Yep. I assume the dragons live more on the left half, further from the big city and humans near the river. But like Josh said (I think) there are dragon aristocrats and stuff who support and help the humans and vise-versa for more poor-type humans.I think there is a side of the city that is mostly human population and a side that is mostly dragons. The human side, I assume, is closer to the shipping port that is built on the river, which is where King's breakout occurred.
There are Nightwing soldiers that patrol the city from what I've learned from MJ, so I assume it's mostly run by humans
