It's that time of year again.
Monocle has just released their annual Quality of Life Survey. This is their 18th annual ranking of the world's top cities according to what they do best: whether it be housing or nightlife. What I like about this survey is that it does things a little differently. Most liveability surveys tend to be a list of the world's most boring cities. It's as if uneventfulness is the measure of quality of life.
This is not that.
For example, number 3 on the list is Athens. And it's there specifically because of its nightlife. Monocle refers to it as "one of Europe's few truly 24-hour cities." Also on the list, at number 7, is Mexico City. This is a city that is required to have women-only subway cars because the men apparently can't behave in public.
Of course, it's an incredible city in so many other ways. It has leafy neighborhoods filled with the kind of mid-rise buildings that Toronto is now desperately trying to add to its major streets. And according to the survey, the city's population grew by about 600,000 people between 2019 and 2023 — many of whom came from the US and Canada.
Jumping to the top of the list, Monocle's city of the year and best all-rounder is a city that we talk a lot about on this blog: Paris. This is perhaps not surprising given the city's bold moves to pedestrianize streets, plant trees everywhere, build more than 1,000 km of bike lanes, and generally enhance the overall urban experience.
But it's not just that:
All of this, combined with the policies of the country’s most pro-business president in a long time, has helped Paris to draw and foster enough talent to snatch London’s double crown as Europe’s top venture-capital city and its leading technology hub. “Paris lends itself far more to an office-based culture than cities such as San Francisco or London,” says Jordane Giuly, the founder of fintech company Defacto. He points out that the French capital’s gentle density is conducive to cross-pollination between start-ups and preferable to the vast distances that one needs to traverse in its rivals.

I have a new not-so-serious goal. I say not-so-serious because I'm busy with lots of other things and who knows if/when I'll actually get around to this. So let's just say that this goal is based on a strong interest. I would like to visit the 10 largest urban areas in the world.
I was careful to say urban areas, because largest cities can be misleading. City proper boundaries are an arbitrary measure. What matters more are the built up areas.
I have already been to a handful of them, namely the ones centered around Tokyo, Dhaka, and Mexico City. But there are more on the list that I haven't been to.
There are, however, two immediate challenges with setting a not-so-serious goal like this one. The first is that it's not easy to come up with a definitive list of the largest urban areas. It's nuanced and, for some cities, population estimates are very much rough estimates.
The second is that population figures are constantly changing. So by the time I get around to this, many of the largest cities might be in Africa (current forecast for this century) and I may be checking off the wrong list.
But let's not let perfect be the enemy of good. Here's what I came up with. And by "what I came up with," I mean that I asked ChatGPT its opinion. This is the list I got:

Then I asked the question in a slightly different way and got this list:

Then I asked it to tell me its definition of metropolitan area vs. urban agglomeration:

Finally, I asked it why Lagos, Nigeria was not on the list. Current estimates place this urban region at more than 20 million people (which would place it ahead of New York in the first list), but I don't think anyone really knows for sure. Whatever the current number, it is widely understood to be one of the fastest growing city regions in the world. This is how ChatGPT responded:

I'm a little torn because high on my list of cities to visit are São Paulo and Seoul. And they don't seem to be finding themselves on the same list. I'm also very curious to see Lagos, and I have a suspicion that it's much larger than official estimates. Regardless, there are some clearly big cities to check off. India and China would be good places to start. So I better get to work. Or not. Since this is a not-so-serious goal.

Mexico City is all kinds of big. It is the largest metropolitan area in North America, the largest Spanish-speaking city, and broadly one of the largest megacities in the world. Because of this, it can be, you know, hard to move around.
I remember visiting the city for the first time when I was in elementary school, and it standing out to me that everyone had one day of the week when they were simply not allowed to drive their car. It was/is a form of load balancing. Imagine that. (I don't know if this is still the case, or if it's even more stringent today.)
I also remember visiting the city later on, when I was in grad school, and it standing out to me that their metro had women-only cars. This was and continues to be an attempt to try and minimize the amount of sexual harassment that takes place on transit. Again, it can be hard to move around Mexico City.
The city's latest solution is one that has found success in other Latin American cities, such as Medellin, and that is: cable cars. Relative to subway or light rail, they're inexpensive. They're also good at navigating steep terrain, and their stations can be inserted into dense urban areas. This includes working-class neighborhoods who might otherwise have very limited mobility options.
For reasons like these, Mexico City has spent the last three years building three new cable car lines, the most recent of which opened just last month. The city now has the longest cable car line in the world. But more importantly, it has a new transit add-on that is moving up to 80,000 people per day.
This isn't as much as rail. But that's okay. The point of these lines is to bring more people closer in so that they can then connect to more services and other mobility options. And to do it quickly. Three new lines in three years is impressive. And from the sounds of it, it has transformed many people's lives for the better.
Here are maps of the 3 lines, zoomed out a bit so that you can see how they fit into the city's broader urban context:
