There aren't going to be any changes/additions to the API for a while. It's currently in maintenance only
Datas to bachelor

You could contact Support directly to ask about the data but I'm not sure that's something that would be provided.

I asked support and they told me to contact here
There are no API endpoints that would be able to provide the data you're looking for

"I wanted to point out that the best contact point for obtaining the information we can share is the link below, by reaching out and posting in the appropriate team --> https://www.chess.com/club/chess-com-developer-community They will respond and share all the necessary information with you!"
This is information I get

In this particular case, the Public API isn't going to be able to help. The available endpoints can be used to gather information but none of what you're looking to get is available through it

You might be able to use the Internet archive to get some decent estimates on totals. There's no way to get the country level totals, though you might be able to play a proxy if the Internet archive has snapshots of the country leaderboards for blitz and rapid. That will only have active players at those times
I am a third-year student of Econometrics and Data Analytics at the University of Łódź. I am currently preparing my bachelor’s thesis titled: “Factors Influencing the Average Chess Rating.”
As part of my research, I kindly request access to monthly statistics on the number of online players on the chess.com platform, broken down by selected countries. These data would be used solely for academic purposes and would be extremely helpful for conducting a comparative analysis within the framework of my thesis.
The data that would be particularly valuable for my research includes the total number of players on chess.com globally for each year from 2015 to 2023. Within this period, specific data for Poland and the United States would also be especially useful.
Additionally, if possible, I would greatly appreciate access to the number of players from the following countries as of December 2019, December 2021, and December 2023:
Czech Republic, Germany, Estonia, Greece, Spain, France, Croatia, Lithuania, Hungary, Poland, Portugal, Romania, Slovenia, Slovakia, Sweden, Switzerland, Serbia, Turkey, and the United States of America.
I assure you that all data will be used exclusively for academic purposes and treated with full confidentiality. Any form of acknowledgment or citation you may require will be duly included in the final version of my thesis.
Thank you in advance for considering my request. I would be extremely grateful for any assistance or guidance you could provide in this matter.
Kind regards
