France already has some of the most densely populated cities in the world, Paris is #32. French cities feel less congested than the likes of US cities because it has better cycling infrastructure and public transport options. High population density is not a cure for the bias car infrastructure imposes on a city. So your recipe will need to take more in to account than just density.

But why are French cities so densely populated? The country is twice the size of the UK with roughly the same population.

There was a semi-arbitrary building height adopted during the Haussmannian reorganization in Paris. My feeling is people noticed it led to perfectly liveable blocks. (Most places go a bit higher than this by now but Paris is strongly attached to the "roofs of Paris" and actively protects them. So Paris is a mix of Haussmannian building heights and higher.)

In the 50es through 70es, there was a strong need for extra housing which led to the projects outside Paris ("citées"), to many factories torn down to make space, but also to much higher residential buildings here and there. Still worked fine (well, not many of the citées worked fine).

And people really, but REALLY love being able to walk to their preferred local baker and pastry shop (out of a choice of several of course), and to the local grocery store. The density has to be high enough to support these.

Turns out, high density also allows a great subway system. Nobody complains that it exists.

How does that linked Wikipedia page not contain any cities in China, which in my experience are more dense than just about anywhere else in the world?

[bobthepanda]

one is that Chinese "city" boundaries also generally include a lot of rural land, mountains, etc. Chongqing is the size of Austria.

The other is that while the buildings are certainly tall, China also does a lot of "tower-in-the-park" style development where the plazas and landscaping in between tall buildings decrease overall density.

PRC cities are not particularly dense. Population densities in cities within a country tend to follow zipfs law, which would predict BJ and SH to be 3-4x larger than it currently is. Many economists and urban planners was suggesting PRC should densify tier1 about 10 years ago. But hukou anbd industrial policy seems to be designed to limit megacity sizes to redirect popuation towards growing 3rd, 4th+ tier cities into their own economic hubs. IMO trying to avoid SKR/JP where everyone rushes to a few economically viable regions.

China is deurbanizing and dedensifying. It's a popular myth that Chinese cities are dense. Density peaked a decade ago.

This will spell economic worries someway down the road as maintenance upkeep costs start to kick in.

What is your experience ? China cities are noticeably less dense than other cities in Asia (Manilla, Delhi..) or even Paris

[resolutebat]

Most of Manila is an endless sprawl low-rise housing and single-story slums, with a few areas of high-rise buildings (Makati, BGC, etc). In the average large Chinese city, more or less all the housing is high-rise.

[bobthepanda]

how much of that housing is occupied vs investment, and how large are the apartments? slums get quite packed.
