As suggested by Tim, I’ve been reading about Anthropometry, which is is the study of how to measure human’s bodies. There are tons of manuals and research surrounding this topic. In the book Anthropometry: Human Body Measurements and How to Use Them by Beata Mrgalska and Waldemar Karwowsk (2024), the authors ackowledge that there will never be an average human in Anthropometry. They say: there is no such thing as an average human or a 50th percentil human.

They also mention how there’s a lot of popultation sampling problems and how antropometric database is quite complicated to be fully standarized, so they say it’s necesary to compromise since the lack of data:

“The cost and logistical difficulties involved in such surverys will probably limit them to the more prosperous nations for the forseable future so that the development of a truly global anthropometric database is unlikely for many years to come.”

This book helped me visualize: there’s an akwnoledgement on the gap but here’s also an aknoledgement on how it’s easier utilizing incomplete data base, since it’s what exists. As Caroline Perez Criado mentions on her book, theres in gener a lack of data that faciliates like thought only for men.
