Do you find a good reference for the amount of contemporary written production per language? Chinese is often cited as the language that currently has the most native speakers (followed by spanish and the english); however written production doesn't necessarily have to follow that metric. For example I'm by no means a native English speaker yet my written production in english outweighs my native language production by several orders of magnitude (I mostly write grocery lists in my native language, that's it)
