> It seems like what you're describing is more an artifact of where we choose to draw city boundaries than that Paris actually is denser in practical terms as experienced on the ground.

I mostly agree, but it's important to note that Paris is a lot smaller than NYC, so comparisons between NYC boroughs (which are each almost as big as the city of Paris) and Paris' surrounding departments are clearly favorable for NYC.

If you compare cities of similar size, i.e. Paris with Los Angeles (which is still bigger, both city and metro area), then the european capital is significantly ahead in density (and I did not cherry pick Los Angeles specifically, it's the same for Chicago, Houston, etc.), and the difference is very significant: Even the core of those US cities (excepting NYC) is less dense than the 3 inner Parisian suburb departments (!!).

Isn't that just another way of saying that they drew the city boundaries differently than they did in NYC? If you extend the boundaries out to the 814 km^2 of Greater Paris, that gives it a fairly similar population to NYC (7m compared to 8.8m) with a very similar area (814 km^2 to 778 km^2).

My point is that the conditions at those boundaries are not comparable: Greater Paris is pretty much a whole metropolitan area, which is "non-urban"-ish at the boundaries. If you take a slice out of NYC with the same population/area, then that is still only a part of a (bigger than Greater Paris) metro area of like 20M people...
