I haven't finished yet, so it only 60% of Federation worlds survived or 60% of all Starfleet vessels survived?
Starfleet suffered a loss of 40%. The most conservative estimate for the death toll is about 63 billion combined Federates, Klingons, and Romulans (Star Empire and Imperial State).
From page 420 of Lost Souls
Bacco found it difficult to read the next portion of her address, but she had no choice. The truth had to be faced.
"It is unfortunate," she continued, "that at a time when we should be rejoicing in our victory, we must mourn losses so tragic. It's natural, at a time such as this, for us to think of ourselves. We had not yet completely recovered from the Dominion War, and now dozens of worlds--including Deneva, Coridan, Risa, Regulus, Korvat, and Ramatis--lay in ruins. Dozens more, including Qo'noS, Vulcan, Andor, and Tellar, suffered devestating attacks. And we must remember that the Borg did not discriminate between us and our unaligned neighbors. They inflicted widespread damage on Nausicaa, Yridia, and Barolia.
We know from Book I that all life on Ramatis was exterminated, as was all life on Deneva. Given Bacco's inclusion of them in the first list, I would presume that this means that all life was exterminated in Coridan, Risa, Regulus, and Korvat as well. Presumably, this means that the Coridanite, Risian, and Ramatian species are now critically endangered if not functionally extinct (in spite of their world's Federation membership). No clue whether or not surviving members of those species be repatriated into other Federation Member States or if they'll somehow retain their own Member State status if they resettle. (Will the Federation go from 155 Member States to 149?)
We know from page 416 of Book III that 77 million Klingons died on Qo'noS, so we can probably presume similar death rates for Vulcan, Andor, and Tellar -- probably roughly 60 to 80 million deaths. I would imagine the same to be true of Yridia, Nausicaa, and Barolia.
Did I miss anything? Did anyone ever compile a comprehensive list of Federation Member Worlds that were destroyed? Or of Federation species homeworlds that were destroyed (since we know that Deneva was a Member State but not any one species' homeworld)?
