When it comes to cities, quality of life is a subjective measure. Some people may prefer a small city where homes are more affordable and commute times are negligible, while others may find the unique amenities of a big city more appealing — enough to outweigh the negatives.

Whatever the exact case, there are some obvious negatives that come with urban scale. The usual suspects are high housing costs, traffic congestion, noise and pollution, crime and safety concerns, and the list goes on. But is it universally true that quality of life has to decline as a city grows?

I don't think so at all. I wasn't able to find a good primary source on this topic, but the obvious example and outlier that comes to mind is Tokyo. It is both the largest metropolitan area in the world and a city that consistently ranks near the top of most quality of life indices.

So how do they do it?

There are lots of ingredients that go into a city like Tokyo, but I would argue that one of if not its most important, is its transit network. Tokyo has one of the highest rail modal splits and one of the lowest driving rates in the world. And it's the only way a city of this scale could actually function as efficiently as it does.

This is not me being an ideologue (which I am sometimes called); it is me being a pragmatist. Show me a big global city with more than 10 million people that is oriented around the car and does not have a traffic congestion problem, and I'll happily change my mind.
