**TL;DR Summary:**Quantum mechanical calculations are complex and the number of people capable of performing them is limited. In this thread, rough estimates are requested for the number of people that perform quantum mechanical calculations.

Please estimate - somehow - the number of people that can perform quantum mechanical calculations, in a sub-field, on a problem, in a country or world wide, whatever is informative....

For orientation, here are American Institute of Physics statistics on PhDs in Physics granted vs year.

https://www.aip.org/statistics/reports/trends-physics-phds-171819

See Figure 1 Physics PhDs Conferred in the US, 1900 through 2019

See Figure 6 on Sub-Fields, See "Quantum Foundations"

Finding the number of Physics PhDs in the US in a sub-field related to Quantum Mechanics would be a start.

I would like to get a rough idea of how many people have a high level of knowledge of quantum mechanics calculations. In particular, when a particular problem is discussed how many people world wide are capable of doing the quantum mechanical calculations?

Then, finally to know in a sub-field and on a particular problem in quantum mechanics, how many people more locally can do the calculations?

Please include any comments on how you estimated, including the sub-field, problem, country, suggestions, links for evidence, etc..
