That’s… horrifying. I had no idea it was that high. I have to wonder how anyone can be illiterate, after watching my kids learn to read, and how little effort it took (on my part I mean, they were putting effort into it, because they wanted to)
I should point out that a portion of the stat comes from immigrants who are fully literate in their native language.
National literacy as a topic forms an interesting picture that I don’t fully understand.
