The user testing market

[juliette piazza]

Hello,

Do we have any data on the user testing market? Like for example:

-  how many user researchers are in the Europe, US or even worldwide?

-  how many user testings they are generally doing per month or per year?

-  which industry is doing the most of user testing? ( public government, airlines companies, banks...?)

Thanks a lot.

Juliette
