OK, thanks guys that helps. The maps are good, btw, I hadn't seen these before. There are many more sectors than I'd imagined.
It all makes me think there must be a lot more open space in the city than I'd previously imagined - if there are between 4000 and 6000 blocks spread over such a large area. I guess I'd always been led to believe from the artwork that the whole city was just crammed full of blocks, and open space was a rare luxury (wasn't there a sort of fabled, hidden garden or park area that's appeared in one or two stories?). Maybe it's mostly undeveloped and undesirable wasteland - huge landfill sites or something. I guess also there are other buildings besides residential blocks.
