Equations for predicting body mass from stature and bi-iliac (maximum pelvic) breadth have been developed, but have had variable success when applied to living or recently deceased individuals, calling into question their general applicability. Here we test these equations on a large, ethnically diverse sample. Skeletal and anthropometric data for 507 recently deceased Indigenous, Hispanic, and non-Hispanic White adults were obtained from the New Mexico Decedent Image Database. The body mass of individuals with a “normal” body mass index (BMI = 18.5–24.9) is very accurately predicted, with an average directional bias of about 1% and an average random error of less than 8%. Underweight individuals (BMI < 18.5) are overpredicted, while overweight (BMI = 25–29.9) and especially obese (BMI≥30) individuals are underpredicted. Within BMI categories, there is a strong and isometric relationship between predicted and true body mass. Individual body mass prediction errors using the stature/bi-iliac method are mainly dependent on variation in BMI. Because earlier humans were more likely to fall within or close to the normal BMI range, the equations should be applicable, on an individual basis, in archeological and paleontological contexts. Because of the prevalence of obesity in many modern populations, these equations are not applicable in a general forensic context. We derive new equations from nonobese individuals in our sample (n = 338), which produce reasonable average prediction errors. If obese individuals can be identified using other skeletal parameters, these equations may be useful in estimating body mass in nonobese forensic cases.

While there has been increased awareness of the ethics of curation, research, and teaching with human skeletal remains, there has been little recognition of the millions of skeletal remains from South Asia that were harvested illegally and/or unethically for educational institutions globally for over a century. This article gives a contextualization of the unique history and nature of anatomical teaching collections, and why they are an important locus for a decolonized and antiracist biological anthropology. I present the historical background of how the exportation and commodification of Indian bodies came to dominate the global bone trade. I also discuss how historical necropolitics explicitly erased the identity and objectified South Asian people made into study skeletons, and the way our current practices continue to uphold colonial violence. Finally, I discuss what we might do with these historical collections and the ways that inclusion of Brown voices is critical to ethical practice.

When considering the best ethical practices in forensic anthropology, one must consider how accessible the field is to new students that are responsible for driving the future of research, pedagogy, and the field as a whole. While there is no denying that there are multiple barriers to accessing academia (e.g., racism, sexism, xenophobia, etc.) the cost of a graduate education is a key factor that affects the diversity of people that are able to enter the field. Here, the cost of 24 universities prominent in the education of forensic anthropologists are considered in tandem with the opportunities for funding offered by these institutions and average costs of living for the respective surrounding areas. Demographic data for the universities at the graduate and undergraduate level was additionally compared with the demographics of the cities surrounding the universities. Funding, excluding loans, was shown to be greatly below cost of living in university cities, and often did not match the costs of attendance estimated by institutions. Including the cost of living, the average graduate degree costs over $60,000 per year while the average stipend for graduate students is below $14,000 necessitating the need for loans or out-of-institute support. White individuals were overrepresented in graduate enrollment when compared with surrounding area demographics, even when university demographics were similar to those of the surrounding area. Overall, findings highlight the inaccessibility of pursuing higher education for minority groups and demonstrate the need for institutions to develop funding programs to promote diversity in higher education.
