I know I know this, but this is still an alarming chart:
This is saying that, as of 2016, over 36% of Americans were considered to be obese. In Canada, the number was just under 30%. And in the UK, it was just under 28%, which is the highest rate in Europe.
We often talk about the health benefits of living in a walkable community. And there's lots of research to back up that this is in fact the case: obesity rates tend to be inversely correlated with higher prevalences of active transportation (walking, cycling, and so on).
But we also can't ignore diet. And here's what has happened in the UK, as well as in other Western countries:
An increased reliance on cheap, ultra-processed food, which accounts for 57 per cent of what Britons eat according to a 2019 study conducted by researchers at the University of São Paulo, suggests that the health crisis is unlikely to change anytime soon without intervention, argue campaigners.
It can be hard to eat healthy, especially if you don't have a lot of money and you live a busy life. But in my view, we need to change the course of this graph. And two very good places to start looking would be (1) our built environment and (2) the Japanese diet.
Actually, now that I think of it, Japanese cities would be a good place to look as well.

Azeem Azhar's recent newsletter, titled "Don't call time on the megacity: cities will learn and adapt," is a reminder of the tensions that cities face. There are forces of attraction. And there are also forces of repulsion.
Cities all around the world continue to create wealth and lift people out of poverty. But they also repulse people through traffic congestion, housing supply shortages, and overcrowding (which is distinct from density). Generally though, the forces of attraction have tended to outweigh the forces of repulsion, which is why the world continues to urbanize.
As Azeem points out, the first city believed to have reached 1 million inhabitants was Rome. It happened some 2,000 years ago. In the 1930s, New York then became the first city to reach 10 million inhabitants. And today, the 10 largest urban agglomerations in the world look something like this:

Outside of Japan, all of these city regions are expected to add many more people by 2030. Missing from this chart, however, are cities such as Lagos, Nigeria. Between 2018 and 2050, the UN estimates that 35% of the growth in the world's urban population will come from just three countries: India (+416 million), China (+255 million), and Nigeria (+189 million).
Long live the megacity.
