By "UX designer", I mean those who are practicing one or more of the following as their profession: Information architecture, interaction design, visual design, or user research. I'm just trying to get a sense of how large our profession is without precipitating another heated debate about the "UX designer" moniker.
1Welcome to UX.SE! Answers to this question are going to be fairly opinionated as there are no authoritative sources that track this type of information. Particularly when IA, UX design, visual design, and research often fall across a broad spectrum of job titles and descriptions.– Charles WesleyApr 1, 2014 at 18:34
Yes you are right. It is a little subjective because it depends on what term you use and where you go. Every country is different.
According to LinkedIn stats, dated as of today there are over 900,000 UX Designers on the LinkedIn network.

I'm not sure that "connected to", as the infographic says, is the same as actually "being". When I do a people search on LinkedIN with the keyword "UX design", the results returned are just under 27,000. For "UX designer", it's just over 17,000. Then again, that's for the US only. I didn't do a search for each country. Still, I wonder if that total would be close to the 1 million stated in the infographic. I'd love it to be true :)– VdudeApr 1, 2014 at 19:57
As mentioned, every country is different. It could be a different job title somewhere else. Who knows what it's called in other languages..– PdxdApr 1, 2014 at 20:16
