Interesting to get any insight into that area.
Just out of interest ancient Rome had a population of 0.073 per square meter in 100 AD (according to google AI) and Athens 0.025 per square meter. (5th century)
So 10,000 square meters gives a population of between 250 and 730. This does rather redefine the term city :)
I think one would assume that there would be a larger rural population living outside the walls. Indeed given the disease risks due to cramped conditions and lack of plumbing, we'd probably see the traditional situation where the urban population was kept up by migration into the city from outside.
