Key Facts: Number of megacities, urban areas with 10 million or more inhabitants has quadrupled from 8 in 1975 to 33 in 2025.

Jakarta is now the world’s most populous city, with nearly 42 million residents. The current population of Indonesia is 286 million.

In 2019, Indonesia said it will be moving its capital to Nusantara, a new city which is under construction.





To add some more detail regarding the new capital, Jakarta has some structural governance problems in the sense that it's very hard to improve infrastructure improve / stop the sinking of the city (mostly caused from over reliance on ground water pumping and permitting corruption / bad river management). Those problems might never be solved.

And separate of it's economic power it remains a center of power where the city mayor/governor always becomes a major national political figure.

Indonesia is actually a plurality of distinct island cultures, but with Jakarta, Java and Javanese culture sits at the top of the national political hierarchy. (Not to mention a sort of internal Javanese colonialism similar to the USSR).

The new capital could be part of dismantling some of the legacy internal Javanese power structures.

(To add a further detail re. Java vs. Indonesia, because of the mercator projection it's hard to see how big Indonesia is. It would stretch from Maine, past California almost to Anchorage).


New capitals also help prevent revolutions and uprisings. It's a lot easier to have a government that's insulated from the unrest of the masses, when everyone in its capital is loyal to it.

Some say the straight Paris boulevards were intended for cannon grapeshot ...

France had the inverse problem, all the nobles were sequestered away in Versailles, and weren't particularly interested in actually running the state.

I also imagine a lot of people who are admiring these megacities have never been to one. Jakarta has oceans of scooters and, when I was there to visit some customers with our country manager, she had a driver. With some exceptions like Singapore, SE Asian cities are horrible to get around.

Other than Singapore. I am not sure why SE Asian cities aren't going as all in on mass transit like China. Jakarta has a single subway line for 42 million people. They have some light rail line and buses. If you compare this with Tokyo, Shanghai, Beijing its really night and day.

The usual patterns that crop up are:

1) Lack of institutional knowledge. No one even knows how to get started and bringing in foreign expertise may be prohibitively expensive.

2) Economics don’t pencil out even in higher income countries compared to BRT systems, especially because high density and heavy traffic means the lines usually have to be grade-separated which adds additional costs compared to an at-grade system.

3) Corruption makes development impossible. No well-established processes for expropriation exist, or the country is given over to clientelism such that landlords won’t give up what they own and hamper the development process via political connections.

BRT is usually the most effective solution in places where grade-separated rail is not yet viable as it allows a right-of-way network to be established that can later be upgraded to rail. This doesn’t solve problem 3, which requires a comparatively authoritarian approach to overcome the incentive problems at play; this is why the Chinese have generally excelled in the space over the last 20 years.


For anyone interested in the issues with Indonesian economy, politics and development may I suggest a great book: Indonesia, Etc. by Elizabeth Pisani.

Even in the US, a lot of right-of-ways were taken by the government for rail and, later, highways (which intersected with earlier railroads in many cases) before it would have been as difficult a process as it would be today. Not a political comment so much as an observation that it's harder to just take private land today.

1) I really don't see how it prohibilitivly expensive. Much poorer places have built them and there are tons of companies who are willing to do it. Specially if you have a 30 year plan.

2) Another one I don't buy if you have a 30 year plan. Buses have higher operating costs, need more space, have less capacity and the surrounding infrastructure gets more expensive. The only thing BRT is good at, is making it easier to get start because you initially don't need ground infrastructure.

3) This is much more likely.

But Ill grant you what BRT might allow you do to is ban cars from a corridor without to many people being angry, and that is a win by itself.


> The only thing BRT is good at, is making it easier to get start because you initially don't need ground infrastructure.

The only thing rice is good at is being a cheap source of nutrition.


Nutrition is the point of eating, getting started isn't the point of public transport.

Any actual competent government cares about the long run, not just how fast to get started.

And even then, if you do a 'full' BRT its quite expensive. Its really just normal buses with some minimal priority that is much cheaper to get started.

And if you know its a route that eventually will have to get upgraded, its actually more expensive to first do the BRT and then upgrade.


The water table surely has something to do with it, but they could put much of it above ground like Bangkok does (erm, Bangkok should be listed as doing ok, even if they aren't doing as well as Singapore).

China built A LOT in the last 15 years. Beijing before 2008 had line 1, 2, a couple of suburban lines (13 and another one out east), and that was it. I don't think any other country has ever built infrastructure so quickly, so it isn't really fair to compare them to China.


That is a fair argument. China's level of infrastructure development is pretty absurd.

KL has subways. Even better is the KL city bus network which is free, air conditioned, and has free wifi. Despite Malaysia being a nominally muslim state, I found it multicultural and tolerant. If it wasn't for the heat and humidity, I'd consider it a great place to retire.

If you leave KL city and go to the surrounding areas, such as Petaling Jaya or Subang Jaya, it becomes more manageable (entering KL from there feels like a 5-10C temperature increase). It gets better the further you go of course, but for tourists that may be a bit tricky as it won't be as easy to get around (at least not without a car).

I was in KL for a business event. Can't say I cared for it much but it was just a few days. Didn't interact with public transit at all.

Did like Penang afterwards though.



Kuala Lumpur

Jakarta doesn’t have one metro line. It has 9 lines which it variously calls light rail, commuter trains, etc. but are metro lines in all but name, in terms of frequency, infrastructure, and service patterns. It’s not quite Beijing or Tokyo, but it’s also not as wealthy as either city.

Bangkok has built a lot of transit in the past decade, 6 lines on top of an already-substantial existing network. Still plenty of projects under construction as well. This alone puts it way ahead of Jakarta in terms of quality of life IMO.

It's a case of better late than never. KL has a reasonable mix of subway, monorail, elevated and suburban rail. Bangkok's above-ground BTS has been very popular and they have been building subways as well. Hanoi has a master plan and has opened its first subway line in 2021 and second in 2024. Manila is also digging subways right now and has wisely called in the Japanese to do it, given that city is simultaneously subject to typhoons, floods and earthquakes.

Probably a combination of overall wealth and government policies/stability/priorities. I'd probably add Hong Kong to the list of cities with pretty good public transit but, overall, it's pretty bad in that area of the world relative to cities that you'd generally consider to be "good."

Democratic governments are weak on deficit spending, especially poor ones, the debt from their tiny stretch of high speed rail almost became a scandal.

Infrastructure is expensive. It costs lots of resources and human labor and intricate planning (most SE Asia cities are not looking like anything there was planned).

Most countries on the planet simply cannot afford good infrastructure. I'm almost sure there's not even enough resources like energy and metals to create a good infrastructure in every country on Earth.


> I'm almost sure there's not even enough resources like energy and metals to create a good infrastructure in every country

As better public transport infrastructure vastly reduces the number of cars, and centralizes the requirement for both material and energy, I doubt that is the case. Buses and trains need far less of both than the population-equivalent number of cars/motorcycles.


Infrastructure is not only cars/buses. It is also: roads (paved roads), electricity lines, water pipes, bus stops, traffic lights (you won't find many traffic lights in SEA countries), train stations, railroads, etc.

It's evident if you live for several months in almost any SEA city, that they lack even basic infrastructure. I'm sure it's not only matter of negligence, they simply cannot afford many things that people in developed countries see as granted.


I agree on the difficulty of distribution of resources, just not the idea of there being a lack of them. Maybe not relevant for any practical purposes.

> I am not sure why SE Asian cities aren't going as all in on mass transit like China

Eminent domain and mass demolitions were very common in 1990s-2010s China, and to a degree that I have not seen in other authoritarian and nominally communist states like Vietnam or even Laos, let alone other less authoritarian states.

Entire neighborhoods, villages, and towns were razed to build the urban areas that make up China today.

Beijing [0][1], Shanghai [2][3], and other cities across China [4] all saw massive urban demolitions until the Central Government banned them in 2021 during the Evergrande crisis [5] due to limited utility and rising urban discontent.

Back in the day, it was somewhat common to see news about some random Jie commiting a terrorist act in retaliation for being evicted from their homes [6][7] due to this urban demolition program, and partially helped Xi consolidate power as most officials affiliated with these programs were deeply corrupt, and were often felled during the anti-corruption purges (ironically, Xi oversaw similar initiatives in Zhejiang in the 2000s).

Most other governments don't see the utility of implementing a similar style of program.

In Beijing alone, some activists said more than 1 million people were forced from their homes to make way for new sports venues for last year's Olympics.

Wow...


And, while you can pick and choose data, Beijing's Olympic stadium is not really very widely used as far as I can tell. Of course you can also debate whether a lot of urban revitalization projects--even if leading to popular settings/venues--were worth the cost to neighborhoods that were basically flattened.

And don't forget Beijing's forced eviction of tens of thousands of so called 'low end population' in the middle of winter.

Even in democratic Taiwan they have this mindset to an extent - private land must not stand in the way of infrastructure.

Taiwan's mass urban demolition spree happened towards the tail end of authoritarian rule, and did in fact play a role in garnering mass support for the democracy movement.

After democracy, Taiwan shifted towards trying to preserve traditional neighborhoods or working to normalize unofficial neighborhoods and slums - basically adopting a bottom up instead of top down approach [0]

Or electric bikes and cars

For electric vehicles, in third world countries the most obvious bottlenecks are pricing and infrastructure. However despite that, I'm quite surprised by how fast adoption actually is even when it's not as fast as first world countries.

For bikes, we already have TON of powered bikes. I can actually see electric bikes opening the eye of Americans on the wonder of scooters.


Everytime I see the ocean of scooters, I wonder how horrible it'd be if scooters weren't invented but instead everyone use cars like in America. Either it'll make the most legendary traffic jam ever or GDP will be cut in half since no one can move anywhere. With our already overcrowded public transport, it's practically the only alternative.

I actually wonder how much better American traffic would be if scooters are more popular.


The Netherlands had over 1000KM (621 miles) of traffic jams Monday morning.

Americans use cars because we can afford them. The Indonesians would too if they could.

Most Dutch people can afford cars, but many are on bikes (including cargo/e-bikes), about 27% of all "movements" [0]. This is because of the way our infrastructure is set up, the bike is very often optimal (special bike lanes, shorter routes, better/free parking at destination or public transport hubs). Most people do own a car though.

True, but if there was a city of 40 million in the Netherlands, I'm afraid very few would venture out on bikes there too.

It would be subways then, not cars I suspect. At least in a city like Rotterdam (673K inhabitants) that is by far the optimal way to get around, cars are really almost useless in the city center.

Here, most of the street is already reserved for bikes, with the sidewalks for pedestrians [0]. This is all a one way street.

I can't find the link anymore, but aeons ago I read a blog post on here claiming that the Netherlands is better characterized as a city state, if you're looking at it from an American point of view: the entire country is about the same size as NYC's metro area, and around the same population.

Car ownership correlates negatively with urbanization in NL, so no, I don't think so. And no 40M city (or 4M city) convinces me driving is an acceptable way to get around.

How would Indonesians use cars that cannot go anywhere? It's not about affording but about people/m² compression.

Here's a quick napkin math: a 1.3m² scooter can take 1-3 people, a toyota camry of 8.8m² can take 1-5 people. This gives the humble scooter aprox 3-5 times the space efficiency that of a car.

Not to mention the agility and parking benefits of scooters. There's no way any SEA city could get rid of scooters in favor of cars. Scooters are incredibly under-rated in the west and my favorite tool here in SEA - it's peak practical engineering at scale.


That makes sense, but I have to assume driving a scooter is a pretty dangerous way to get around a giant city?

I have biker friends who call cars "cages", and I get the sentiment. But they have a lot more concussions than any other group of people I know.


I agree with other commenter and speed is primary danger for scooters. I've been driving for 7 years (mostly in Thailand) and never had an accident as the risk distributions is incredibly obvious:

- stay within reasonable speed

- keep distance

- don't do highways

- project your intentions very clearly with no sudden moves

vast majority of accidents happen when this simple rule set is broken (aside from obvious DUI). If you're driving 40km/h max in a city you are surprisingly safe, especially as scooter traffic culture is very river like so once you're familiar with the area you are basically being carried by the traffic.

Most stats of SEA scooter deaths are coming from really bad driving, as in drunk uncle driving a scooter on the opposite side of the road with no headlights sort of bad driving (sadly very common). The culture can be very unserious about scooter safety when it's quite achievable in practice. It really is an incredible form of transportation when taken seriously.


Since this is scooters who rarely even reach >150cc, it's actually quite safe since it's slow and light. There are always high risk when we want to go to very rough roads that are also full of trucks (common in rural areas), but in well maintained roads like lots of Jakarta, it's mostly fine.

Though it really isn't helped by attitude of people around here who aren't even wearing helms.


Americans use a car because their infrastructure was build to support it. If they had cities like exist in South East Asia they wouldn't use it. Because if they did it would literally be no traffic, because the city would barly move and you wouldn't get anywhere.

These cities already have to much traffic while only a small number of people have cars.


I got curious to see how many people have cars in Jakarta. While cars per capita of Indonesia is extremely low (~80 / 1000 people), the one for Jakarta is at respectable ~300/1000 people, not far from NYC at ~400/1000 people. Still far away from other cities though.

From my experience also, scooter is still heavily used even by people that have cars because there's just a lot of small roads and neighborhood where it's very unsuitable for cars. This also makes scooter taxi very popular here since it's cheaper, faster, and can reach the deepest parts of Jakarta.


Hehe. Great point. I have lived and worked in 2 Delhi and Mumbai in India. With such terrible living condition, traffic, pollution and so on it sucked the soul out of me. At least I found it so bad in Mumbai that many a times while leaving from work to hostel, I would literally cry on train platform with massive crowd pushing and shoving from all directions while trying to get into bursting at seams trains.

And this all is 20 years back. During this time thing have gone worse many times over.


I’ve liked living in Delhi recently, much less congested than Bengaluru that gnaws on my soul with its insane traffic. The only reasonable way to live in India is to live away from the main streets, ideally in a gated community which is a bikeable distance from work.

> In 2019, Indonesia said it will be moving its capital to Nusantara, a new city which is under construction.

Because Jakarta is literally sinking into the ocean. It also has a terrible flood problem which is only going to get worse. Doesn’t bode well for the population.
