Regional statistics / demographic analysis of global licensed SketchUp users?

Hi everyone,

Is there any geographic or regional analysis available regarding global SketchUp users? I’m looking for academic research, industry reports, or statistics showing which countries and cities have the highest concentration of active, licensed users.

Does anyone know if such data is publicly available, and where I might find it? Any pointers would be greatly appreciated.

Also, what do you think about starting a poll here on the forum to see where everyone is participating from?

Thanks!
