If you read “Eurostat (2023)”, can you identify the author(s)? Can you tell where (if at all) this was published? Do you know the title of the publication? No. You have to search for all of these things (as you did – thank you) given only two keywords. And if you find something, you can’t be sure if what you found really is the source of this image, or if it’s another edition or if it’s just a different publication which also doesn’t properly cite its own sources.
