[Categories of variability in the thickness of human skull bones].

Problems in standardization of the thickness of skull vault bones at certain strictly determined points are discussed. Race, ethnic, regional, and sex-associated variability of this criterion was studied on extensive material for many peoples of the world (1261 men, 549 women, and 570 men + women). The most significant differences are characteristic only for the male and female totalities. A table of categories of the skull bone thickness has been created, covering 5 intervals with the following incidence: 33% medium, 22% low and high (each), and 11% very low and very high (each). An expert example is offered.
