I did some reading on Paizo myself, after I read your post. For the most part, I'll agree. More people, with less space, in town. Generally speaking, back then, a large number of people still lived rurally.

Obviously I'm not going to go block by block, counting each house as 5 people, or whatnot. Some parts would definately be more crowded, like the poor quarter >.<

I noticed alot of city maps that don't include any sort of warehouse district. Being an area of high trade, I would expect some largish buildings near the docks, where trade could be stored while its awaiting transfer or pickup or whatever. Is that unreasonable?

Apologies if I'm rambling. When I'm stuck on something I tend to ramble. ;-)
