Ranked: The Megaregions Driving the Global Economy

If you’ve ever flown cross-country in a window seat, chances are, the bright lights at night have caught your eye. From above, the world tells its own story—as concentrated pockets of bright light keep the world’s economy thriving.

Today’s visualization relies on data compiled by CityLab researchers to identify the world’s largest megaregions. The team defines megaregions as:

  • Areas of continuous light, based on the latest night satellite imagery
  • Capturing metro areas or networks of metro areas, with a combined population of 5 million or higher
  • Generating economic output (GDP) of over $300 billion, on a PPP basis

The satellite imagery comes from the NOAA, while the base data for economic output is calculated from Oxford Economics via Brookings’ Global Metro Monitor 2018.

It’s worth pointing out that each megaregion may not be connected by specific trade relationships. Rather, satellite data highlights the proximity between these rough but useful regional estimates contributing to the global economy—and supercities are at the heart of it.

From Megalopolis to Megaregion

Throughout history, academics have described vast, interlinked urban regions as a ‘megalopolis’, or ‘megapolis’. Economic geographer Jean Gottman popularized the Greek term, referring to the booming and unprecedented urbanization in Bos-Wash—the northeast stretch from Boston and New York down to Washington, D.C.:

This region has indeed a “personality” of its own […] Every city in this region spreads out far and wide around its original nucleus.

Gottmann, Megalopolis (1961)

By looking at adjacent metropolitan areas rather than country-level data, it can help provide an entirely new perspective on the global distribution of economic activity.

Where in the world are the most powerful urban economic clusters today?

The Largest Megaregions Today

The world’s economy is a sum of its parts. Each megaregion contributes significantly to the global growth engine, but arguably, certain areas pull more weight than others.

Altogether, these powerhouses bring in over $28 trillion in economic output.

Unsurprisingly, Bos-Wash reigns supreme even today, with $3.6 trillion in economic output, over 13% of the total. The corridor hosts some of the highest-paying sectors: information technology, finance, and professional services.

The largest city in Brazil, São Paulo, is the only city in the Southern Hemisphere to make the list. The city was once heavily reliant on manufacturing and trade, but the $780 billion city economy is now embracing its role as a nascent financial hub.

On the other side of the world, the cluster of Asian megaregions combines for $8.7 trillion in total economic output. Of these, Greater Tokyo in Japan is the largest, while Shandong might be a name that fewer people are familiar with. Sandwiched between Beijing and Shanghai, the coastal province houses multiple high-tech industrial and export processing zones.

The data is even more interesting when broken down into economic output per capita—Abu-Dubai churns out an impressive $86,200 per person. Meanwhile, Delhi-Lahore is lowest on the per-capita list, at $14,946 per person across nearly 28 million people.

Where To Next?

This trend shows no sign of slowing down, as megacities are on the rise in the coming decade. Eventually, more Indian and African megaregions will make its way onto this list, led by cities like Lagos and Chennai.

Stay tuned to Visual Capitalist for a North America-specific outlook coming soon, and a deep dive into the biggest factors contributing to the growth of these megaregions.

Global Shutdown: Visualizing Commuter Activity in the World’s Cities

Amid the COVID-19 crisis, cities are dramatically slowing down. Today’s chart demonstrates the impact of lockdowns on commuter activity worldwide.

Published

on

Staying Put: The COVID-19 Commuter Decline

Every day, millions of people worldwide rely on public transport networks to get around. But in times of crisis, bustling cities with high volumes of commuter traffic can come to a dramatic halt.

Today’s chart breaks down daily data from Citymapper’s Mobility Index, according to trips planned on the transport app across 41 select cities.

The results paint a unique picture of how social distancing and lockdown measures are impacting commuter and economic activity in major urban hubs.

Cities With the Biggest Drops in Activity

As the government response to the COVID-19 pandemic intensifies and people are urged to stay home, transit activity is dropping everywhere.

However, some areas are seeing more of a reduction in activity than others. Where has activity declined the most over the month?

RankCityCountry04-Mar11-Mar18-Mar25-MarTotal Change (%)
#1Vienna🇦🇹 Austria128%92%9%6%-122%
#2Lisbon🇵🇹 Portugal128%108%24%12%-116%

#9Los Angeles🇺🇸 USA108%81%23%13%-95%
#10Melbourne🇦🇺 Australia113%110%53%20%-93%

*Note: Data measures the % of city moving compared to 100% baseline.

Overall, Vienna and Lisbon are the cities with the biggest average drop in commuter activity over the past few weeks. This decline in mobility is correlated with a spike in the proportion of COVID-19 cases in the population:

  • Austria
    March 4: 2.6 per million
    March 25: 586 per million
  • Portugal
    March 4: 0.4 per million
    March 25: 232 per million

That said, not every city is seeing a precipitous decline in activity — let’s look at those next.

Standing Still, or On Guard

Cities that saw lower decreases in commuter activity over recent weeks can generally be slotted into three categories:

  1. Cities that were already on or near shutdown (Seoul, Milan)
  2. Cities that have so far avoided major impacts from the virus (St. Petersburg)
  3. Cities that successfully mitigated spread (Singapore)

Here are the 10 cities on the list that saw the lowest changes in activity:

RankCityCountry04-Mar11-Mar18-Mar25-MarTotal Change (%)

#9Stockholm🇸🇪 Sweden97%83%34%32%-65%
#10Lyon🇫🇷 France75%97%6%4%-71%

*Note: Data measures the % of city moving compared to 100% baseline.

St. Petersburg is still seeing commuter activity at 69% of normal levels as of March 25th, as the proportion of confirmed COVID-19 cases in Russia remains low, at roughly 3.4 per million.

Milan has the lowest activity of any city at 3%, and has been in shutdown for most of the month.

Although Singapore’s total COVID-19 cases grew from 18.8 to 95.4 per million, it still has 62% commuter activity. Interestingly, Singapore is one of the few countries that has been able to properly control and manage its COVID-19 outbreak.

Biggest Weekly Declines

As the month progressed, various cities showed stark one-week declines in commuter activity based on official healthcare recommendations and growing case numbers.

After a government lockdown announced on March 9, Rome experienced the sharpest decline of -75% commuter activity in the week from March 4 to March 11. Currently, there is only 5% activity compared to usual, similar to Milan.

In the second week of March, COVID-19 cases in France jumped fourfold, from 27.3 per million to 118.4 per million people. As a result, Lyon saw a whopping -91% drop in commuter activity—going from 97% on March 11 to 6% on March 18.

Over the past week, as cases in Australia reached 95 per million, Sydney and Melbourne exhibited the highest average declines at -36% and -33% in commuter activity respectively.

Flying High: The Top Ten Airline Routes by Revenue

This visualization tracks the high-value routes that generate the most revenue for airlines – primarily links between the world’s financial centers

Flying High: The Top 10 Airline Routes by Revenue

The airline industry is a tough business. Profit margins are narrow, airplanes are expensive to run and maintain, and government regulation and taxation can be onerous and unpredictable.

In addition, demand can stall by the outbreak of disease, recession, war, or terrorism. So when a company has a winning airline route, it makes all the difference to a company’s bottom line.

Today’s visualization uses data from OAG Aviation Worldwide, which tracked the airline routes that generated the most revenue from April 2018 to March 2019.

Top 10 Highest Revenue Routes by Airline

North American routes dominate the global rankings. However, it is the connections from the U.S Northeast and Europe that generate the most revenue and often the most delays.

Only one route breaks the billion dollar barrier: British Airways’ service between London Heathrow Airport (LHR) and New York’s John F. Kennedy Airport (JFK).

AirlineAirport PairCountriesTotal Revenue US$ 2018/19
British AirwaysJFK-LHR🇺🇸🇬🇧$1,159,126,794
Qantas AirlinesMEL-SYD🇦🇺$849,260,322

Singapore AirlinesSYD-SIN🇦🇺🇸🇬$549,711,946
Air CanadaYVR-YYZ🇨🇦$541,122,509

Air Canada’s route between Vancouver and Toronto bottoms out the list with $541 million of revenue in 2019. Low population density, high infrastructure costs, and an aviation industry that is essentially an oligopoly, are all factors driving up ticket costs in Canada.

North America, Top 10 Highest Revenue Routes by Airline

Here’s a look at only the top-grossing routes connected to North America, including the prior ones that made the global list.

AirlineAirport PairCountriesTotal Revenue US$ 2018/19

Delta Air LinesLAX-JFK🇺🇸$465,130,366
British AirwaysLAX-LHR🇺🇸🇬🇧$452,136,502

Transcontinental routes dominate the domestic market with LAX–JFK appearing twice in the ranking for both American and Delta Air Lines.

Asia, Top 10 Highest Revenue Routes by Airline

Despite Asia’s rise as an economic superpower, there are no routes that break the billion dollar barrier. Singapore Airlines’ Singapore (SIN) to London’s Heathrow (LHR) tops the list, generating $736 million in 2019.

AirlineAirport PairCountriesTotal Revenue US$ 2018/19

Singapore AirlinesSIN-MEL🇸🇬🇦🇺$414,276,407
Cathay Pacific AirlinesHKG-SIN🇭🇰🇸🇬$389,910,239

The routes that dominate Asia connect the financial hubs of London, New York, Singapore, and Hong Kong. There are also two domestic routes in Japan, connecting both Fukuoka (FUK) and Okinawa (OKA) to Tokyo’s Haneda (HND) airport.

Africa, Top 10 Highest Revenue Routes by Airline

At the top of the ranking in Africa is Johannesburg (JNB) to Dubai International Airport (DXB) with revenues of $315 million. Dubai has become an important hub for high value flights arriving and departing Africa, a position that may prove profitable as air traffic on the continent increases in coming years.

AirlineAirport PairCountriesTotal Revenue US$ 2018/19

British AirwaysCPT-LHR🇿🇦🇬🇧$174,605,201
EmiratesMRU-DXB🇲🇺🇦🇪$163,952,609

Despite the smaller earnings compared to larger markets, some airline companies see the potential for growth in Africa. Virgin Atlantic will fly a route between London’s Heathrow and Cape Town in South Africa, while Qatar Airlines acquired a stake in RwandAir.

Financial Hubs

The cities that appear in the top revenue ranking are revealing. Since business and first class travelers are such an important revenue driver, it makes sense that connections between the world’s financial hubs are delivering big value to airlines.

As Asian and African economies continue to evolve, what route could be the next billion dollar route for airlines?
