When it comes to statistics, the surveys conducted by the Société Française des Traducteurs (SFT) are a reference. The previous one was conducted in 2015; now you can have access to the new one for 2022. From June 30 to July 18, 2022, an online questionnaire was sent, via an e-mail link, to the SFT membership database (approximately 1,600 contacts).
You can consult the results here. You can also have access to the analyses, a video presentation and more information here.
