I don't know the exact number, but I imagine that there must still be a smaller population than it had in Ingnam, since it is necessary to have a good number of people to be able to "voluntarily" send a "Champion" through the portal every years!
In Hawkethorne, I remember that it was said that people usually disappear every year in that region, always around the same time, but that many times this happened to a passing traveler or they simply blamed the forest beasts!
Not to mention that it would be difficult for a village to maintain a large population in an environment as rigid as the Frost Marches!
All this, of course, would be before our arrival, since even if you maintained a monogamous relationship with the beautiful innkeeper's daughter, you would still have a battalion of puppies running around.
