The Maiden Worlds were, by definition pretty much, uninhabited at the time of the Fall, most remain so. The Eldar Empire wasn't like the Imperium, it didn't stretch from one end of the galaxy to the other in a string of occupied worlds. The Eldar Empire ruled the galaxy simply because the Eldar were untouchable in their might. Aliens were all over the galaxy during this time while the Eldar remained primarily in the area that would become the Eye. That's how humanity was able to spread across the stars, to occupy large parts of the current Imperium, while the Eldar were still ascendent. The Eldar didn't live everywhere, but they ruled everywhere.
The Eye ripped away the entire heart of the Eldar Empire and almost the entire race died.
Add in all the Dark Eldar in the Webway, and the 10+ Craftworld Eldar on their country size ships make me fully believe in no way in hell could the fall killed more than 3 quarters of the race. By statistics that should be impossible,
I'm curious as to what statistics you're using to support the idea that the Eldar Empire, a race of such power and plenty that it ruled the entire galaxy with unquestioned might for millennia, was around 100 worlds in size (since the Craftworlder's have around 10 worlds if we're generous and the DE maybe half as much again with the Exodites being negligible in comparison). The Imperium is a million worlds and it's reign is not as unquestioned as the Eldar's was. While technological and psychic ability certainly contributed to their dominance, there's simply no way they could've been the galacitc power with an empire that size.
I cannot be convince anyway they were so nearly wiped out. Especially when in the codex its states the Eldar Birth Cycle cannot compete with the other races which is why the (key word here) Declined over time. Not nearly wiped out to extinction, they were declining over 10,000 year period to it.
The Eldar codecii's both state that the Fall was an apocalypse and that the race basically died on that day. There simply isn't enough time since the Fall for slow breeding to have crippled the Eldar so extensively, seeing as their only like one or two generations out.
