“…The most frequently used and well accepted techniques for estimating age in adult skeletal remains involve an analysis of the pubic bones . Numerous methods for age estimation via the pubic bones are available; two such methods are those of Chen, Zhang, and Tao (subsequently referred to as Chen et al.) and Brooks and Suchey (hereafter Suchey‐Brooks) .…”

“…method focuses on nine morphological features of the male pubic bone in a Chinese Han population. These features are: (i) ridges and furrows on the symphyseal surface; (ii) ridge of pubic tubercle; (iii) lower extremity; (iv) ventral beveling; (v) ossific nodules; (vi) dorsal margin; (vii) ventral rampart; (viii) general macroscopic changes of symphyseal surface; and (ix) bone density of the symphyseal surface . Each of the nine features is divided into three‐, four‐, or five‐stage categories and assigned a respective score of 0 through 2, 3, or 4.…”

Accurately estimating the age-at-death of adult human skeletons is fundamental in forensic anthropology. This study evaluates the accuracy of two pubic bone age estimation methods-Chen et al. and Suchey-Brooks. Specimens were obtained from a known collection of modern pubic bones curated at the Maricopa County Forensic Science Center in Phoenix, Arizona. A sample of 296 left male pubic bones of European ancestry was statistically evaluated via bias, absolute mean error, and intra- and inter-observer error. Results indicate that the two methods are similar; the Suchey-Brooks method is the most accurate for aging young adults (error c. 7 years), while the Revised Chen et al. method is most accurate for aging middle-age adults (error c. 6 years). Thus, the Chen et al. method is an important contribution to forensic anthropology for aging older adult skeletal remains. There are, however, some limitations such as subjectivity and the intricate scoring system of Chen et al. method.

“…Few studies have used subjects from other geographic areas [21]. This is valid for both the pubic symphysis senescence method [15,[22][23][24][25][26] and the facies auricularis age modification method [27][28][29][30][31][32][33], where both structures were evaluated simultaneously [10].…”

“…The simplicity and rapidity of a method make it a useful tool for quick evaluation of indicators and cheap estimation in forensic and archaeological context. Pubic symphysis and auricular surface of the ilium have been largely exploited to create methods, but these were based on observations of a single population [22][23][24][25][26]. One of authors has tested her method based on a worldwide learning sample [27] using a Bayesian prediction approach in order to classify individuals in age range categories.…”

We discuss here the estimation of age at death from two indicators (pubic symphysis and the sacro-pelvic surface of the ilium) based on four different osteological series from Portugal, GreatBritain, South Africa or USA (European origin). These samples and the scoring system of the two indicators were used by Schmitt et al. (2002), applying the methodology proposed by Lucy et al. (1996). In the present work, the same data was processed using a modification of the empirical method proposed by Lucy et al. (2002). The various probability distributions are estimated from training data by using kernel density procedures and Jackknife methodology. Bayes's theorem is then used to produce the posterior distribution from which point and interval estimates may be made. This statistical approach reduces the bias of the estimates to less than 70% of what was obtained by the initial method. This reduction going up to 52% if knowledge of sex of the individual is available, and produces an age for all the individuals that improves age at death assessment.
