Suchey–Brooks method has been studied many times with varying reports of accuracy and reliability. A systematic review and meta‐analyses were utilized to quantitatively determine the accuracy and reliability of the Suchey–Brooks (S‐B) method. A systematic search of PubMed and EBSCO health and medical databases was performed. Meta‐analyses were performed to quantify the relationship between actual known age at death and the S‐B method using Spearman's Rho and Pearson's r for (1) combined males and females estimates, (2) male‐only estimates, and (3) female‐only estimates. Overall correlation coefficient using Cohen's kappa, Spearman's Rho, and Pearson's r was also calculated to determine the interrater and intrarater reliability using the S‐B method. Eighteen studies classified as moderate‐to‐high methodological quality met the inclusion criteria. The sample sizes were different for the combined male and female (n = 2620), male‐only (n = 2602), and female‐only (n = 1431) meta‐analyses. The effect size of the age at death meta‐analyses was large and significant for combined males and females (Spearman's Rho = 0.62; Pearson's r = 0.65), male‐only (Spearman's Rho = 0.77; Pearson's r = 0.75), and female‐only (Spearman's Rho = 0.71; Pearson's r = 0.71). The overall correlation coefficients of the interrater (Kappa = 0.76; Spearman's Rho = 0.73; Pearson's r = 0.80) and intrarater (Kappa = 0.81; Spearman's Rho = 0.91; Pearson's r = 0.83) reliability meta‐analyses were large and significant. A significant degree of heterogeneity was present in all meta‐analyses, with minimal evidence of publication bias. The meta‐analyses results suggest the S‐B method is highly reliable with a moderate‐to‐high degree of accuracy. Our results also identified sample size and accuracy differences between male and female individuals.

“…However, population‐specific methods are not always available, leading to a continuous discussion over the past decades about the applicability of Western‐derived aging techniques when studying non‐Western populations (e.g., Gocha et al, 2015; Herrera & Retamal, 2017; Jones et al, 2018; Joubert et al, 2019; Kotêrová et al, 2018; Ruengdit et al, 2018; Sakaue, 2006; Shedge & Kanchan, 2019; Singsuwan et al, 2019). For example, a combination of Western‐derived age‐at‐death estimation methods was used in all 20 papers that investigated research questions using archaeological populations from East Asia, though this might be an artifact of sample bias in our data collection (i.e., our search criteria did not include lesser‐known, regional‐specific methods, though they were noted when found and are listed in Table S1).…”

Accurate and precise age‐at‐death estimation methods are critical when studying past lifeways. However, adult age‐at‐death estimation is often difficult because of diverse physiologies, preservation, and timing of biological processes in target and reference populations. These challenges can complicate the comparison of results between studies, which can also be impacted by the training and method preference of each bioarchaeologist. In this paper, we first compare the use of two types of age‐at‐death estimation methods, namely, traditional methods (e.g., pubic symphyseal aging) and Transition Analysis. Second, we build upon the work of Falys and Lewis (2011), who reported frequencies of adult age‐at‐death method use between 2000 and 2010, by reporting the frequency of use for traditional methods over the past 40 years with special attention on the last decade. We build further on their work by identifying trends in the minimum age at adulthood, adult age categories, geographic region of institutional affiliation of the first author, and the geographic region of sample origin and interpreting their possible implications on comparability of bioarchaeological literature. Our results show that Transition Analysis, institutional affiliation, and sample origin do not represent major sources of variation in bioarchaeological literature so far. In the case of Transition Analysis, this could result from its limited use thus far, while institutional affiliation and sample origin do not represent major sources of variation because of the relative lack of diversity in both variables. There was, however, substantial variation in the type of traditional method used, the minimum age at adulthood, and adult age categories, which could affect comparability between studies. Our study highlights the need for continued discussion about standardizing bioarchaeological age‐at‐death estimation while respecting the unique needs of diverse target samples.

“…Moreover, Wärmländer and Sholts, 2011 used the Suchey-Brooks method in two populations (Europe and Asia). Furthermore, Joubert et al, 2019 studied white South African populations with moderate positive correlations. In our study, we had a limited number of young samples (20-40 years).…”

The auricular surface and pubic symphysis are commonly used in age estimation. This study aimed to compare the results of age estimation between dry bones and 2D images of the os coxae and to develop a tool specifically for Thai individuals. The total samples were 250 left os coxal dry bones divided into 200 samples (100 males, 100 females) for the training set and 50 samples for the test set. The age range was 26 – 94 years. We used the Suchey-Brooks method and Berg method for observing the pubic symphysis and the Buckberry-Chamberlain method for observing the auricular surface. Afterward we compared the dry bones and photo parts. Our results showed sex did not play a significant role in estimating the age-at-death. In both parts, the auricular surface yielded the highest accuracy (80 – 84%) with SEE = 13.99 – 14.24 years. The pubic symphysis showed an accuracy of 74 – 76% and SEE = 14.37 – 14.44 years. The results of the dry bone and photo parts did not differ significantly. In both dry bone and photo parts, the intra-observer agreement performed moderate to almost perfect agreement. On the other hand, the inter-observer agreement was slight to fair. In conclusion, our study can be potentially applied for distant consultation for age estimation using 2D pelvic images with a forensic anthropologist for estimating biological profiles.
