Testing the Accuracy of Basal Occipital Measurements and Discriminant Functions for Estimating Sex in European Populations

In the past decade, a number of studies from across the globe have indicated the potential for using dimensions of the basal part of the occipital bone for the assessment of sex in fragmented human skeletal remains. The majority of Studies use the dimensions of the foramen magnum (width and length) to carry out discriminant function analyses and/or linear regression analysis to estimate sex. These approaches have achieved sexing accuracy rates of between 60-70% for individual populations. Studies that use or include occipital condyle measurements have higher accuracy rates of up to 80%. Thus, while the occipital basal measurements should not be used in isolation for sex determination unless absolutely unavoidable, the region does have sufficient sexual dimorphism to be of value when dealing with fragmented archaeological remains.
