More specific citation for first bullet
That's a good suggestion to move the UNESCO link into a footnote. Much better solution. So no objections to moving this to a footnote.
Good thinking :-)
I moved the UNESCO reference to the Notes section, including relevant data to facilitate re-accessing the data. I also expanded the note for the world bank reference.
I think standardising citations will be harder than I first thought, but this is another discussion topic. :/
