I imagine Khromarium as roughly equivalent to Dark Ages Rome- a metropolis that once supported a million+ people reduced to 30,000 souls and maybe another 10% of transients and destitutes. The bourgeoisie of Khromarium use professional guards and marines (mercenaries) to protect their enterprises. The noble households can raise knights and men-at-arms in time of war. The city watch are unpaid volunteers organized by neighborhood and led by a prominent citizen. They mostly watch for fires and call out the hours but can be mobilized en masse into a sizeable militia force in times of great need. Villages and towns have a volunteer militia augmented and led by the household of local lords, perhaps a knight or two and a handful of men-at-arms in the smaller settlements. 

For the sake of simplicity, I rule that men under arms typically represent .5-1% of total population in peace time and up to 10% in time of war.  With these numbers you should be able to extrapolate answers to the rest of your questions.

I respectfully disagree that Swampgate is in any way typical. It is a highly militarized town, the last bulwark protecting Khromarium from the barbarian hordes. With a population of 1.010 and 228 of them under arms I'd say Swampgate is on a war footing. There's an additional 96 soldiers from Khromarium plus 43 rangers that Swampgate has to somehow support. The cost of sustaining all those people who don't grow food in a Dark Age society would be immense.

The way I see it, Khromarium is providing troops and construction materials to Swampgate in exchange for all that peat and bog iron they're taking out of the area.  Those logs for the perimeter wall likely didn't grow locally, and I doubt they were cheap.  One more source of tension between the City and the locals.
