Chinese here. Off top of my head, with about the same area of land, divided by about 5x more population, let's say about 5x time denser? Personally, I grew up in a "small town" with about 100,000 people, we call it a small town because relatively, it IS a small town. I do not have any statistics to back it up, but the density level of that third-level township feels to me to be higher than Brooklyn NYC.
