Animation: The World’s Largest Megacities by 2100
Throughout the course of human history, the biggest cities have always seemed impossibly large.
For many millennia, it was almost unfathomable for a city to sustain more than 1 million residents. In fact, it wasn’t until the 19th century that the largest cities globally, such as London and Beijing, were able to consistently hold populations beyond that impressive mark.
Despite this, in the modern era, we’ve quickly discovered that a city of 1 million people isn’t remarkable at all. In China alone, there are now over 100 cities with a million people today – and as such, our mental benchmark for what we consider to be a “big city” has changed considerably from past times.
Just like a city the size of modern Tokyo was hard to imagine for someone living in the 19th century, it can be an extremely difficult thought experiment for us to visualize what future megacities will look like.
Researchers at the Global Cities Institute have crunched the numbers to provide us with one view of the potential megacities of the future, extrapolating a variety of factors to project a list of the 101 largest cities in the years 2010, 2025, 2050, 2075, and 2100.
Today’s video uses this data – it’s also an extension to the previous work we did based on the report here.
The Largest Megacities by 2100
According to the report, human geography will look completely unfamiliar by the turn of the century.
Here is a list of the 20 largest megacities projected for 2100:
|#3||73.7 million||Dar Es Salaam||Tanzania|
|#14||40.9 million||Blantyre City||Malawi|
|#20||35.8 million||Addis Ababa||Ethiopia|
By the year 2100, it’s estimated that 13 of the world’s largest megacities will be located in Africa. Meanwhile, India will hold three of them – and there will be zero of them found in the Americas, China, or Europe.
Here’s a final look at the top three:
#1: Lagos, Nigeria
Nigeria’s largest city, Lagos, is expected to push the limits of how big a metropolis can get. Already, Lagos has seen explosive growth over the past few decades, and is growing so fast that no one really knows how many people live there. Over 2,000 people emigrate to the city every day, and current population estimates vary widely from 11 to 21 million inhabitants.
Either way, by the turn of the century, Lagos is projected to have a population north of 88 million.
#2: Kinshasa, DRC
Kinshasa, the capital of the Democratic Republic of Congo is projected to be the second largest city in the world with a population of 83 million.
#3: Dar Es Salaam, Tanzania
Dar Es Salaam, a city on the coast of Tanzania, has a population of just 4.4 million today. By 2100, its population is projected to jump by a whopping 1,588%, putting the total at 74 million inhabitants.
Ranked: The World’s Top 10 Automotive Exporters (2000-2022)
Data from the World Trade Organization highlights the world’s 10 largest automotive exporters in 2022.
Ranked: The World’s Top 10 Automotive Exporters
According to the European Automobile Manufacturers’ Association, over 85 million motor vehicles were built around the world in 2022.
In this graphic, we add context to this massive figure by ranking the world’s 10 largest automotive exporters. The list is based on data from the World Trade Organization (WTO) and includes countries from nearly every corner of the world, highlighting the global nature of the industry.
Top 10 Exporting Countries
The data we used to create this graphic is included in the table below. It represents each country’s share of the total export value of global automotive products in both 2000 and 2022.
“Automotive products” are defined by the WTO as motor vehicles, parts and accessories for motor vehicles, and internal combustion engines for propelling said vehicles. This grouping excludes motorcycles and trailers.

|🇰🇷 South Korea||2.6%||5.1%||+2.5|
From this list we can identify which countries have experienced the most growth or decline over the past 22 years.
Countries With the Most Growth Since 2000
The automotive exporters that grew their share of global value the most since 2000 are China (+7.7 pp), Mexico (+3.2 pp), and South Korea (+2.5 pp).
There are clear drivers behind each of these growth stories.
For example, China became the world’s largest car market back in 2009, which accelerated the growth of its domestic automakers. China is also home to some of the world’s biggest automotive suppliers, including Weichai (diesel engines), Hasco Automotive (drivetrain and air conditioning systems), and CATL (EV batteries).
Mexico, on the other hand, has grown its auto industry by enticing global brands to construct their factories there. The country’s competitive edge includes cheaper labor and a land border to the United States.
Finally there’s South Korea, whose growth is largely attributed to Hyundai Motor Company. The Seoul-based automaker recently became the third largest on a global basis, trailing only Toyota and Volkswagen.
Countries With the Biggest Decline Since 2000
The automotive exporters that declined the most since 2000 are Canada (-7.2 pp), Japan (-6.4 pp), and the U.S. (-2.6 pp).
Canada’s auto industry has experienced a steady decline in recent years, though new EV-related investments could turn things around. In March 2022, Stellantis and LG Energy Solutions announced the construction of a $3.5 billion EV battery plant in Windsor, Ontario.
Canada’s automotive industry is largely concentrated in the province of Ontario, which neighbors Michigan, the top state for U.S. car production.
