Here is a quote from the BRCS for ya on that same page, “The difining domain-level measure of a province is not its size, but rather its level – its overall measure of its population, technology, and industrial prosperity.”
The BRCS p. 88 also goes on to say that the level provides a “rough metric for determining the number of loyal taxpaying human commoners in a rural province”, which means that they aren’t really reflective of the total population of a province after all. Firstly, because not all inhabitants are loyal, and secondly because not all inhabitants pay taxes (and some aren’t human either
).
I recently made some comments about more reasonable estimates in population on another thread (http://www.birthright.net/forums/index.php?showtopic=2740), that come up with some pretty good numbers (I checked against real world equivalents and there is good correlation).
While I am against the whole concept of “urban provinces”, as IMO The imperial City of Anuire is a unique historical case (alright, if you build a continental empire that lasts a thousand years, then maybe I’ll allow you to have an urban province). But, given my numbers, if I were to allow the creation of such divisions, I would just break off the most populous urban center of the province and say: “You’re urban”. That province would then gain a level corresponding to its city’s size on the total province population chart.
For example, say I have Ilien, a level 7 province with a total population of 216, 691. I want to emancipate the city of Ilien from the province. The population of the city would be around 13,306. So that means that the population of the rural province will take a blow, going down to 203, 685, but this isn’t enough to push the province down to level six (total pop 174, 182), and would recover eventually without too much trouble. The city of Ilien however, doesn’t quite have enough people to be considered a level 1 province, so instead it is a level 0 urban province and will have to be ruled up from there. In fact, only level 10 provinces boast large enough urban populations to spawn an urban province of level 1, and only provinces of level 6 or higher should be allowed to spawn level 0 urban provinces.
A reasonable restriction would be to say that only Metropolises (these only appear at level 10 in my charts) can be spun off into urban provinces, and that this follows the natural progression of provincial developement. Once a province hits the level 10 wall (which is dictated by land availability more than anything else. Only 12 counties in the world today have more than 40% arable land, about 3/4 have 20% or less) it enters a new stage in development by spinning off a city which gains a life and character of its own, independent of later effects to the mother city. Possibly a successful rule action on a level 10 province would instead of raising the province level, create a level 1 urban province which could grow from there. Of course it would be reasonably to say that any given province could only generate one urban province(all other major centers would be the UP’s metropolitan area). Heck, I’m just throwing out ideas now, cause its getting late :).
Anyway, I realize that my charts aren’t 100% applicable to independent cities, given that they are based on agricultural developement, but it would make things easier to standardize and just assume wouldn’t it? I also realize that they are nowhere near BRCS canon, and so probably will end up being irrelevant anyway, but now that I think of it, I like the idea of level 1 urban provinces being created by a successful rule of a level 10 province. It sort of explains where the population comes from (the previous urban population, and the rule action) and it gives the player a new province that still needs growth to reach its full potential.
