How do you handle the number of supernaturals in your own games?
So this is more of a discussion question rather than being about some specific splat such as vampire or werewolf. From what I have seen the number of supernaturals given by white wolf are often seen to be on the low side(Which I agree with. Like there are a total of 690 vampires in the entirety of France. There are ten thousand intact castles there and you are telling me that only six percent of them are inhabited by a vampire? Don't get me started with Mage with there being only 58 mages in England meaning most cities either don't have a mage or have a single mage.) though the topic of this has been discussed to death.
What I wanted to ask was how do other ST's handle the numbers of supernaturals in their cities? Is it just as the plot demands or do you have a a thing like multiplying given number by 10 or do you make it so that every important city has enough of a population to represent every faction(Like every city has at least three of every clan or every tradition)?
