Yeah, good point. There has been the population explosion, but putting numbers on it is very tough. KSA gov says "20Million," let's negotiate that down. I might buy 12Million, but more than your number.

The 12 million figure would have to be adjusted to account for the 35% of the population presently estimated to be foreign workers. That kicks it down to 9 million which is not too far away from my estimate (which I feel is too high anyway).
