I'm putting together a series of posts, and in the last one #615256 make me think about literacy rates and how this minor detail could have affected our current life if higher at the beginning of the 19th century. We had the printing press since the 15th century, newspapers since the 18th century... but how many were lucky enough or had the time and access able to learn?
I found a few interactive charts I though may be worth to share. Can you find a better one? is the place where you live over or under the world average?
