I touched on this in one of my earlier messages in this thread.

I have no clue about proper numbers for population, but Mats imaginary friend had this to say earlier and he seemed to know what he was talking about:


So lets say 150 million people total over the entire continent.

Now lets see the RJ quote that he made about channeler numbers:


Seems likely that the Seanchan with the damane not having children, male sparkers hunted down and killed, and the sul'dam likely not leading normal family lives, will all also result on culling the ability so the 1% is likely accurate for the Seanchan too.

RJ unfortunately does not clarify about sparkers. That could mean that something like 0.1% of the population have the spark. Or it could mean that say 1% of channelers(who are already rare to begin with) will also have the spark. Which would reduce numbers even further.

Even so, considering the long lifespan of the damane due to no oaths, the testing that will find everyone, and the fact that rebellions and the like will likely not have caused any significant loss in the damane numbers, the Seanchan likely have a LOT of channelers at their disposal.

Obviously however the Seanchan did not have traveling when they arrived, so they could not fill their ships to the brim with channelers, they could only bring a limited supply with them.

Ofcourse that has changed now. I mentioned in another message that Rand should actually be thanking Semirhage. If not for her killing the Empress&co and throwing the entire Seanchan into chaos and civil war, Tuon could likely have used traveling to summon virtually all the damane in Seanchan to support her and utterly crushed Rand, the Aes Sedai and pretty much everyone else with ease. That however will no longer work. Her authority back home has been destroyed and she has to rely on the numbers she already has.
