One thing I haven’t noticed anyone else mention is that the literacy data being referenced here seems to originate from the PIAAC, an organisation that I wasn’t previously familiar with. I was curious about their methodology, since I also thought the quoted rate was shocking. The thing is, according to this FAQ, they only assess in English. So the number of people who are actually illiterate is inextricable from the number of people who are literate in another language, but haven’t learned English yet.
