I've looked at this all over the interwebs and haven't found much consensus, so I figured I'd come and ask "those in the know."
In the Star Trek reboot, after the destruction of Vulcan by grief-stricken, anachronistic Romulan miner-turned-terrorist, Nero, NuSpock states that only about 10,000 Vulcans survived, leaving his father's race "an endangered species."
Presumably that means about 10,000 Vulcans that were on the homeworld at the time managed to evacuate, including the members of the High Council that Spock rescued from the Katric Ark (and weren't crushed to death by collapsing statues or earthworks).
Okay, all sarcasm aside, how many Vulcans do you suppose are actually left post-destruction of the homeworld? I cannot believe that there weren't Vulcans assigned to Starfleet vessels (or stations, outposts, or Starfleet Command itself) that were not destroyed by Nero during his initial attack on the fleet at Vulcan. Further, there were certainly Vulcan ambassadors, negotiators, scientists, physicians, and other professionals elsewhere in the galaxy... perhaps not too many, but some. Finally, there are [according to canon] at least a handful of purely Vulcan colonies throughout Federation space (and perhaps beyond) as well as multiracial colonies with at least some Vulcan residents.
Oh, and what about whatever remains of the Vulcan Space Service (or whatever other Vulcan organizations remain post-UFP formation)? I would think there were still some mid- to late-22nd century Vulcan cruisers (as well as other Vulcan ships, both older and newer) still cruising around with primarily [or entirely] Vulcan crews as well.
Moreover, there are other Vulcanoids and proto-Vulcanoids (including the Romulans, Mintakans, Rigelians, any surviving Debrune, etc.) scattered throughout the Alpha and Beta Quadrants as well. Now, granted, it seems unlikely that the remnants of the Vulcan High Council on New Vulcan would start recruiting non-Vulcans (or abducting Mintakans to expand their gene pool), but perhaps "desperate times call for desperate measures." This is also a great scenario for Romulans to infiltrate the new Vulcan society...
So, since I think 10,000 surviving Vulcans c.2258 seems unbelievably low, I was wondering what you all thought. What seems reasonable? 50,000 Vulcans? 250,000 Vulcans? A million? Ten million? With a presumed population of about least 4.9 billion (according to http://memory-beta.wikia.com/wiki/Confederacy_of_Vulcan), even 0.01% of the population is 490,000. A population of 10,000 surviving Vulcans is only 0.000204081633% of 4.9 billion.
On a tangent, what do you suppose this does to Vulcan technical knowledge and expertise? I don't imagine all of their scientific and technological achievements disappeared with the destruction of their planet, but certainly the loss of the Vulcan Science Academy would be a huge blow to future Vulcan invention and discovery. That, combined with the loss of [most likely] the bulk of the Vulcan intellectual elite, would certainly limit the influence of Vulcan science and engineering in the "new reality."
So what Vulcan technology remains? Ships? Stations? Outposts?
What remains of the Confederacy of Surak in the NuTrek universe?
