includes 10 individuals less than 19 years of age, and adults ranging in age from 20 to 109 years of age. Average age at death is 62 years. Other data available for smaller proportions of the collection include cause of death, occupation, and height and weight at the time of donation. Dates of birth are estimated to range from the late 19th Century to the most recent in 1988. Analysis of the demographic composition of the collection shows that is likely to be representative of the ancestral mix of the Isan people, and of the village farmers who still form a large portion of the Isan population. It may also represent 20th Century populations of much of Southeast Asia where agriculture dominates the economy. The collection forms a valuable resource for research on regional human skeletal characteristics for use in forensic anthropology.
