It's probably not the latest estimate, but having rechecked my textbook, it deffinitely said 11Bn by 2050, only for it to decrease to 9Bn by 2100. It's not an old textbook either (made in 2013).

It says by the close of the 21st century.

Yes, but like I said, there are several estimates, all "official", from different organizations, neither is correct nor wrong
