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)
Yeah the data is kinda fucky cause of that, this has always been a factor too one of my ancestors spoke decent English but could only read and write in German he was considered technically illiterate.
It looks to me like it's ordered from more progressive to more fundamental, so literacy should be the last one, really. Trans rights is the newest major one, so it's the first to fall.
