Wikipedia communities are often concerned about the quality of articles created by less experienced users. Having better visibility on the content that users produce at the different levels of expertise can be helpful.
This ticket proposes to measure for each user group (autoconfirmed, extended-confirmed, etc.) how many articles they have published with Content Translation, how many survived (total and percentage), and how many were deleted (total and percentage). For a comparison, the survival/deletion percentages can be shown for new articles that are not created with Content Translation.
This can be also useful to evaluate the effectiveness of the mechanisms Content Translation provides to encourage good quality translations (T190279, T190283, T190798).
