Hey folks, hope your Friday's going well.
I'm on the hunt for an interactive map that shows how many BTC miners or farms are in each country. Is there a map like that out there?
Came across this one => https://chainbulletin.com/bitcoin-mining-map/
but it looks like it only covers pools, not individual miners.
Appreciate any input you guys have.
There is really no way to know. Mining pools do not publish where people are mining from so all you can see are the pools.
Even if the pools did say where the work was coming from it would be a guess at best. They only know the IP that the work came from between VPNs & proxies it would be a general guess at best.

I think we can safely assume that the vast majority of miners don't mine behind VPNs, and the map provided in the OP goes in line with the study from Cambridge, and I believe they use the same data since the numbers look pretty similar, you can read more about the "data aggregation and analysis" they used here, but long story short, they get these data from (BTC.com, Poolin, ViaBTC, and Foundry) and separate it by IP addresses, the last update was April 2021 when those pools made about 35% of the total network hasharate, while you can't take this info to the bank, I believe it's accurate to a fine degree.
Of course, with the recent shutdown in China, these figures must have changed a lot, but at least at the time of posting them, they were fairly accurate.
I'd very much doubt the accuracy of that map.
To get it accurate would require pools to constantly share IP address information about the people mining on their pools.
That information is, to be blunt, a major issue to provide to anyone since each IP is directly related to one person/company/datacentre.
The range from a 'node' to the miners mining on it can be 100s or 1000s of kilometers.
If the network is high quality, these distances might not be problematic, and, well, the miner has to choose a node to mine to, so if their choice of pool doesn't provide a node very close to them, their choice of node could be a long way away.
Also of course it's not accurate due to the obvious:

Even if they did get all that information accurately back in Oct 2020 (which they couldn't) it's gonna be far from accurate today.
