16 million / 25 million is 64%.

> not quite sure where you got 65% from

I'm not the original poster, but I mean, it's kind of obvious that it came from dividing literally the only two other numbers present in the comment you're replying to.

If the issue is that you disagree with those population numbers, then maybe say that explicitly and point to where you're getting your numbers from so that the point of contention can be identified instead of everyone just yelling that their unsourced numbers are better than the other person's unsourced numbers?
