I'm curious because if you take into account the number of Horde and Alliance members that have died during the time span from the first war to present (Think of the Third war). If you really think about it the birth rate would have to be insane to sustain the losses that the scourge and any other conflict has dealt to the Alliance and the Horde.
Now let's take a look at the approximated numbers from WOWWIKI
http://www.wowwiki.com/Horde 292.100 Members
http://www.wowwiki.com/Alliance 800.000 Members
http://www.wowwiki.com/Stormwind_City 200.000
http://www.wowwiki.com/Orgrimmar 14.000
These numbers are extraordinarily low and unrealistic (These numbers take into account EVERY minor group in the both factions). What is also curious to me is the fact that assuming that both the factions are centered around the cast system (?) a very high number of the populace serves in the military government.
I might be thinking about this WAY to much, but this has been bothering me for a VERY loong time.
I'm opening this thread to start a discussion thread about the population numbers of both factions.
