On TIOBE, Julia (27) and Rust (20) are relatively close right now, and TIOBE might have some correlation to number of users. https://www.tiobe.com/tiobe-index/
And if you compare the IEEE to the TIOBE list, there appears to be a high degree of correlation. I think part of the criticism against TIOBE, is when people's favorite is not doing as well as they would like or a language they don't like is doing better than they expected.
