Legend
I wouldn't rely on the grammar of a fan wiki to prove your point. From the show itself, 900M appears to be the number of people who needed rescuing. Yes, it seems low. But hey. Star Trek.
I dunno, it's pretty vague. It may have been the Federation's contribution to the evac effort. Perhaps the Romulans rescued more on their own. The main thing we know is that the Federation evacuated SOME people, but not as many as they promised. Of course, it turns out they had a pretty good excuse, if the ships they were fast-tracking to do it all got blown up by some crazy synth uprising.
