Articles created with Content Translation are more likely to survive than those created from scratch. For example, during 2019 the deletion ratio across all languages was 5% for articles created with Content Translation, while it was 11% for articles created otherwise.
However, some particular wikis have higher deletion ratios.

As part of the process of graduating content translation out of beta, we may want to understand better which is the situation in those wikis where translations are deleted more often. Similarly, for some languages it may be unclear whether they may benefit or not from some MT support of a closely related language.

Having clarity of those aspects would be helpful to adjust the tool in the best possible way for the community needs before moving out of beta.
