What method are you using? The 2e pop tables, the 10,000 per province level, or some other?
Not sure how you ended up with more pop for Taeghas than Avanil, when Avanil has 37 province levels (none below 3) and Taeghas has 23.
I know the method is contentious, Sorontar, but what about pursuing a compromise method? One that maybe starts with a base level of habitation (like Kgauck’s approach) and adjusts on top of that for province level?
The simplest form of this might look like saying that each settled province (about 1000 square miles) has a base population of 50,000. Every province level on top of this adds 10,000, representing both some additional population, but also largely level of organization and economic productivity. Then people can scale that base number up or down depending on what they think is appropriate, adding in whatever modifiers they wish.
I mention other modifiers because some things still would warrant adjustment to make sense. A few parts of Anuire are considered “frontier,” and a few would be characterized as more heavily settled, having been civilized for a very long time. You could let province levels bear this out or adjust the base number for these. Also, as noted, Elves seem to have a sparser population, and the Brecht seem to have far too many province levels, even having provinces specifically described as being all but uninhabited and yet being level 3 or so.
Anyway, adding a base of 50,000 per province would give Anuire (~150 provinces) a population of something like 7.5 million, plus maybe 4.5 million from the other population levels, or 12 million. It’s a starting point and compromise method, anyway. I might adjust it by setting the base for Frontier areas at 10,000 (Erebannien, Dhoesone, perhaps some provinces of Mieres, Coeranys, Roesone, Mhoried, and Talinie) and giving racial modifiers like Elves at 10,000 base, Dwarves at 40,000, Brecht at 40,000, Khinasi at 40,000, Goblins at 80,000. This would be mostly academic, since it wouldn’t have any impact on Domain collections, but it could be worked in via any mechanism that limits total possible military sizes or resilience to random events/recovery from province level loss.
Hope this doesn’t derail the thread too much. Looks like the OP was trying to find a standard method for determining population.
