We'd like to know how many editors who edit on Wikidata also edit on one of the other Wikimedia projects and which ones those are. This will help us get a better understanding where the editors are coming from inside Wikimedia and where we still have a lot of work to do for better integration. Someone counts as editing on a project if they've made at least one edit in the given month on Wikidata and that project. The numbers should be broken down by language (for Wikipedia) and project.
