Accurate estimation of ages at death and adequate sampling represent two major concerns in palaeodemography. This paper addresses the relevant particular problem of the treatment of samples that include some individuals of incomplete preservation resulting in non-specific age estimates. A procedure of weighting the values in appropriate age intervals is recommended when ages at death can only be estimated generally for a limited number of individuals in the sample and more accurate estimates are available for other, better preserved individuals. This problem is usually encountered with adult individuals. In such cases, the weighting procedure is recommended over complete exclusion or use of the mean age value of the wide age estimate.
