Game development on Linux?

So was wondering if anyone had numbers for the amount of game developers who use linux as their development platform.

Not expecting this to be anything like the Linux server market share. But the development market has to be increasing and I have heard some programmers saying it is so much easier to install their preferred programming language on linux, as long as that language is not Visual C for windows, or Swift on apple devices.

And development environments like Unreal can’t hurt…
