Paris is a high-density city by Western standards. It's either the highest-density city in Europe or close, depending on how exactly you demarcate cities. We often have discussions here about how San Francisco needs to densify, but Paris has 3x the population density of SF, so is nowhere near in the same league of low-density cities. It's 50% denser than Brooklyn. Of American cities / sub-city regions, only Manhattan edges it out (Manhattan is 30% more dense).
