Mapping the World’s New Megacities in 2030
The Chart of the Week is a weekly Visual Capitalist feature on Fridays.
Rapid urbanization is one of the major forces shaping our global economic future.
A century ago, it was almost unfathomable that any person would want to live in a city with 10 million other people, but by the 1930s, New York City was the first metropolitan area to pass the mark. Fast forward to today, and there are 33 urban areas that meet the definition of a “megacity” spread throughout the globe.
It’s true that many of these megacities have been global centers for a long time – think cities like London, Tokyo, Los Angeles, and Paris – but we are now entering an era in which new megacities are cropping up every other year, including ones that have less familiar names and backstories.
The Megacity Landscape
Today’s chart is based on a forecast from Euromonitor International, outlining how the megacity landscape will shift in the coming years.
It focuses on the 39 megacities expected by the year 2030, when they will house 9% of the global population and contribute 15% of the world’s GDP. These same megacities will take up about 3% of global land mass.
New Megacities by 2030
Just over a decade from today, there will be five new megacities in developing countries, and one from a developed market:
The Windy City has been on the cusp of the megacity mark for some time, and it will finally hit 10 million inhabitants in the coming years. In 2030, it will have by far the biggest GDP of all new megacities, at $596 billion (constant 2017 prices).
The high-altitude Colombian capital will join the ranks of other Latin American megacities like Rio de Janeiro, São Paulo, Mexico City, Lima, and Buenos Aires. It will have a $109 billion economy (constant 2017 prices) by this time.
This is the entry to the list with the fastest-growing population. Between 2017-2030, the city will increase its residents by 60% – but it will still be nowhere as big as Cairo, which will be Africa’s biggest megacity at 29.8 million people.
This city, which is on the Bay of Bengal in eastern India, will be the most dense of all new megacities by 2030. Chennai’s economy, however, will be $50 billion (constant 2017 prices) – which is just 1/12 the size of Chicago’s.
Iraq’s biggest city already has close to 8 million inhabitants, but by 2030 it will get to the double digits thanks to its impressive population growth rate.
Dar es Salaam
The most populous city in Tanzania is growing almost as fast as Luanda – and on top of that, it has the fastest-growing (and smallest) GDP of the six new megacities. This isn’t the first time the city’s name has come up in a projection like this, as the Global Cities Institute sees it being the third most populous city in the world further down the line.
What other interesting things are projected to happen to key urban centers?
- Jakarta is anticipated to be the biggest megacity of all in 2030 with 35.6 million people
- Tokyo will fall from the top spot, as an aging population translates to negative population growth
- Osaka will be the oldest megacity with 31% of the population aged 65+
- Lagos will be the fastest-growing city overall in the 2017-2030 timeline
- Roughly a dozen cities will double their economies over this timeframe, led by Dhaka, Manila, and Bangalore
When it comes to global urbanization, the only constant is change – and massive metropolises that seem unfathomable today could be much more commonplace down the road.
The Best and Worst Performing Wealth Markets in the Last 10 Years
This telling chart shows how national wealth markets have changed over the past decade, highlighting the biggest winners and losers.
The Best and Worst Performing Wealth Markets
A lot can change in a decade.
Ten years ago, the collapse of Lehman Brothers sent the world’s financial markets into a tailspin, a catalyst for years of economic uncertainty.
At the same time, China’s robust GDP growth was reaching a fever pitch. The country was turning into a wealth creation machine, creating millions of newly-minted millionaires who would end up having a huge impact on wealth markets around the world.
The Ups and Downs of Wealth Markets (2008-2018)
Today’s graphic, using data from the Global Wealth Migration Review, looks at national wealth markets, and how they’ve changed since 2008.
Each wealth market is calculated from the sum of individual assets within the jurisdiction, accounting for the value of cash, property, equity, and business interests owned by people in the country. Just like other kinds of markets, wealth can grow or shrink over time.
Here are a few countries and regions that stand out in the report:
Developing Asian Economies
In terms of sheer wealth growth, nothing comes close to countries like China and India. The size of these markets, combined with rapid economic growth, have resulted in triple-digit gains over the last 10 years.
For the world’s two most populous countries, it’s a trend that is expected to continue into the next decade, despite the fact that many millionaire residents are migrating to different jurisdictions.
European nations saw very little growth over the past decade, but the Mediterranean region was particularly hard-hit. In fact, eight of the 20 worst performing wealth markets over the last decade are located along the Mediterranean coast:
|Rank (Out of 90)||Country||% Growth (2008-2018)|
European Bright Spots
There were some bright spots in Europe during this same time period. Malta, Ireland, and Monaco all achieved positive wealth growth at rates higher than 30% over the last 10 years.
While it’s expected to see rapidly-growing economies as prolific producers of wealth, it is much more surprising when mature markets perform so strongly. Singapore and New Zealand fall under that category, as does Australia, which was already a large, mature wealth market.
Australia recently surpassed both Canada and France to become the seventh largest wealth market in the world, and last year alone, over 12,000 millionaires migrated there.
The long-term economic slide of Venezuela has been well documented, and it comes as no surprise that the country saw extreme contraction of wealth over the last decade. Since war-torn countries are not included in the report, Venezuela ranked 90th, which is dead-last on a global basis.
Short Term, Long Term
In 2018, global wealth actually slumped by 5%, dropping from $215 trillion to $204 trillion.
All 90 countries tracked by the report experienced negative growth in wealth, as global stock and property markets dipped. Here’s a look at the wealth markets that were the hardest hit over the past year:
|Wealth Market||Wealth growth (2017 -2018)|
The future outlook is rosier. Global wealth is expected to rise by 43% over the next decade, reaching $291 trillion by 2028. If current trends play out as expected, Vietnam could likely top this list a decade from now with a staggering 200% growth rate.
Mapping the World’s Busiest Air Routes
Flying can get you almost anywhere, but often people are journeying between two popular destinations. Here we map the busiest air routes globally.
Mapping the World’s Busiest Air Routes
Modern air travel gives us almost unlimited possibilities for getting around.
Whether you are acting on your wanderlust to explore new and exotic destinations, hopping to a familiar island for a well-deserved vacation, or jetsetting to London in the comfort of business class, the modern airline industry can get you almost anywhere you need to go.
But while flying allows us to have unique experiences, it’s often the case that we are all coming and going from many of the same popular destinations. As a result, the world’s busiest air routes have hundreds of flights per day connecting important city pairs together.
Ranking City Pairs
Today’s chart pulls data from OAG, which has compiled a detailed report ranking the busiest domestic and international air routes from around the globe.
It’s worth noting that the data is over the period of March 2018 to February 2019, and it excludes carriers that operate fewer than 500 routes per year.
Let’s dive in to see which city pairs have the most air travel between them.
Domestic routes are far more popular than international routes globally. According to the report, there are 15 domestic routes that have more operating flights per year than any international route anywhere.
Here’s a look at the top 10 domestic routes:
|Rank||Country||City Pair||Flights (Annually)||Carriers|
|#1||🇰🇷||Jeju ↔️ Seoul||79,460||7|
|#2||🇦🇺||Melbourne ↔️ Sydney||54,102||4|
|#3||🇮🇳||Mumbai ↔️ Delhi||45,188||6|
|#4||🇧🇷||São Paulo ↔️ Rio de Janeiro||39,747||3|
|#5||🇯🇵||Fukuoka ↔️ Toyko||39,406||4|
|#6||🇻🇳||Hanoi ↔️ Ho Chi Minh City||39,291||3|
|#7||🇯🇵||Hokkaido ↔️ Tokyo||39,271||4|
|#8||🇮🇩||Jakarta ↔️ Surabaya City||37,762||6|
|#9||🇺🇸||Los Angeles ↔️ San Francisco||35,365||5|
|#10||🇸🇦||Jeddah ↔️ Riyadh||35,149||5|
The busiest domestic route might be a surprise, unless you are familiar with Asian geography.
With almost 80,000 annual flights, the 300-mile hop between Seoul and Jeju Island in South Korea is the busiest air route in the world by a large margin. Overall, there are seven carriers competing on it each day, with over 200 daily flights available between them.
What makes Jeju so popular?
Known as the “Hawaii of South Korea”, this volcanic island is an extremely popular vacation destination within the country, and it hosts roughly 15 million guests per year.
On an international basis, the busiest route has almost 50,000 fewer flights per year than the Jeju-Seoul city pair listed above. Not surprisingly, this route – and many other top international routes – are also located in the Asia Pacific region.
|Rank||Countries||City Pair||Flights (Annually)||Carriers|
|#1||🇲🇾🇸🇬||Kuala Lumpur ↔️ Singapore||30,187||8|
|#2||🇭🇰🇹🇼||Hong Kong ↔️ Taipei||28,447||5|
|#3||🇮🇩🇸🇬||Jakarta ↔️ Singapore||27,046||7|
|#4||🇭🇰🇨🇳||Hong Kong ↔️ Shanghai||20,678||5|
|#5||🇮🇩🇲🇾||Jakarta ↔️ Kuala Lumpur||19,741||8|
|#6||🇰🇷🇯🇵||Seoul ↔️ Osaka||19,711||8|
|#7||🇺🇸🇨🇦||New York (LGA) ↔️ Toronto||17,038||3|
|#8||🇭🇰🇰🇷||Hong Kong ↔️ Seoul||15,770||9|
|#9||🇹🇭🇸🇬||Bangkok ↔️ Singapore||14,698||5|
|#10||🇦🇪🇰🇼||Dubai ↔️ Kuwait||14,581||4|
The short hop between Singapore and Kuala Lumpur takes only one hour, and it connects two major Southeast Asian commercial hubs. The route has 41 flights per day between eight airlines, making it one of the most competitive routes globally.
The busiest international route outside of the Asia Pacific is between Toronto and New York (LaGuardia) with 17,038 annual flights. Interestingly, it only has three competing carriers – the lowest of any of the top 10 routes.
