title: Pubic symphysis age distributions.
abstract: A further discussion of age assessment and palaeodemography requires detailed reviews of methods, especially pubic symphysis techniques. Before reanalysis of changes in symphyseal form, the initial steps in distributing ages must be examined. Use of the mean values for age scores gives age distributions that are not real, but subject to systematic distortions, and cumulative percentages of skeletal samples can be shown to reflect the mean ages. Distributing skeletal ages using 95% probability distributions provides a more accurate estimation of true ages for palaeodemography and a better basis for discussions of pubic symphysis aging techniques.
